Does anyone know if the remdef R10 handguard requires a proprietary barrel nut? Looking at buying a handguard but it wouldn't be worth it if I can't source the proper barrel nut and screws. Thanks in advance!
They’ve had at least 2 different handguard designs for that blaster, so you would have to pull the handguard off and take a look at it.
The R-10 is basically a militarized DPMS G II, so whatever is available for the G II should be compatible with the R-10. There are several different handguard options in the aftermarket that DPMS coordinated with before they released/revealed the G II at SHOT.
