Product Info for Jacob Grey Firearms 7.62x39 Cal Complete Upper Assembly
One of the best things about the AR-15 platform is the versatility it offers. Shooters can easily adapt to various scenarios and situations from a singular platform without the need for investing in completely new firearms. Switching out the upper assembly of an AR-15 can add new calibers, barrel lengths, and configurations in a short amount of time. Which is one of the reasons why Jacob Grey Firearms developed its AK variant of the AR-15. With the popularity of the 7.62x39 round it only seemed liked a natural progression for Jacob Grey to delve into the round where others fear to tread!! Several features on the JG-47 Upper receiver that we changed from a standard AR-15 Upper receiver are reinforced extractor on the BCG bolt, the power of the 7.62x39 round tends to put excess wear and stress on the standard extractors, so with reinforcing the extractor the shooter has less chance of malfunction. We use enhanced firing pins to make sure a solid connection is made to the primer of the 7.6239 round. Heavy or HBAR barrels to withstand the explosive force behind these rounds, plus we recommend using a H3 buffer, so the shooter has a full cycle each time the trigger is pulled. And as all Jacob Grey Upper Receivers are manufactured from Billet 7075 Aluminum it only stands to reason that the JG-47 Upper Receiver will withstand everything the 7.62x39 round will throw at it for years to come. This upper receiver also includes the JG 7075 billet machined aluminum dust cover which gives this Upper Receiver a sleek perfectly matched look that would be a worthy addition to any quality build. The Jacob Grey Billet Aluminum Upper Receiver features a No forward assist function due to the exacting tolerances and reliability of its functioning.
To prevent any confusion, the purchase of all Jacob Grey Complete Uppers includes the Jacob Grey ambidextrous charging handle & F/A rated BCG.
NOTE: Complete uppers with barrels under 16 in length are only for use on AR-15 pistol lowers, legal Short-Barreled Rifles (SBR).
DISCLAIMER: Firearm specifications are subject to change at any time based on availability and supply chain shortage.
