The Super Dynamic (SD)triggers have the same body geometry as the SSA models and feature a flat trigger shoe that reduces perceived pull weight, improves control, and gives excellent tactile feedback. Super Dynamic Combat (SD-C) trigger has a 2.5 lb. first stage and a 2 lb. second stage for a 4.5 lb total pull weight with a sharp, repeatable trigger release. Super Dynamic Enhanced (SD-E) trigger has a combined 3.5 lb. total pull weight, with a 2.3 lb. first stage and a 1.2 lb. second stage. Super Dynamic 3-Gun (SD-3G) single-stage trigger has 3.5 lb. pull weight with a short pull length and short reset - excellent for fast-action competitions.

SPECS: Steel, black finish. Fits semi-automatic AR-15/M16 receivers with .154" diameter hammer and trigger pin holes. May be installed in AR-style .308 rifles that accept AR-15 triggers. Does not fit HK416 weapons with firing pin safety. Kit includes trigger andhammer assemblies, springs, hammer pin, tube of grease, and illustrated instructions.
The Gen 2 Drop-in captured-spring recoil system helps your AR function more smoothly and quieter without any permanent modifications. The carefully balanced, custom-ground buffer spring, combined with the JP LMOS buffer, greatly reduces friction and vibration - say goodbye to the annoying “spoon over a cheese grater” noise of conventional springs and buffers. Fits buffer tubes for both M4-style collapsible stocks and also, using the included spacer, the longer tubes for fixed rifle stocks.
The Auxiliary Spring Rate Kits for the JP Silent Captured Spring allow custom tuning of the device to a given rifle. While the default spring offers 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.
Benefits of the Gen 2 Captured Silent Springs include:
New aluminum guide rod cuts overall weight
Comes with three stainless steel weights
Heavier masses translate to more buffering mass and chance of bolt bounce
Full correspondence between SCS masses and H1, H2 and H3 buffers
Interchangeable buffers allow conversion between AR-15 and AR-10 models (and vice versa)
Includes spacer to allow for installation in both carbine-length and rifle-length buffer tubes, as well as three stainless steel weights. The standard weight buffer weighs approximately 3.0 ounces.
