We have found that the A5 buffer system makes for the most tunable, reliable, and smooth shooting system for typical AR-15 builds. Without detailed knowledge of a build, we recommend a "green" sprinco rifle length buffer spring and A5H2 buffer.
The A5 system is an innovative upgrade for the AR platform, increasing the reliability and performance of your weapon. It is proven in reducing cyclic rate, lowering bolt carrier velocity, and reducing felt recoil.
The RE-A5 Receiver Extension is a 7-position receiver extension tube designed to work with the VLTOR A5 buffer system. This receiver extension is slightly longer than the traditional M4 receiver extension and is designed to work with Mil-Spec dimensioned M4/AR-15 type collapsible stocks.
The RE-A5 Receiver Extension can also can be utilized as a replacement receiver extension for the AR-10 rifle when used in conjunction with a standard AR-15 Carbine length Buffer and Sprinco Red Spring.

-Internal of tube is dry film lube coated

-Space between the seven positions of the receiver extension: 0.650”
