Took mine out today for a test drive and had some issues with it. Rounds were not ejecting always and when they were it seemed like they were only falling a foot or two away from the rifle.
Here is a cold link to my Photobucket of the AR10 having issues every few rounds with ejecting the spent casing. http://vid1052.photobucket.com/albums/s444/brendanb4381/IMG_1700_zpsib7lijix.mp4 This happened with 2 20 rd Pmags and 1 25 rd Pmag. We were shooting Privi 145 grn FMJ and surplus Australian 7.62 Ball ammo. When I got home and checked out the BCG it seemed pretty dry and the bolt didn't want to move easily within the bolt carrier. I know we are supposed to break these in with making sure the BCG is dripping wet and I sprayed the BCG down a couple times with Remington Oil but never made sure anything was in sprayed between the bolt and carrier (I forgot to do this was running way behind this morning getting ready). From others experiences with this platform can this cause this type of problem? I won't be able to take it out again for about a month but I will be using Tetra Gun Grease on the bolt, carrier and everything inside the upper receiver in which the BCG will be making contact with to make sure it is lubed as much as possible. I am using a buffer spring and buffer from Palmetto State Armory and I do wonder if this could also be leading to an issue. It is the PS PA10 carbine buffer spring and the PSA H-Buffer. |

I installed the same buffer/spring combo from PSA. Did not have those issues. Mine was ejecting from 2-3 oclock 5ish feet away with ZQI once I removed the brass catch. I sprayed CLP all over the bolt and internals before running it. Unfortunately I thought I'd get to shoot it again this weekend to test it past the inital 50 rounds but ran out of time and had to just plink some rounds through the XT22 in the back. Fun...but no AR10.

I decided today I am gonna just upgrade the BGC to one of KAK Industries Dual Ejector 308 BCGs and swap out the carbine stock setup for the PSA PA10 rifle tube/spring/buffer setup and slap on one of the Magpul AR10 PRS Stocks on it. This next time around it better work perfectly or else. I am gonna even lube up the BCG and receiver with the tears of liberals.

While I haven't ordered it yet, I think i'm going with the PRS for mine as well. I did snag an SSA on sale. Still looking for glass.

Finally got the chance to unload all the mags and ammo that we took out Sunday and I actually only put 1 20 rd PMag and 1 25 rd PMag through it. Went back and looked at video of myself and my brother in law each shooting a mag through it and there was 4 times out of 45 rounds in which a spent casing didn't clear the gun completely upon ejection but was snagged as pictured in the video as the BCG was chambering the next round.
We didn't have the ability to do any sort of bench shooting so every shot was taken either standing up attempting to lay out in a prone position on a wet and somewhat muddy field or sitting and kneeling. I was originally trying to go with the carbine 6 position buffer tube type setup (Palmetto State Armory PA10 buffer tube kit) with a Magpul ACS-L stock (which I like a lot on a couple of my go to AR15s) but damn did this not really feel that comfortable up against my shoulder nor did it really feel 100% rock solid on an AR10 compared to an AR15. I am hoping the PRS on a rifle buffer tube will feel like a rock solid setup. Now I am off to the EE to throw up for sale the PA10 Buffer Tube Kit and Pro-Fab BCG which have a total of 45 rounds through them.

I wanted a PRS initially but it was a little spendy...not to mention Heavy on an already HEAVY rifle. Ended up with an STR. If you want to bench it and are willing to cough up the coin, the PRS looks like a solid setup.

Put another 70 rounds through mine today. No issues. God damn I don't know why I didn't build an AR10 sooner. This is absolutely my favorite rifle. I was shooting a 10"plate at 150 and then 200 yards. 150 was a cinch with zqi. Spread was 4-6". Popped a 20 round group and it was 7inches. When I moved to 200 the zqi fared alright on a cool barrel. I'd be on plate with a 10rd magpul center of aim and all over the plate. When the barrel heats up however, I started missing...a lot. I could play with zqi on my silhouette at this range but I'm not sure how much farther I could push that bullet with great accuracy. Need to try some heavier loads but loving this thing.
ETA: Looking at the pic I have looks like my scope hits zqi low at the 200 hash. Will have to pull up the drop chart for my scope again to confirm. Ran into dusk again towards the end so it was my range session. Will adjust next time if shooting here. Always on a time crunch. |

I budget built this one last week.
The trigger is a RA-140 SST, a B5 Bravo Sopmod stock, Burris scope mount, and Primary Arms scope. Lower build kit is from PSA. Total investment is around $1350.

I've ran about 45 rounds through it. I like it, especially compared to a Milspec trigger. I've not shot for groups yet, but I'll report back when I do.

Built mine a few weeks ago. Wanted to pass along a couple of things learned the hard way. Used a 308 kit from PSA for the Alex stripped lower. Once I started the build I noticed the pins included with the PSA lower lit were too short. This made me wonder if either I had received AR15 pins in the kit as an error (and doubt the buffer/spring as well) or if PSA uses the same length pins as an AR15. I ordered DPMS 308 pins from Grafs to finish the bid and took it to the range just to see if it would cycle. No issues with 7 rounds just shooting into a dirt bank. Did notice that the gun had quite a bit of slop between the upper and lower which led me back to the pins. The DPMS pins I had ordered had a bit of a flat bottom to them which allowed a small gap /rattle between the upper and lower. I ordered the ones from Alex Pro and they were noticeably more rounded. Swapped them out and much much better fit. Have a set of weaver rings holding a 5-25 weaver scope. Have yet to dial it in. So far I am impressed. Build was quite a bit of fun.

Hey guys, has anybody used just the stripped lower as a starting point and then built out an upper from a different manufacturer? Is that possible with this lower? I am wanting an aero M5 upper, or perhaps a Midwest or something, but this seems like a nice way to go on the lower receiver. I'm just not sure about compatibility issues between this lower and other uppers?

These are interesting to me. Appears that either a carbine or rifle length buffer assembly are usable, correct?
OP mentioned a '.308' buffer, is that recommended/necessary? |

Alexandria Profab is the manufacture and designer of the upper and rail system. It is also the company that started Alex Pro Firearms. The owner of Alex Pro Firearms is a son to the owner of Profab. These parts are all overstock and excess material but are new and not returns that is why they are priced so well. This price will be going away as the extra materials are consumed. Also there will be a few new uppers launched by Profab through Aim so keep watching for them. You can also buy the rail kit from Aim.

Any comment on my question about lower compatibility with other uppers? Could I build out one of your lowers with the appropriate parts kits and attach it to a 308 upper of a different manufacturer, or is there some proprietary considerations that wouldn't allow that? |

For the most part if it is a DPMS pattern upper it should fit on this lower. Just like the AR15 platform some brands play better with others when it comes to how tight or lose they are but pivot and takedown pins should line up.
EDIT: Warning I didn't stay at a Holiday Inn last night, only a Motel 8 so it never hurts to Google and see if there are known issues with the upper you are considering with other companies lowers. If you do not stumble across anything on Google with Brand X upper not working with say a PSA PA10 lower or something similar you should be good to go.

Do you guys' Alex 308 ARs leave extractor marks on the brass? I can see marks on mine. Ejection is fine, only kicks 5-6 ft away. My 308 AKs are not doing so, they dent brass but no extractor marks! Just curious.

Just curious. I will let you know in a couple weeks. My build has been updated to the Magpul PRS AR10 stock on a rifle tube with a new LBE Unlimited buffer and spring along with I swapped out the BCG for a new one from KAK Industries that has the dual ejector. If this time around I still have issues with some rounds not ejecting and getting caught in the firearm I think I am going to just part the damn thing out and use the funds towards something else.

Range report for my APF 308.
I shot the APF and my Savage 10FP to see the accuracy difference. The APF shot just as accurately as my Savage and my buddies Rem 700 at the 100 yard line. I did not measure the group but 5 shots of Freedom reman 168 gr HPBT grouped really well. I also got a decent group with Fed XM80CL but it was about double the size of the Freedom. Last I tried a box of ZQI and is patterned like a shotgun at 100 and I could barely keep it on a paper plate. The holes outside the 5 shot group at my trying to get the ZQI to hit with limited success. Keep in mind I am new to accuracy shooting and I am trying to get over a mean flinch that throws my shots right. 
Specs, APF complete upper and stripped lower. Geissele SSA trigger Mil spec LPK DPMS LR-308 buffer Ebay 308 takedown pins 308 Rifle buffer spring Brunton Eterna 6-24x40 scope YHM Phantom 308 Supressor 
I did have some signs of over gassing using the can and will be looking for an adjustable gas block in the future. I also have the opportunity to try out a Jewel trigger to replace the SSA as I found it heavy for a target gun. With a few tweaks I think these can be turned into decently accurate rifles for a sub 1k budget price. |

I just ordered my APF 308 AR10 stripped lower. I also scored a Rainer arms 16" middy match barrel for 200. I plan on running this setup suppressed pretty much all the time. Does anyone have any experience running the gibs side charing upper? I think that coupled with an adjustable block would be a nice suppressed setup. Also I think it would be sweet to run subs with the side charger vs a handle.

I finally finished putting mine together and will try to get out to the range next week.
APF complete upper and stripped lower Few parts from a random Mil spec LPK I had laying around UTG complete buffer kit & A2 stock Ebay 308 takedown pins PA 4-14 scope w/ 308 HUD in Aero mount Harris bipod attached via APF rail and YHM sling adapter As it sits now with an empty IMI mag, it clocks in at a fat 12lbs 5oz, but just under $1000 as the Harris was borrowed from another gun of mine. Depending on how it shoots, I have a Larue MBT on the way that I may drop in and eventually I'd like to swap the A2 stock for a Magpul rifle stock to shorten the LOP a bit. The rail could stand to shed a bit of weight, but for now it appears like it will work just fine for the price paid.

I used the same pins, they arrived very quickly, and actually included extra detents.
I found it useful to trim the spring for the rear pin a bit to keep it from popping out from under the grip when installing. |

I decided today I am gonna just upgrade the BGC to one of KAK Industries Dual Ejector 308 BCGs and swap out the carbine stock setup for the PSA PA10 rifle tube/spring/buffer setup and slap on one of the Magpul AR10 PRS Stocks on it. This next time around it better work perfectly or else. I am gonna even lube up the BCG and receiver with the tears of liberals.

Took mine out today for a test drive and had some issues with it. Rounds were not ejecting always and when they were it seemed like they were only falling a foot or two away from the rifle. Here is a cold link to my Photobucket of the AR10 having issues every few rounds with ejecting the spent casing. http://vid1052.photobucket.com/albums/s444/brendanb4381/IMG_1700_zpsib7lijix.mp4 This happened with 2 20 rd Pmags and 1 25 rd Pmag. We were shooting Privi 145 grn FMJ and surplus Australian 7.62 Ball ammo. When I got home and checked out the BCG it seemed pretty dry and the bolt didn't want to move easily within the bolt carrier. I know we are supposed to break these in with making sure the BCG is dripping wet and I sprayed the BCG down a couple times with Remington Oil but never made sure anything was in sprayed between the bolt and carrier (I forgot to do this was running way behind this morning getting ready). From others experiences with this platform can this cause this type of problem? I won't be able to take it out again for about a month but I will be using Tetra Gun Grease on the bolt, carrier and everything inside the upper receiver in which the BCG will be making contact with to make sure it is lubed as much as possible. I am using a buffer spring and buffer from Palmetto State Armory and I do wonder if this could also be leading to an issue. It is the PS PA10 carbine buffer spring and the PSA H-Buffer. I installed the same buffer/spring combo from PSA. Did not have those issues. Mine was ejecting from 2-3 oclock 5ish feet away with ZQI once I removed the brass catch. I sprayed CLP all over the bolt and internals before running it. Unfortunately I thought I'd get to shoot it again this weekend to test it past the inital 50 rounds but ran out of time and had to just plink some rounds through the XT22 in the back. Fun...but no AR10. I decided today I am gonna just upgrade the BGC to one of KAK Industries Dual Ejector 308 BCGs and swap out the carbine stock setup for the PSA PA10 rifle tube/spring/buffer setup and slap on one of the Magpul AR10 PRS Stocks on it. This next time around it better work perfectly or else. I am gonna even lube up the BCG and receiver with the tears of liberals.
Was able to take this out again yesterday and put 3 mags through it without any issues at all. Looks like the upgrade to the KAK BCG along with switching things out to a rifle tube/buffer/spring and throwing a Magpul PRS stock on it took care of any issues with it cycling and ejecting rounds correctly. Damn this is a heavy configuration now though. :) |

I just ordered one of these for my stripped PSA lower. Will I need the extended pins for it or is that just for the APF lower?

I also bought the upper from AIM. I had purchased a DPMS Oracle LR 308 carbine with the 16" barrel back in January. I got it for a steal at Rural King for $600. It was one of their daily deals. I wanted an 18' with FF handguard to make it more of a precision 308, but figured at that price I could change anything I wanted. I really like the upper, and in-fact, I really like the handguard. I purchased a small piece of rail from APF to mount a UTG ractical bi-pod. They were very helpful. I changed the stock to the LuthAR carbine stock and used a Hogue grip. For optics, I put a Nikon M308 scope w/BDC and a set of Amazon 45 degree irons. The DPMS trigger was horribly gritty, so I ordered a Geissele SSA that should be here this week. I have about 60 rounds through it, and I believe it will be a good shooter as soon as I get the trigger situation remedied. Here is is stock: <a href="http://s46.photobucket.com/user/jlgil73/media/Gun%20Stuff/IMG_20151230_082551_zpsj0idzigu.jpg.html" target="_blank">http://i46.photobucket.com/albums/f105/jlgil73/Gun%20Stuff/IMG_20151230_082551_zpsj0idzigu.jpg</a> and with most of the new goodies... <a href="http://s46.photobucket.com/user/jlgil73/media/Gun%20Stuff/IMG_20160303_000818_zpseitw3eoc.jpg.html" target="_blank">http://i46.photobucket.com/albums/f105/jlgil73/Gun%20Stuff/IMG_20160303_000818_zpseitw3eoc.jpg</a> Do you have a nipple on you toe? |

I have the lower. Can someone help me, can I put any barrel on it? Does it have to be DPMS style or anything? I have never dealt with a 308 AR and this is all new to me.

Done some 50yd shooting and look to be .75 with 147 , wanting to stretch it to 100 and use 168. I think I might put a larue trigger in it firs. I can watch my impacts at 100 with that SJC brake.
