Note: This upper receiver features a barrel shorter than 16" and is subject to all NFA rules and regulations as well as your local laws. Must be attached to a pistol lower receiver or registered SBR lower.
An increasingly popular configuration for the AR-15 is as a 7.5” pistol, but picking the right upper can be tricky. Because the gas system is so short, some shooters build their own 7.5” AR pistol only to find that it does not reliably cycle. In this case, it’s easier to go with a complete upper receiver to get the manufacturer’s assistance.
Tiger Rock has made a very affordable option for those looking to start a basic AR-15 pistol build. Featuring a 7.5” barrel with a 4” M-Lok Super Slim handguard, shooters will be surprised to find how light and maneuverable this upper can be when paired with a solid pistol lower receiver. If you already have a pistol lower, this upper receiver will give you everything else you need, aside from a set of sights (or optic, you so choose).

This upper receiver includes a US-made black nitride bolt carrier group, a stainless-steel pistol-length gas system with low-profile steel gas block, and a tactical charging handle assembly. The muzzle is threaded for standard ½”x28 and includes an attached A2 flash hider, which is great for short-barreled pistol builds. The barrel is a Chrome Moly Vanadium steel with 1:7 twist rate—perfect for the heavier bullets, which do well in short barrels.

Exposing the gas block is a great idea, what could go wrong?
