When I assembled my first AR years ago, it seemed lower parts kits were lower parts kits and besides triggers there wasn't a ton of other parts that were not "mil-spec" or something claiming to be.

the big thing then was triggers and ambi safties. and charging handles.

so for your builds, what do you like for all of the small parts.


for me I like ambi safeties. I always preferred the b.a.d - c.a.s.s with a full size on one side and short throw on the other. I see a lot of people stepping up and going for the talon now but realistically there are so many I'd wonder what options people picked.

I've tried different mag buttons. not many. I prefer the mil-spec stuff.

I have 3 different charging handles. raptor, geissele, and the BCM with he large catch. I prefer the geissele

I like the vltor a5 buffer system

I haven't gotten into different bolt catches.

I do like slightly longer dimpled takedown pins. especially because some of mine are so tight I need a tool to pop the pins.

and I generally have all colt pieces for the pins and springs and all that.


so what's your go-to setup for building out an upper and/or lower?
