The "Workhorse" represents our best effort to over rock solid reliability at the most modest price possible. By focusing the most on the critical components of the upper (barrel, bolt carrier group, and gas system), and using more modest "milspec" components where it matters less (forward assist, dust cover, charging handle, and upper receiver), this upper paired with a quality lower should be one of the best values available.
Whether you're looking for your first quality rifle, or something to recommend to a buddy, the specs on this package are hard to pass up.
Rosco Bloodline 16" barrel - true 5.56mm chamber, mid length gas system, nitride treated inside and out, factory dimpled for the gas block set screw with 1/2x28 threads.
Sons of Liberty "Capable" Bolt Carrier Group - Carpenter 158 bolt (HP and MPI tested), 8620 carrier steel, Sprinco 5 coil extractor spring, OCKS carrier screws, proper staking, laser etched cam pin for consistent orientation confirmation.
Sons of Liberty Gunwork Gas Block and Gas Tube - parkerized finish gas block with tight tolerances for a perfect gas seal, paired with a Melonite treated gas tube for reduced wear against the carrier key.
White Label Armory Upper Receiver - 7075 T6 aluminum milspec flat top upper receiver.
White Label Armory small parts - dust cover, forward assist, A2 flash hider and charging handle.
White Label Armory 13" MLOK Handguard - 7075 aluminum barrel nut, MLOK compatible sides with continuous 1913 picatinny top rail.
Each upper is inspected for its gas port size, bolts headspaced to the barrel, feed ramps polished, barrel nut properly greased and torqued to spec, gas block set screws are properly torqued and secured with Rocksett, gas block pinned for added security, then test fired with .223 and 5.56mm pressure ammo on a milspec lower receiver. Each upper ships with a spec sheet outlining all components used, and methods applied during assembly, so you know your upper receiver group is ready to go right out of the box (just add lube!).
These upper receivers are built to order. Please allow 1-2 weeks for delivery.
Feel free to add any preferred small parts to your cart to be incorporated into the upper (charging handle, muzzle device, forward assist, etc).
