BROWNELLS - BRN M4 Buffer Springs, Stainless Steel, 1 Pack

It arrived in easy to open packaging and great to keep around as spares.

These springs work, feel good and are as good as any spring I've felt and used. They are better than what I was using which was so heavy I could hardly pull the charging handle. These work well.

I bought a pack of these because I built a couple AR pistols with Crane Spec gas ports and I was having cycling issues using the enhanced JP enterprises springs and a Primary Weapons H2 buffer. These springs and a standard M4 buffer solved my issues. The quality is nice and would be good for most standard builds.

10.75 inches length. Perfect for replacement or new build. Milspec.

I give these out as gifts to my good friends. The CS M4 carbine buffer spring is a true std power spring. I had a buddy with a DD lower who only had 3000 rounds through his spring. I gave this to him, he dropped it in and immediately noticed that it was stronger than his buffer spring. The thing is, it's NOT stronger, it just doesn't fatigue like normal spring steel. Chrome Silicon is the FUTURE in gun springs. There is a reason ALL heavy duty extractor kits include a chrome silicon extractor spring. His spring had already become noticeably weaker in 3K rounds. I have several buddies who are right at that mark with ZERO reduction in spring strength compared to a fresh Brownells CS buffer spring. Unbeatable price. ESPECIALLY for agency armorers. A stronger buffer spring equals a smoother recoil impulse, more reliable extraction, and more reliable feeding into a dirty chamber. There is no downside for this price!!!
