JP Silent Captured Spring - for AR-15 with Fixed OR Collapsible Stocks - Gen 2

The new JP Silent Captured Spring system for AR-15 rifles and carbines takes smoothness and quietness to a new level for your AR15. 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 installed with the buffer retaining pin in place, but is far easier to install and remove for cleaning if you remove the buffer retaining pin from your rifle. This system has a super smooth feel to it and is great for suppressed weapons that need less spring noise. Works well in any AR-15 type weapon, but is best when used with an adjustable gas block so the gas and buffer can be tuned to perfection for the optimal feel.

Is proper length for AR-15 collapsible stock tubes. Includes a spacer to make it also compatible with fixed stocks.

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. Is not compatible with 9mm bolts.

Reciprocating mass is 2.7 ounces with the three 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.

a worthy evolution in AR buffers March 17, 2016
Reviewer: Paul M from Lone Star  
I installed one of the standard AR15 SCS units in my Fulton Armory Legacy carbine, (think Colt SP01) and it runs like a swiss watch.  This is a very mil-spec carbine, with a pencil barrel with a military sized gas port. It is less "gassed" than a lot of commercial barrels, as Gene Stoner intended. The SCS cycles perfectly, quietly, and as softly as can be expected with a carbine length gas system.  A captive operating spring is what every self respecting military firearm uses, now the AR system can have that virtue as well.

Second Purchase February 24, 2015
Reviewer: lee carter from mandeville, LA United States  
Purchased one almost two years ago and have no negative comments yet.  Notice improved cycle of the rifle and tighter shot groups during rapid fire exercise.  Ordered a second to install on a new rifle.  I would install in every AR platform I own.

Stop thinking about it and just order one! Now! February 16, 2015
Reviewer: David R from Sarasota, FL United States  
You can't even imagine how smooth and quiet your bcg will be until the first time you pull back on the charging handle.  If you see these in stock, order one.  If not, keep coming back until they have more.

And be sure you buy it from Para Bellum Products, the level of customer service I experienced through my many emails and phone calls was excellent.  Always patient, friendly and knowledgeable.  I will be back for more.  Thanks for all your help Brian, very much appreciated.

JPSCS January 2, 2015
Reviewer: Wayde Brozek from Wamego, KS United States  
I thought that it was a expensive product. I was having issues with my rifle short stroking and not picking up the next round. I had tried lighter buffers and springs and ended up shortning up a spring to get it to cycle. After reading these reviews I bought one. I will not buy anything else for future builds. Highly recommend!!!!!
