Rifle Buffers
KynSHOT AR-10 Shorty Buffer – RB5004
Out of stock
$129.99The KynSHOT RB5004 “Shorty” Recoil Buffer is designed for AR-10 carbines with a collapsible stock and an AR-15 length (7.0″) buffer tube which is common on many AR-10 applications.
- Weight: 3.8 Ounces.
- Length when Compressed: 2.5″ and replaces buffers that are 2.5” long.
- Mil-Spec Hydraulic Fluids and Seals – Ambient operating temp certified for -30F – +150F
- DO NOT USE IN 9mm AR-15s. For 9mm AR15s use KynSHOT P/N RB5007, RB5015HD or RB5020SS. See Selection Matrix for proper buffer choice.
- Designed for 7.62mm/.308 cal. AR style rifles with an M4 length buffer tube (which is 7” deep, and ¾” shorter than an Armalite AR-10 collapsible stock tube). This is a common factory stock arrangement on many factory
- .308 rifles such as DPMS, CMMG and many others. The best reference is that it replaces factory buffers that are 2.5″ in length.
- Also works well with other calibers based on the .308 case such as the .338 Federal, .260 Remington and .243 Winchester if they have the M4 buffer tube. If you buy an aftermarket AR-15/M4 collapsible stock tube for your
- .308 AR, this is the buffer you will need. The Magpul UBR stock also uses an AR-15 carbine length stock tube and would also require this buffer if used on a .308 rifle.

- Designed for 7.62mm/.308 cal. AR-10 type rifles with an AR-10 length collapsible stock buffer tube which is 7 3/4″ long on the inside (AR-15 collapsible buffer tubes are 7″ on the inside). The best way to confirm is to measure the length of the buffer that came with the rifle from the factory.

Geissele Automatics Super 42 Braided Wire Buffer Spring and Buffer Combo
In stock
$75.65 – $110.47The Geissele Super 42 Spring was designed to improve the function and reliability of your AR-15 pattern rifle. Its unique spring design uses three independent strands of wire, just like the German MG42 Machine Gun. This concept acts as a harmonic damper and energy absorber by allowing the springs to flex separately from each other. This flex helps displace excess energy which decreases the chance of spring failure and assists with making your AR-15 more reliable.
- Compared to the stock spring, The Geissele Super 42 Spring has a decreased tendency to lose length and force over a given round count. As an added bonus, it removes the annoying spring reverberations (twang) heard and felt by the shooter through the buttstock.
- The Super 42 Spring has a 15% stronger average return force than the standard buffer spring. This will assist in stripping rounds out of the magazine when operating with a dirty weapon or when using steel-case ammo.
