Let's build an extreme use AR-15 (UPDATE PAGE 8 & 9)

[Army Chief]

Pardon me if I've missed something along the way, but how is an Afghan barrel compatible with a LMT MRP upper? It was my impression that only the VLTOR VIS allowed the use of standard barrels, whereas the LMT requires proprietary modifications in that regard.

For this reason, among others, I would favor the VIS if a mono-/polyithic upper was to be selected.

You didn't miss a thing! I did! I wasn't very thorough and forgot about their barrel mods. I stand corrected, thanks AC

The LMT MRP does use propriertary barrels, but they have such a wide selection now that it no longer a negative against the MRP.
