FEATURES:

This system allows the shooter to have the equivalent of a bolted together upper and lower receiver group while maintaining the ability to quickly and effectively disassemble the firearm in a traditional manner through a simple thumb lever attached to a cam shaft.

Testing reveals up to half an inch of Minute of Angle improvement with certain upper receivers when attached to the USAC Cam-Lock Lower Receiver. You will not find a tighter receiver on the market.

Compatible with all Mil-Spec upper receiver groups, both piston and gas impingement systems for:

• AR-15
• M-16 A1A2
