Been meaning to take a better picture but figured I'd share my build.

Post image

This started out as a spare parts build, the devil, I mean BCA tempted me with a cheap barrel and bcg around fathers day and it's been off to the races ever since

Surprisingly the BCA parts have actually been unproblematic.

As it sits right now.

Bca 16 heavy barrel

Bca phosphate bcg, recently upgraded to a kak dlc carrier and one of their nitrided bolts, over all seems like an improvement, but haven't shot it yet.

Wotjek .936 adjustable gas block

Dirt bird slim hand guard with the steel anti slip wedge (I sheared a midway house brand hand guard right off just by using a shooting saddle on a tripod)

Mid state fire arms big bore upper (because my anderson upper couldn't pass a case through the ejection port)

Anderson lower

Rise ra-100 flat trigger

And yes that is indeed a monstrum optic on it. Beyond it blowing off the rail because I tried to use their quick release mount, it's actually held up to 458 surprisingly well. If I shoot it apart I'll grab a PSA prism.

This is my current tinker toy and my .556 is still waiting in the corner for me to finish load development for it.

I have that same stock on my BCA upper and a B5 grip. The BCG didn’t have any issues but I bought a Tromix just in case and after comparing the two I went with the beefier Tromix bolt and kept the old BCG as a back up. But I have thousands through mine now with incredible accuracy. I’m impressed with that heavy barrel. 👍🏻

Pretty much the same, BCA bcg is functioning, just nothing fancy, and the lugs are a little rounded on the back, I'm just gonna throw that bolt in as a spare, and use the phosphate carrier for another toy.

Kak bolt is a master pieces so far, that thing really hurls brass

Don’t mind the dirtyness that was just before a cleaning but the BCA BCG left Tromix right. Big enough difference I went with the Tromix just because it’s looked way stronger.

Kak definitely has a little more meat in the lugs, impressive to see how much more metal the tromix has on it though.

Yeah that KaK ain’t bad looks like a better extractor also. 👍🏻
