Frequently Asked Questions
Will this barrel run both supersonic and subsonic 300 Blackout ammunition reliably?
Yes. The included adjustable gas block is key to reliable cycling across the full spectrum of 300 Blackout loads. Supersonic rounds typically require less gas restriction, while heavier subsonic rounds — especially when suppressed — benefit from opening the gas block further. The pistol-length gas system is well-suited to 300 BLK's pressure curve, and the M4 feed ramps support smooth feeding of both load types.
Is this barrel compatible with a standard AR-15 upper receiver and bolt carrier group?
Yes. This Odin Works barrel is designed for standard AR-15 platform upper receivers. It uses a standard barrel extension and M4 feed ramps, so it pairs directly with any mil-spec AR-15 upper receiver. You will need a 300 Blackout-specific bolt carrier group, as the 300 BLK uses a larger bolt face than 5.56 NATO.
What suppressor or muzzle device thread pitch does this barrel use?
This barrel features a 5/8-24 thread pitch, which is the standard for 300 Blackout and larger caliber muzzle devices. This makes it compatible with the vast majority of 300 BLK suppressors, muzzle brakes, and flash hiders on the market. Always verify your suppressor's thread pitch before purchasing to ensure a proper fit.
