LMT has gas piston complete uppers now and they're supposed to be very good. They also have a conversion kit but I can't find any info on it. Does anyone know what uppers the conversion kit will work with?
Just my opinion... anything LMT is of high quality, BUT, for that kind of money, I'd buy a SIG 556. Or buy another AR + mags and ammo. The piston conversion kit is for the standard DI MRP uppers.
