Osprey Piston under a VTAC Modular Handguard?

BTW... the LMT MRP is a complete upper system developed by Lewis Machine Tool. Here's a link:

Indeed, the MRP is not compatible with the VTAC because the upper receiver and handguard are all a giant single piece of aluminum. This obviously gives superior strength and rigidity. ETA, but one of the extremely groovy things about the MRP is is that you can (relatively) quick-change barrels on it. Allowing you to run multiple barrel lengths or multiple calibers in the same gun (although the alternate barrels available are fairly limited selection-wise from LMT).

Here I am looking for a Magpul Moe handguard to fit

Easy fix. Take that shit off, throw it in the trash. Then put the gas tube and proper carrier back in.
