Hello everyone, I think this is the correct sub forum to start my build thread, if not mods feel free to move or delete the thread. Anyways I have been doing research for a few months and finally got around to ordering all of the parts, the first parts arrive Tuesday  . I will update the thread as parts arrive and as I assemble them. Here is the outline of my 6.8 SPR(ish) build that I plan to use for hog and deer hunting.
UPPER: PSA blem upper receiver PSA dust cover and forward assist PSA full auto 6.8 BCG YHM low profile gas block Franklin armory 13" hand guard BCM gunfighter charging handle PSA A2 .30 cal flash hider Wilson combat 18" match grade barrel mid length gas tube LOWER: PSA blem lower reciever (absolutely no blemishes that i could find) PSA lower parts kit with a Geissel SSA trigger magpul ACS-L stock and PSA milspec buffer tube I still haven't decided on optics, academy has a leupold for 249 if i remember correctly that peaked my interests. As far as the head space between the PSA BCG and Wilson Combat barrel do I need to check head space after the rifle is assembled, I have read conflicting information on the interwebs, and if so what is the best way to accomplish this? Also if I am forgetting something or have parts that will not work together feel free to correct me. |
| Alright awesome thanks for the response. Now if I decide to test fire it before checking head space will the rifle function flawlessly and then fail all at once, not function at all? I am also wondering if there a way to tell if there is improper head space via inspection of empty brass or paying attention to the rifle as it cycles or anything along those lines? I think I am probably making this out to be a bigger issue than it needs to be but I would prefer to keep part failure at a minimum while dealing with expensive parts around my face haha. |
Okay guys well here are the parts that I have thus far. I don't have 50 posts yet so they will only show up as clickable links.
I was unaware that the charging handle has 5.56 marked on top so I may save it for my next build which is already in the works  . Also as you may have noticed the rear site is OD green, I don't have any plans for a green gun so i'm not sure what i'm going to do with it haha, I think I was drunk at the time of ordering  . I still have two more orders with the rest of the parts that I don't believe have shipped as of today.

You get mixed opinions on checking head space because everyone is different. I agree that if you buy quality that everything should be in spec. It is my opinion that checking head space is a good thing and should be done no matter whose parts you use. It takes only a few minutes and the gauges are not TOO expensive (they aren't cheap either). The point of checking is to guarantee that there was not some sort of error in maintaining specs in the bolt, barrel or both. Why risk injury or worse to just skip over something. As most here will agree, build one and your sucked in for life. Get the tools and do the job correctly. Again just MY opinion, Form your own and good luck!!

Just run over to your local gun smith and ask them to headspace it, it takes seconds and it give peace of mind. Then you dont have to spend 100 on gauges But if you spend $100 on the gauges you'll have all the more reason to buy more parts and build more AR's, because after all, you did spend good money for the gauges.

This is how the actual headspace measurement is determined for a 5.56mm/.223 REM chamber. Subtracting the bolt measurement in the red box, 0.156", from the barrel measurement in the red box, 1.6206", equals 1.4646" This is the minimum headspace listed in the milspecs for a new barrel that has been high pressure tested (HPT).

Thanks for all the replies guys, is there a place online that sells go no go gauges that can be used with out removing anything from the bolt face? The only ones I have found will require removing the extractor which I don't think would be too difficult but I have read to expect flying parts.

Looks like you are well on your way! What build tools do you already have? You wil need some basic specialty tools. Barrel Wrench, Roll Pin punches, small allens, etc. The tools are NOT expensive. You can get high quality with great value for the money!
If you need any help with specific tools let me know. I purchased only what I needed. I did not buy a Kit of toolls. I got only what you NEED. Well done on your parts. Your rifle is gonna be Bad A$$ Tony PS Taking apart your BCG is really easy. I take my extractors apart all the time to clean. I have never had a part grow wings and fly away. |
The first pic is the packages I received today, the only part I am still missing is the forward assist. The second is obviously everything laid out together. Now I need to order some brass punches, Roll pin punches, a gun smithing hammer, a upper receiver vice block and I believe that will be everything I need. I should start putting the lower receiver together starting next week. |
Well guys I got bored and the result is BOOM!!!!
Sorry about the crappy iphone pics, I am still missing the forward assist and the BCG. I was able to complete the lower without any punches or a gun smithing hammer. I just used electrical tape on a regular hammer and a set of channel locks and used the "squeeze pin" method wherever applicable. I noticed that my flash hider didn't come with a crush washer, so it is loosely covering the threads from damage until one can be purchased. So go ahead and tell me what you think. Now optics shopping

Haha thanks, the grip will eventually get replaced, I just need to figure out which one I like most first I personally have the moe+(the rubber moe grip) and i like it. However i like the BCM mod3 i think because of the extention under the trigger gaurd, protects the tangs for the trigger gaurd from digging into your finger if you have a high and tight grip. |
