JP Silent Captured Spring - for AR-10 w/ Fixed OR Collapsible Stock - Gen 2 Heavy

This is the Heavy Version of the JPSCS2-10 which has more mass than the standard version. We now carry the latest Gen 2 version of the heavy AR-10 system with H2 weight of 4.4 ounces. Uses 2 tungsten weights and 1 steel weight and shorter rear bumper. The new JP Silent Captured Spring system for AR-10 rifles and carbines takes smoothness and quietness to a new level. This system consists of a smaller diameter recoil spring captured on a guide rod to totally eliminate the contact of the spring with the buffer tube and the spoon on a cheese grater sound. The buffer weights are also integral to this captured system so no separate buffer is needed. Additionally, the system includes a synthetic buffer to cushion the impact at the rear of the recoil stroke. Furthermore, due to its captured design, the need for the buffer retainer spring and plunger is eliminated. It can be used with the buffer retaining pin in place, but is far easier to get in and out if you remove the buffer retaining pin from your rifle. Works great with fixed gas systems, but at its best when used with an adjustable gas block so the gas and buffer can be matched for optimal performance and feel.

Fits AR-10 rifles with collapsible stock tubes (7" internal length) that use the short 2.5" buffer. Can fit AR-10 rifles that use the 3.25" buffer if you modify the spacer to be 3/4" long and use it. Fits AR-10 rifles with fixed stocks using the included spacer.

Reciprocating mass is 4.4 ounces. Replacement steel and tungsten weights and spring packs with different weight springs are also available separately.

Recommended Applications: Short Barreled Rifles (SBRs), Suppressed Weapons, Select Fire Rifles, Piston Operated Rifles, and any system that recommends an H2 buffer weight.

Compatibility: The JPSCS2-10 is not compatible with the HK MR762, the Sig 716, or the Rock River LAR-8 due to the longer bolt throw of these rifles. May not lock open on last round on Colt 901 rifles unless you use the alternate JP spring pack. The Guide Rod in the JP Silent Captured Spring extends into the rear of the bolt carrier as it cycles. The head of the guide rod is .450" in diameter. It is NOT compatible with any bolt carrier that does not have the normal size hole in rear of the carrier to allow the guide rod to cycle. Will not fit PWS Pistol rifles with the smaller bolt carrier hole, some of the newer ones will work (check diameter of hole vs. .450" diameter of rod.

Decreased felt recoil, decreased time to re-engage for second and third round shot. Does what it says it does.
