Currently our R-10 Upper Receivers have a low profile picatinny rail.  In mid 2024, we will be transitioning our R-10 Uppers to high profile picatinny rails.  In the intervening time period, we will be producing both high profile and low profile R-10 Handguards.  Only our low profile R-10 Handguards are compatible with our low profile R-10 Uppers.  All current Rifles and Upper Receiver Groups will use uppers and handguards with low picatinny rails.  Once the changeover happens, all rifles and URGs will use components with high profile picatinny rails, and low profile components will be retired.

Weighing 6.8 ounces, the R-10 magnesium Upper Receiver is the lightest production LR308 upper receiver on the market. For use with large caliber barrels like .308 Winchester/7.62x51mm NATO and 6.5 Creedmoor, amongst others, this upper is compatible with DPMS GEN 1 compatible lower receivers. The R-10 is a low profile upper and is designed with an enlarged ejection port to ensure reliability and a quick detach dust cover that can be removed without uninstalling the handguard and barrel nut. Protected with Tagnite and Cerakote, the R-10 Upper Receiver is the best choice for your ultra-light weight large caliber AR build.

NOTE: ROAM Upper Receivers have an enlarged barrel pin slot to fit our Barrel Pin Clip. This eliminates the risk of damaging the upper receiver while torquing the barrel nut. You must use a Barrel Pin Clip to correctly install a barrel into our Upper Receiver. Every Upper comes with a Barrel Pin Clip.
