JP Enterprises 9mm AR Full Stroke to Short Stroke Silent Captured Spring Conversion Kit

The JP EnterprisesA(R) 9mm AR Full Stroke to Short Stroke Silent Captured Spring Conversion Kit allows the changeover of any existing Gen-2, 4-mass 9mm Silent captured Spring (JPSCS2-9) to a 5-mass short stroke version. The 9mm Short Stroke Version provides the same reliable buffering as our other 9mm SCS models but with a shorter overall stroke. Designed for competitors looking for every edge, this model offers snappier cycling with even less felt recoil thanks to the shorter stroke. Note that because of its shorter travel, a short stroke Silent Captured Spring will not actuate the bolt catch on 9mm carbine receivers unless you have the current version of our 9mm bolt assembly. But, as our PCC stars always say, if you run your mag. empty at a match, you've done something wrong. Plus, the superior cycling more than makes up for it. This kit includes a 5-mass slider, steel mass, 5x replacement O-rings, snap ring, spare buffer retention screw, chamber flag, and instruction sheet.
