There are a lot of choices out there for .22LR rifles in all kinds of configurations. But we were looking for a bit more. This is a premium grade .22LR upper with a threaded 16.5: aluminum barrel with a stainless liner that has a match chamber. The upper reveiver is a standard mil-spec unit fitted with a .22LR bolt assembly. The Carbon Feather handguard keeps the weight down and the speed up. Depending on sights and lower, 3.5 to 4.5 pounds is where you will be. The big difference with this unit...accuracy! Using even bulk pak ammo, this upper delivers smaller groups than its competitors while maintaining exceptional reliability. Intended for use with your complete lower and Black Dog style .22LR magazines.
NOTE: Not all trigger systems will provide 100% reliability. Some heavy hammer spring triggers take too muich energy out of the blowback system to function properly. Some tuning to your lower and mag catch may be needed.
