The Heavy Stainless Steel Tungsten buffer was developed for the 5.56 round, but it also works great in other calibers as well - Especially the popular Big Bores and 9MMs. These buffers weigh 6.5 ounces – More than twice the weight of OEM carbine buffers.
Features a Tungsten anti-bounce internal weight. Machined from solid 303 Stainless Steel and includes a Stainless Steel roll pin for a lifetime of trouble-free performance. The head is hand polished for an extra smooth finish that won't cause damage to your buffer tube.
An HSS buffer will increase reliability, prevent wear/tear on critical parts, and dramatically decrease the rate of fire in Full-Auto use. This product is great for the guys who switch uppers/calibers back and forth – It eliminates hassle of remembering to change the buffer.
Any serious carbine shooter can benefit from installing a HSS buffer. Your carbine will shoot super smooth with less felt recoil, and it will be easier to stay on target for fast follow-up shots. Sub-gun shooters, weekend warriors, 3-gun competitors, range commandos and serious operators all love the HSS Tungsten buffer.
Very effective with .223/5.56, 5.45, 6.5 Grendel, 6.8 SPC, .450 Bushmaster, .458 SOCOM, and .50 Beowulf. Can also be used with 9mm, .45 ACP, .40 S&W or 10mm.
This is the best all purpose Heavy Buffer on the market, Guaranteed. 100% Maintenance Free – No moving parts to break and no fluids to leak!
I recommend Wolff XP buffer springs for maximum reliability.
