Vltor MUR vs. Colt OEM upper

[BWT]

Colt uppers.

The FBI HRT makes due with theirs. Also, this isn’t a long distance gun - so to me, keep you lose the benefits of the MUR upper.

Thanks to everyone for the replies so far!

I'm sold on the Colt upper for the pistol, but am still about the SBR--at 33 oz. the 11.5" HRT barrel weighs as much as a 16" Gov't profile barrel, and the KAC QDC and MAMS will add another 21 oz. With that much extra weight will receiver flex be an issue where the MUR will provide a tangible benefit?

I don't think you'll see any benefit, and I'm still interested in your takeoff Colt barrel.

I haven’t forgotten about you 😝 I just have to wait for the SBR to get out of NFA jail before I can start swapping things out
