Our DSG complete 8” 300BLK utility grade upper receiver with 7” BCM M-Lok rail is the perfect solution for your rifle. Our upper receiver, designed from 7075-T6 aluminum with type III hard coat anodized, will last you several years.
Complete Upper Features:
Upper is Mil-Spec upper receiver with M4 feed ramps. CNC Machined of 7075-T6 Aluminum, Type III Hard Coat Anodized. Barrel is 4150 chrome moly vanadium steel with 1:7 twist, 8.5″ heavy profile, button rifled, pistol length gas system, QPQ coated barrel extension, with A2 flash suppressor and crush washer. Barrel has been dimpled to ensure gas block does not move.
To ensure a long lifespan for our barrel, we have created it using 4150 chrome moly vanadium steel to prevent corrosion. We have not added a dimple to our barrel because we want to reduce manufacturing costs and lead times and offer you an affordable product. We have added a gas block seat to our barrel to prevent bending, reduce overheating, and improve stabilization.
Our complete package also includes the BCM M-lock rail, which comes with a compatible mounting system, free float handguard to eliminate loads for the barrel, reduce deflection, and improve shooting accuracy and precision, and hard coat anodized for improved lifespan.
Other features of the barrel include precision machined 6061-T1 aluminum alloy to increase strength and decrease weight, propriety engineered profiles to improve cross sectional strength, and steel barrel nut to mitigate movement under heat.
You also receive one nylon picatinny rail section and QD sling attachment. If you are searching for a product that comes with a barrel, upper receiver, and rail, you have found it!
