JPSCS2-9SS-4/5K

9mm Short Stroke Conversion Kit
for JPSCS2-9 Silent Captured Spring

This 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 complete package includes the following:

• 5-mass slider
• steel mass
• 5x replacement o-rings
• snap ring
• spare buffer retention screw
• chamber flag
• instruction sheet

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 such as the GMR-15™. 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.

Compatibility

The JPSCS2-9SS-4/5K will only convert Gen-2 9mm SCS systems and is not compatible with Gen-1 SCS’s.

This unit is not compatible with other calibers beyond 9mm due to the different bolt stroke length.

See our FAQ section if you have more compatibility questions.
