JP Silent Captured Spring - for AR-10 with Fixed OR Collapsible Stocks

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 seperate buffer is needed. Additionally, the system includes a large 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 perfectly 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.

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 rifles with the smaller bolt carrier hole, some of the newer ones will work (check diameter of hole vs. .450" diameter of rod. Will not fit the Rock River Arms LAR-8 or pre-2010 Bushmaster .308 due to longer bolt carrier lengths. May not lock open on last round on Colt 901 rifles unless you use the alternate JP spring pack.

Reciprocating mass is 3.1 ounces with the two steel weights that come on it. Replacement tungsten weights are available separately if you desire to increase the mass. Replacement spring packs with different weight springs are also available separately.

Captured Spring June 10, 2014
Reviewer: james taylor from freeport, FL United States  
I added this to a build I was doing and am very happy I did. Fit and finish is very smooth and sturdy. I put it in a rifle length buffer tube and had to use the white extension piece that it came with. The captured spring does its part in reducing felt recoil and would serve well as a upgrade or an addition to a new build. Just make sure if it is a new build do not use the buffer retainer pin.
