BCA Upper accept other BCG?

[js8588]

Have you built any using a BCA upper and one of the ones you mentioned. I just hate to buy one and not work. To have to turn around and buy something else.

I've owned a couple of the BCA ones back when they had the dual charging uppers (retained rear charging handle as well as the right side charger).

There's nothing wrong with them. I currently have 2 of the Lantac side charging uppers. One with a Young Mfg bcg & one with the Eisenach bolt carrier.

I have a Mega as well with the Young Mfg bcg.

I'm building a pistol build with the CMT upper.

The Lantac is probably my favorite. It works with any handguard & is built like a tank.
