Tactical Solutions ARU-SBX-9M AR-15 SB-X Conversion Upper Receiver Assembly .22 Long Rifle, 16.50" Barrel with 9" XG-Pro M-LOK Handguard, Black

The SBX upper for your AR-15 gives you a lightweight conversion allowing the user to attach a suppressor without significantly increasing the over all length of the rifle. The permanent shroud increases the barrel length so you won’t be swamped with traditional paperwork required when purchasing a short barreled rifle. The Tactical Solutions AR-15 SBX A3 Upper Receiver Assembly is a complete, dedicated rimfire conversion upper in 22 Long Rifle that is ready to install on any standard small pin lower receiver. It features a proprietary rimfire bolt assembly, true 22 LR chamber and correct 1 in 16" rifling twist, all of which ensure an accurate, reliable upper that is perfect for inexpensive practice, small game hunting, or introducing young shooters to the AR-15 platform. For useful, realistic sub-caliber training purposes, this upper offers the familiar operating controls and handling characteristics of a full power AR-15, but without the associated high priced ammunition.
