This kit is perfect for those who are looking to utilize a Sig-Brace, or other standard aftermarket pistol tube braces/accessories. The KVP pistol kit utilizes a standard castle nut and end plate for attachment to a lower receiver. This attachment method does away with the need for a strap wrench.There are many ways to smooth the operation of a AR-15 Carbine. One of the most cost effective and quickest upgrades available, is installation of a KVP™ Heavy Tungsten Buffer. There are many added benefits once you install a KVP™ tungsten buffer. Benefits include: increased reliability, reduced wear and tear of critical internal parts, reduction in felt recoil, reduction in bolt bounce, as well as eliminating the annoying "rattle" of standard carbine buffers. Manufactured to meet the highest quality, KVP™ Heavy Tungsten Buffers are within a tolerance of +/- .005 oz, resulting in a more consistent, higher quality buffer.
Note: This tube doesn't work with the KAK Blade without modification.
