Are you looking for a versatile load that's entirely compatible with a standard AR-15 build? Then check out our comprehensive selection of .300 Blackout upper AR-15 build kits and elevate your standard rifle today. Compatible with almost every 5.56/223 AR-15 part, .300 Blackout uppers are becoming a popular choice among AR-15 enthusiasts. To convert your standard AR into a .300 Blackout rifle, it's as simple as swapping out the upper receiver. This upper is not only adaptable, but it's also powerful without a ton of space; they can reach peak ballistic potential from just a 9-inch barrel! If you're interested in our USA-made aluminum and steel build kits, but you're not ready to build it yourself, then don't worry - the professionals at Delta Team Tactical can assemble any kit for you at your request!
