Ok so I was told that you cant build anything much less an 80% AR15.. So I am! Rules.... Has to beat my uncles $400 used PSA AR15. (Oh he just got one after missing a follow up shot on a coyote. Welcome to the dark side....) I am allowed to trade my "useless crap" to help finance it. SO.... All from NWFA Members... Thanks for the deals and trades. This is the mad scientist in action. Upper $50 +trades In 5.45 soviet. lower 80% $65 (ehh... its here now) S&W M&P15 Trigger and pistol grip with safety detent and spring $20 Thanks!!! And just today! Stock and buffer tube $20 Thanks as well! $155 so far... And got a couple parts coming in as well. I am hoping with help of my peers to document this for a christmas laugh for this relative. Pics... Think I have alot of work even after the build is done. The barrel is marked SA 5.45x39 1/8.... If anyone knows what SA stands for let me know! Now on to the thread. Earlier today I got a buffer and M4 stock. So as I am doing this I am missing a grunch of small parts. If anyone has any of them laying around I am glad to trade, barter, or just buy them. Takedown pins... I would lvoe some of the easy pull ones but I can get away with cheep stocks! on hard wear. Safety... Yes I do use it. Bolt catch stuffandthingies... Yeah thats what I was talking about. Spring and buffer, (buffer retaining pin).... Well thats going to be a discussion I was hoping to have here. I definitely got to post the extra parts I have from this build into classifieds... And where are the local 80% guys? I definitely need to get my hands on a jig and some advise as well! Anyone able to rent me the tools and jig for beer? And why am I doing such a cheep build in 5.45? Well because ammo is cheep and I want to dust up some coyotes in a bit!
