Im looking into building an AR-15. I have done research on the barrel already as i have settled on a 1:8 twist as it can shoot just about anything except the really light stuff. I have an idea of what stock i want, and the stripped lower also. What i am looking into now is bolt carrier groups, trigger assemblies, and gas/piston systems. What i would like to know about each is what are some good assemblies, the pros and cons, and some good resources. I know nothing about these. Also keep in mind I am not planning on purchasing my first part of this gun this year, so I am in no rush to get this project completed. I want this rifle to last a lifetime so i want to get the best.
what are u trieing 2 tell us? i dont understand what ur saying means? how are we sopposed to answer a question we dont understand? does everyone agree? truly, nicole.
I would recommend that you get a M-16 Full auto bolt carrier group (No it won't make your gun full auto without the parts for the lower). They are a little thicker and more heavy duty than the standard AR-15 bolt. Direct impingement gas systems work for me, and they also work for the U.S. Military. A piston system is supposedly heavier and can cause bolt tilt, plus they are ridiculously expensive. With a piston system you can adjust the gas port and it might save a little wear and tear on your gun and it runs cleaner. DI you are just kind of stuck with one setting and you get more carbon fouling in your action. Pick out whatever stock you like. I don't know what triggers to recommend I just use a basic nothing fancy trigger. I really don't think it matters what brand lower you get just make sure it's forged aluminum.
