Details

The Auxiliary Spring Rate Kit for the JP Silent Captured Spring allows custom tuning of the device to a given rifle. While the default spring installed in the JPSCS is selected to offer the best performance for the widest range of configurations, a simple disassembly and reassembly of the JPSCS with a slightly different spring rate can yield truly optimized performance, particularly for rifles without an adjustable gas block. In selecting a spring for your rifle, install a heavier spring if you feel the buffer head fully compress and bottom out while firing the weapon. If the bolt carrier will not lock back reliably on the last round fired, even when completely gassed (in the case of an adjustable gas block), select a lighter spring. In particular, if you have an ambidextrous bolt catch extension installed (e.g., the Magpul BAD lever), this extra mass on the bolt catch, in combination with the faster bolt velocity using the SCS with a heavier spring, may cause the bolt to ride over the catch before it has time to engage. In this case, a lighter spring should remedy the problem.

good addition

by

If you have the captured spring, just get this too. Allows you to fine tune the cycling of your ar.

Timing your AR

by

This kit works well if you have no adjustable gas block. My gun is over-gassed and yellow spring in this kit slowed bolt down to give 330 ejection pattern. Also love the shot cycle now, solid thump, no twang after shot and does not beat up brass.

Must Have....

by

This is a must have,if you purchase the captured sprING system. It allows you to dial in the buffer system, and we'll worth the extra investment.

As Advertised

The pack gives you 5 options for spring weight. This is great for getting specific handloads to cycle properly. Glad I picked it up with the captured spring.

No more jingle! Only down side is spring set is sold separately, for the price I wish the optional spring kit came with it.

Seems to have solved my cycling issues...

by

A bit pricey for a pack of springs, particularly since I only needed / wanted 1. However it seems to have made a difference in my short gas system cycling issues. I did make a couple of other adjustments before I had a chance to test fire it, including a re-seat of the gas block and a very thorough cleaning.
