Been thinking about a pistol-caliber carbine, but didn't want to have to buy a whole new gun? With CMMG's 9 mm upper receiver and AR-15-based 9 mm magazines, you can keep your favorite lower.
If you own an AR-15, you probably have some spare parts lying around. Declutter by building those parts into a workable rifle—the results may surprise you.
From a single handguard, an entire AR-15 grows. And this one came together with a unique, all-FDE look.
