Finally got my bolt in and when attempting to cycle a round the bolt will not go into battery with a round in the chamber.
The first time I attempted it the gun was together and it was stuck and the round would not extract. I disassembled the gun and tried again to take these pictures. I believe the chamber might not be up to spec as the round does not go into the chamber fully not allowing the bolt to go into battery. I also noticed when disassembling the bolt that the cam pin either does not rotate like other ar's or the hole is on the wrong side this also might cause an issue. You can also see brass on the bolt face. Album of pics |

The hole in the cam pin is right. The cam pin does not need to rotate to install. Sounds like you have the dreaded short leade or free bore. Your bullet might be getting stuck in the rifling.

Are you sure you have the correct buffer and buffer spring? I had this problem when they sent me the wrong buffer parts on my complete lower.

It does seem to be the stainless ones, both the 16" and 18" barrels. My buddy picked up a complete p-tac .308 and I measured the free bore on his, any longer and the bullet would need a bus transfer before it could get to the rifling. The fit and finish on the p-tac was a lot better than my PSA. My upper has a lot of wobble on the lower. Still would like to know how PSA is test firing guns that will not chamber a bullet. Maybe they should test with ammo that the customers are going to be feeding it. |

Add me to the list of failure to chamber/eject. Mine is the 18" ssk upper ordered 12/21. Im'd PSA, I'm sure they'll make it right, but it sure is frustrating.

Maybe they only test complete rifles and not barreled uppers? He bought an upper without BCG..... They claim to test fire them all but that obviously is not true as it is 100% impossible for them to of fired this upper. Quoted:

I just came across this thread and starting to get concern because I just finished putting together my PSA 18" Mid Length 308 WIN 1:10 SSK15 Rifle Kit mated with PSA PA10 lower.. Besides running into the bolt catch release being a little tighter than normal I have not noticed any problems. However, I have yet to take it out to the range.
I saw somebody posted that this issue only existed on uppers with 16" and 18" stainless steel barrel. My kit came with an 18" barrel so i am concern. Is there anybody that bought the PSA 18" Mid Length 308 WIN 1:10 SSK15 Rifle Kit and did not run into this issue of the bolt not going into battery with a round in the chamber? Thanks! |

View Quote You can test the issue easily put a mag in loaded with a round. if the gun wont go into battery (bolt fully forward and locked into place) then there is an issue. If not then you are golden. I would try it with the upper off the gun incase you run into the issue I had where the bolt is back and not stuck on the lower. Since it also would not extract the round I had to use a cleaning rod to push the round out. If the upper is not on the gun then the mag will not work just drop a round into the chamber manually to test. |

View Quote I bought my PSA 18" Mid Length 308 WIN 1:10 SSK15 upper w/BCG and handle back in September and haven't had a single problem like the recent ones have. It's mated to a PA10 lower I put together using a standard Carbine Mil Spec buffer tube, short 308 buffer and 308 Carbine spring. Mine had obviously been test fired before they shipped it out. Light brass marks on the bolt face, carbon in the flash hider and the barrel was lightly fouled. At first, mine left light scuff marks on one particular spot on the brass (not unusual for a gas gun) and the extractor beat up the case rims a bit more than normal. After about 200 rounds the extractor damage calmed down to what I would call normal and I expect it to decrease even more with time. I've had 5.56, 6.8 and 300BO extractors do the same until they break in. The brass scuffs also decreased and I went ahead and buffed the chamber well with Bore Paste and a tight patch and the scuffing disappeared completely. Mine loads and fires anything I put into it including mild reloads, moderate to heavy reloads, commercial Hornady and Federal and the cheapo M80 149gr Federal (LC) PSA sells for $11.99 a box. I do get what I initially thought was primer cratering on fired primers but looking carefully it looks like the bolt face pin hole is ever so slightly oversized or the firing pin head is minutely undersized. That isn't causing any issues I'm concerned with so it is what it is. I have a 5/56 AR that does the same thing. These PSA barrels are right at minimum 308 Win specs though. My fired brass (all of it) will still drop right into my Dillon case gauge before resizing. I have never had gas gun fired brass do that. My standard sizing die barely touches the case sides when I FL size it. I might actually be able to neck size brass fired in this rifle and still have it function flawlessly. Overall, I'm very happy with the rifle and it shoots well within my accuracy expectations with cheaply thrown together reloads, commercial ammo and the Fed White box crap (only bought it for the brass and rifle break in). With my reloads of 44gr of 4064 behind some inexpensive 168gr FMJBT bullets I've had for years it's punching 1.5 MOA. Better put together loads, with quality bullets will only make that better. |

The previous issue that I was having with the bolt catch release being too tight has been resolved. Pulled out the roll pin and ran a hole hone on the bolt catch button and it loosened it to where it feels like any other bolt catch release button I have on other AR's. I also noticed that the ejector on the bolt was pretty stiff and was not retracting. Took out the roll pin and the ejector and it's spring from the bolt and honed and lubed the ejector hole and re-assembled it. Loaded rounds on the mag and to my delight the bolt went into battery each and every time. I have yet to take it out to the range though. If I'm able to get to the range this weekend and I'll post an update.
Thanks! |

I am having the same problem with my PA-10 the bolt not fully seating, but I have a CMMG barrel. not sure what is going on but the pictures the OP posted look just the way my bolt is when I release the bolt carrier, but I have found different ammo affects it, using reloads it will not seat, using some monarch ammo the bolt will go home with no problem but I have to tap it out with a rubber mallet on the charging handle. I did manual cycle the bolt about 50 times prior to trying to seat the bullet. I think it needs to be shot to wear everything in but I just dont know at this point I hope to take it out and shoot it this weekend, will update later once I see what happens. I will have on two pairs of gloves just in case....... OK update to what I did last night, I took apart the bcg and polished the cam pin, and the raised area round the bolt, looks like a belt with no buckle, anyway I reassembled the bcg and then took a punch and pushed in and out of the ejector about 150 times, not all at once but over about 30 min, at first it was hard and felt like it was crunching up something, then later it smoothed out and now pushes easier and much smoother. Now I can fully seat a reload and eject it with my hand,(before would just jam up) its still a bit stiff but nothing like it was. seems like that was causing my problem. will still try and shoot it in a bit. I also lightly polished the smooth part of the extractor not mirror or anything but just enough to where its very smooth. making progress......... final edit, took it out and it ran just fine, no issues, the bolt did show the same brass smearing as some of the pictures shown. so if you are having issues try to work the ejector and see if it helps. |

PSA received mine last Tuesday and received the UPS shipping notice this morning that it should be back tomorrow morning. I know the stiff extractors have been discussed , but I found some videos on you tube last night where people made videos showing the chambering/ ejecting problems. Their problem turned out to be the extractor spring. Search PSA PA10 on you tube. Might save someone the trouble of sending the upper back. Could turn out to be my problem as well. No idea what they did to mine or if they just replaced it yet.

I bought 2 rifle kits; an 18 ss with MI g2 rail; and 18 ss with MI ssk rail on 12/18 and 12/19. Both were stiff when first assembled; one very stiff and it was difficult to get bolt unlocked on even an empty chamber; non psa logo bolt carrier. Both showed brass from test firing and empty case in box. I did some research and watched some videos and etc. I pulled both apart and oiled and cleaned well. Disassembled both bolt carriers and worked both extractors with an empty case using a light weight oil to get inside the tight areas as to not fully disassemble the bolt. Both chambers were scratching cases. Cleaned chamber with chamber brush and oil; most scratching gone and similar to other ar's. One worked flawlessly once cleaned well and oiled; psa logo bolt carrier. The second still had a little "snag" when unlocking the bolt; I worked the charging handle an inch at bolt lock up about 50 times and it is much better now; the lugs are making contact and wearing in slightly; non psa logo bolt. Both now chamber rounds fine. Both have free bore and chamber 150 grain. Now to shoot them. Should be fine deer rifles.

Well I got mine back today after only a week with absolutely zero info/paperwork on what they did, if anything. First try to chamber a factory round had exactly the same results as before I returned it. After reading about stiff extractor problems, I took the bolt completely apart and cleaned/lubed it. I can now at least get it to chamber a round, but I cant manually get it to eject the round,I still have to take the upper off and tap the bcg out with a hammer. Im going to keep working on the bolt I guess and see if it breaks in. This is the PSA NIB BCG

If you did not remove the ejector then you did not take the bolt completely apart. If you're able to, try to remove the ejector. Remember to compress the ejector prior to taking the roll pin out otherwise you are going to mess up the roll pin and your roll pin punch. Put the bolt on a vise (ensure that you have some layer on the vise so you won't marr the bolt) with a punch or spent .308 case, compress the ejector then hammer out the roll pin that holds the ejector. If you're still not able to remove the roll pin that holds the ejector. I would just use the spent .308 casing or .308 round to compress the ejector and try to repeat this process until the ejector loosens up. Apply some lube on the ejector so that it work it's way down there and loosen it up. Hope this helps! |

lay the BCG on the floor/desk and drip some oil on the ejector, take a punch and work it about 150 times or so, clean then oil the crap out of it, if you have a dremel clean up the face of the extractor not mirror just make it smooth and see if that helps, I did that to mine and it works. also I took the bolt out and cleaned up that little belt that runs around it, not sure what its called but I did make that mirror smooth so the bolt slides in and out easier. hope you get it fixed I know how it feels View Quote View All Quotes View All Quotes Quoted:

Well it looks like y'all were right about the ejector. I put the BCG in a vise with the bolt facing up. I soaked the bolt face around the ejector with Slip 2000 and let it soak for a few hours. I was finally able to get it to move by pressing it with a punch. It's finally working like it should. (Still haven't fired it yet) thanks to everyone for the good advice. It would be nice if PSA would let you know good, bad, or otherwise what they find when you send the upper back. I'm convinced most people with the same problem could be spared the headache.

View Quote Glad it's now working out for you!! Overall, I'm happy with the PSA 18" MID LENGTH 308 WIN 1:10 SSK15 RIFLE KIT + PSA PA10 lower that I purchased. Only issues I have were as follows: - Required mod to my Geissele SSA-E trigger to install it on the build. Ended up not installing it because I did not want to mod the SSA-E.. I ended up using a ALG Defense ACT trigger instead. - Tightness on the bolt catch release button - Stiff ejector that caused the bolt to go into battery. - Stiff extractor springs - Dirty or Gunky bolt face (prob one of the worst i've seen) Would I buy again? I would probably not buy the rifle kit because I want to get the Nickel Boron BCG instead of the BCG that came with the kit. Just too bad that PSA let these stiff ejector and extractor springs potentially damaged a successful launch of a new product line. |
