This is what we know about the RGP upper so far,
- 1-piece monolithic upper, handguard has multiple QD sling points and the rails are modular,
- Push-pin release, self-adjust gas piston system,
- AAC black out flash suppressor for mounting sound supressor
- barrel: hammer-forged, 1:7 twist, 6 groves and free-floated; barrel can be changed out with an allen-key. Currently available for LE in 10.5 and 14.5 configurations,
- 5.56 for now, maybe 6.8 down the road,
- works with any standard AR lower
- full rifle: 10.5 is 6.56 lbs, 14.5 is 6.95 lbs
The good news, the upper will be available for civilian sale (finger-crossed, by the end of the year according to Remington reps). Maybe a non sound-suppressor ready AAC black-out flash suppressor and 16 inch barrel for the Canadian market?
