What is the WOLFF - Rifle Length Reduced Power Action Spring?

High-quality, reduced power, action spring helps cure feeding problems caused by excessive bolt "bounce" in fixed-stock rifles configured for 3-shot burst or full-auto modes of fire. Helps shooters fine-tune action cycling for light, target/varmint loads in semi-auto rifles.


SPECS: Tempered, spring steel. Fits .223 cal. AR-15/M16 rifles with fixed A1/A2 rifle stocks. Not for use in adjustable stock carbines.

Fantastic Option for Undergassed Uppers
This spring was a quick fix for an undergassed up that kept short stroking and failing to feed. After installation the rifle cycled flawlessly.

Fixed Problems
My AR builds were having bad, weird problems with locking shut both with and without feeding a round. I tried changing buffers and BCG's. This spring fixed everything, and the ejection pattern is now 3 O' clock as it should be. Works great with mil-spec ammo M855 and a large variety of reloads. Spring is a little longer than some springs but made with a lighter gauge. Now my AR goes bang, bang, bang as it should.

It works!
I had problems getting my new AR-10(home built) to cycle. This spring fixed it and at the same time seems to reduce felt recoil.

Problem Solved
My M16 clone rifle was having issues with recycling and feeding. So I decided to give this reduced power spring a try and guess what? This spring cured the recycling and feeding issues on my M16. I shot about 60 rounds to test fire it and I had zero malfunctions. I was so relieved.
