BTW, how often should I do a complete takedown, all pins, springs etc.?

That sounds great, that's why I went with Armalite. Charging handles: Looking at changing, is that only for comfort? Forward assist: Is this necessary? Bolt stops: do they wear out frequently? I think I am out of question and money! I greatly appreciate your input.

I am planning on running 200 - 300 rounds through it. Is that appropriate? I will be at the range for hours letting the unit to cool down and of course lunch. Being a machinist, My biggest concern is "FIT". On an Armalite is this a concern? Should I lap appropriate fittings? I am a long range shooter. I will be zeroing it in at 300 yds. I know this a carbine model (AR-10A DEF). So asking 300-500 yds maybe a stretch. Remember: Love dies if you shot it! LOL!

Thank You All. I Appreciate your knowledge. Remember: an Excursion always flattens the Prius!

Thank you very much. I noticed on the test that the Gamma or the Patriot Ordnance weren't tested. I guess there are too many options. I do like the results for the Precision Armament EFAB Hybrid, Brake, Compensator and flash hider. It's all just more research and work. I fear I may have the disease of buying enough parts to make another rifle.
