Frequently Asked Questions
Will this end plate fit my AR-15 buffer tube?
Yes. The B5 Systems QD End Plate is designed to fit standard mil-spec AR-15 and M16 buffer tubes. It installs in place of your existing end plate and is compatible with standard castle nuts, which should be staked after installation for a secure, permanent fit.
What type of sling is compatible with this end plate?
This end plate features a single QD (Quick Disconnect) swivel socket, making it compatible with any standard push-button QD sling swivel. It is primarily intended for use with single-point slings, though it can also serve as the rear attachment point for a two-point sling configured with a QD connector.
Does the QD socket rotate freely or is movement restricted?
The B5 Systems QD End Plate uses a limited-rotation design rather than a fully rotating socket. This controlled movement reduces unwanted sling shifting during use while still allowing enough play for comfortable carrying and quick transitions — a deliberate design choice favored by tactical and duty users.
