Product Details
This is a complete upper receiver ready to drop onto your AR-15 lower, built around 300 Blackout - a cartridge that's quieter and hits hard, especially if you're shooting suppressed. You get a 9.75" barrel with a 1:8" twist rate that'll stabilize heavier bullets, paired with PWS's Triad muzzle device and an 8.9" handguard with plenty of mounting spots for lights or accessories. The Radian Raptor charging handle works smoothly from either side, which is nice if you're still figuring out what feels natural. It's a solid, no-nonsense build that works just as well for someone learning as it does for someone who's been doing this awhile.
