Easy install. Helped with my tight lock up. Have not shot with it yet.

Would not use.

I installed JP buffer spring after a barrel change (old OEM spring had 4000 rds on it). Would not work, did not pick up next round from magazine. Try all my magazines and adjusted gas full on and still did not work. Installed old spring and running like it should.

Great Product. Highly Recommend!

I used this for an Aero Precision M5 build. I have a Magpul PRS on a Double Star fixed buffer tube, DPMS rifle buffer and a Bravo Company charging handle. Im not sure if its just the combination of all of those things together but you literally CANNOT hear the spring when pulling back the charging handle, its very smooth. Makes shooting quite pleasant without the crunchy, ringing sound of a cheap spring. I have never shot a JP silent capture but I don't feel that it is worth $100+ when you can just drop $20 on this and it works just fine.
