5.4oz AR15 carbine length buffer
SKU:
Buffer - 5.4oz
Adding to cart… The item has been added

Product Overview

This is a 3.25" long, 5.4oz steel buffer with "loose" internal weights that helps to keep the bolt closed and prevent bolt bounce. 

ATTN: We offer no guarantees that this 5.4oz buffer will fix your bolt bounce issue. If your weapon needs a 7+oz buffer in order to run, nothing less than the correct buffer weight will fix that. Most end users are using an H3/5.3oz buffer weight, but there is no way to know before test firing if you have the minimum amount of weight needed.  Rifle calibers besides 5.56/short barrels/short gas systems may require heavier than H3/5.3oz buffers. This buffer can be reconfigured with tungsten internal weights to achieve a heavier weight.

    I ordered this for a 7 1/2" pistol build along with Kit R -4140 super safety. So far it has been a great value for it's performance. Works fantastic. Customer service was excellent. Confirmation same day, tracking number the next day and package arrived a few days later.

    I have bought 4 of these now. All work extremely well. Dead blow buffers are necessary for AR pistols especially with the super safety. highly recommend
