Frequently Asked Questions
What is the difference between an A5 receiver extension and a standard carbine buffer tube?
An A5 receiver extension is slightly longer than a standard carbine tube and is designed to work with A5-length buffers and springs. This system allows the buffer to travel farther during the cycling stroke, which reduces felt recoil, lowers bolt carrier velocity, and can improve reliability — especially on suppressed builds or rifles running mid-length or rifle-length gas systems. The Loyal 9's 9-position design also gives you three additional stock positions over a traditional 6-position tube for a more dialed-in fit.
Will this receiver extension work with my existing AR-15 stock and lower receiver?
The Loyal 9 A5 Receiver Extension is compatible with standard AR-15 mil-spec lower receivers. However, because it is an A5-length tube, you will need a stock that is compatible with A5 or carbine-length buffer tubes — most standard mil-spec carbine stocks will fit. Note that you should also pair this extension with an A5-compatible buffer and spring for optimal function. It is not compatible with AR-10/LR-308 platforms or pistol lower receivers requiring a pistol-length tube.
Do I need to replace my buffer and spring when installing this receiver extension?
Yes, for best results you should pair the Loyal 9 A5 Receiver Extension with an A5-length buffer and an appropriately rated A5 spring. Using a standard carbine-length buffer in an A5 tube can result in feeding and cycling issues due to the difference in geometry and travel distance. Sons of Liberty Gun Works and other reputable manufacturers offer A5-compatible buffer and spring kits that pair perfectly with this extension to create a smooth, reliable operating system.
