The Luth-AR Double Tungsten H2 Carbine Buffer (brand part no. CS-T2) is a heavier-than-standard AR-15 buffer built for .223/5.56 carbines running shorter gas systems. Luth-AR packs two tungsten slugs and one steel slug into the buffer body for a total weight of 4.8 ounces, slowing bolt-carrier velocity to improve reliable cycling where a standard-weight buffer runs too fast. Shooters running shorter gas systems or heavier ammunition often notice a reduction in felt recoil as a side benefit. Among AR buffer systems, this H2 buffer favors builders tuning reliability on carbine-length and mid-length gas guns.

Frequently Asked Questions

Why use an H2 buffer instead of standard weight? The added tungsten and steel mass slows bolt-carrier velocity, which helps reliable cycling on shorter gas systems.

Will this fit any AR-15 buffer tube? It’s sized for a carbine buffer tube only, not rifle-length or pistol tubes.
