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 or new 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.
The Forged 7075-T6 A3 Upper comes equipped with a Flat-Top Picatinny Rail for mounting optics, 16.5" Chrome Moly Bull Barrel, 9" XG-Pro M-LOK Free Float Aluminum Handguard, functional ejection port door and charging handle. One 25-Round Black Dog Magazine is also included. This upper is compatible with Black Dog Machine and CMMG rimfire magazines, and is 22 Long Rifle specific, meaning the upper cannot accept bolts, carriers or barrels in any other caliber. Different handguards designed for centerfire AR-15's are compatible.
