I received my JP Enterprises Silent Captured Spring & Buffer last week. Unlike most new products I test I stuffed this one directly into my match gun and drive two hours both ways to a monthly 3 gun match to test the system. I had quite a bit of confidence in the new system based solely on the company manufacturing it. The new JP Silent Captured Spring & Buffer did not disappoint!

I fired about 75 rounds through my Stag Arms Model 3G at the match. There was a good mix of fast CQB type shooting and slow fire long range shooting. We also saw our fair share of dust and wind. None of it was any trouble for the JP Spring.

When I first installed the new spring into my rifle I remembered that you do not need the buffer retainer for this unit. It will not fly out of the gun without one which is really cool because I know one day during a rifle build or stock change I am going to lose an eye from the buffer retainer pin flying up and hitting me in the face. Installation was quick. I run a stock with a rifle length buffer tube I had to first drop the nylon spacer into the buffer. Getting the new spring kit into the gun would have been mindless had there been no buffer pin in the rifle. But since my rifle still has one I had to do a little wiggling and pushing to get the buffer weights past the pin. It was also easier to install when I took the upper half completely off of the rifle. Once installed, I racked the bolt a few times. WOW, talk about smooth!!! The friction is minimal. It made my current JP Enterprises custom carbine center-less ground and polished operating spring and low mass buffer seem less awesome than they are which is hard to do. The new silent spring setup did feel as though there was more spring tension than my regular JP buffer/spring setup. I would expert John Paul has the spring rate dialed right where it needs to be though as the gun ran like a champ all day.

I had completely forgotten about the fact that I had installed the new system when I broke my first shot at the match. I was shooting prone and my compensator was between a dump barrel and a tree on dry dirt. The compensator immediately created a dust storm in my shooting area and that coupled with this odd quiet smoothness to my rifle had me confused briefly that my rifle might have suffered a malfunction. I didn't feel the bolt stop and my trigger reset so I squeezed off my second round. I was dumbfounded. I typically double plug when I shot utilizing foam ear plugs inside my Peltor Tactical Sport amplified muffs which deadens everything. I thought man these plugs are workign great today. The 2nd shot it took felt the same and felt and sounded kind of like shooting a suppressed rifle with muffs on. The best way I can think of to explain it is very uneventful. Immediately after the 3rd round I fired I realized what was wrong with my rifle. It was running better than it ever had before!

Here are some cell phone pictures of the system next to the one it is replacing in all of my rifles.



The new Silent Spring & Buffer does weigh almost twice what the previous setup weighs as can be seen below. This is about the only downside to the system I found and that is only a negative if you are carrying your rifle all day.






Here is a video from the match this weekend.

Thanks for the review. Looks like I too will be getting one of these. I've been looking for a good write up.

I talked to Ben at JP last week when I placed an order for a few things. He said they they were looking at 6-8 weeks out. They didnt expect to sell out as fast as they did.

Thats subject to change of course.

Ordered mine today!!! Seems to be the cats meow.

Anyone have a problem with the bolt locking back on the last shot.

Jesse, did you really appreciate a performance improvement based on the addition of this buffer? Did your times improve or accuracy of follow-up shots change at all? I agree a quieter buffer assembly would be nice, but I am on the fence about the double in weight if there is no real appreciable improvement in how the rifle performs.

I have done atleast 6-8 mag changes on empty and no lock back.

Not on the gun that it installed in right now, but I have another rifle that has a JP adjustable gas block. I may switch it out just to see if I can get it to work.
