Jp jpscs2-15h2 silent captured spring ***wow*** - JP Enterprises Gen 2 Silent Captured Buffer Spring System

Running this on my MK18 10.3” that is suppressed full time. The MK18 is inherently violent out of the box. It was designed to eat anything and the designers erred on the side of caution in that it slams the round into the chamber with a vengeance ensuring reliability above all else. It is also notorious for premature breakages in bolt and carrier. If you’re shooting one that belongs to Uncle Sam, you can’t afford a failure but at least it doesn’t come out of your check. This one is mine and I’d like it to run fail zero. To get that done, I wanted to lighten the bolt carrier (added a JPBC-3A low mass bolt carrier with enhanced bolt) and move the weight into this JPSCS2-15H2 buffer assembly. This speeds the bolt up but, because it is significantly lighter, dramatically reduces the mass that normally ‘slams’ the bolt home. I also added a Superlative adjustable gas block allowing me to tune the entire package into what is the least violent, lowest recoil AR I have ever shouldered. If running unsuppressed, you would want to add a muzzle brake instead to achieve the same results. Followup shots are effortless. This setup is absolutely as good as it gets for a short barrel gas gun…period. Top shelf parts = top shelf performance and Optics Planet can’t be beat on price or service. A+++. As an aside, yes it is quieter than a mil spec buffer assy. THAT IS NOT WHY YOU SHOULD BUY THIS. IT’S JUST A PLEASANT SIDE EFFECT. BUY THIS TO REDUCE RECOIL AND IMPROVE RELIABILITY ON YOUR AR.
