Contrary to the original AR-15 rifle design, the LR-300 has the capability to use a fully folding and adjustable skeletal stock. Most AR-15 rifle variants have a thick, cylindrical recoil buffer tube, more properly called the receiver extension, that protrudes approximately 20 cm (7.9 in) straight back from the rear of the receiver, and the ...

The rear includes a H3 Buffer Tube which supports most AR stocks but comes default with a VLTOR E-Mod stock. [1] The barrel is 16 in (410 mm) in length. It is internally chrome-plated, with progressive 1/7 right-hand parabolic twist rifling. [12]

This type of buffer cushions the battering force of repeated metal on metal impact, reducing wear on parts and lengthening the service life of the firearm.

A M231 FPW, with wire stock (Top-right of the image) The M231 is different in many ways from a standard M16. The original Rock Island Arsenal FPW fired from an open bolt, with an extremely high rate of firing (1,200 rpm). The Colt XM231 introduced a special buffer and spring assembly, with three springs nested one within the other.
