Strikefire Industries Carbine Flat Wire Buffer Spring

I have a few installed and so far I like them quite a bit. They're around $20 and nicely get rid of the TWANG!

Agreed, I'm running two of them and they're quieter than standard carbine springs.

I’m funny that way, I don’t notice the twang on any of my gas guns. My JustRight Carbine in 9mm on the other hand is very noticeable. Probably because it’s a straight blow back design.

If you have twang going on... make sure the interior of your buffer tube is smooth. I have seen some pretty rough ones.

Also a light coat of grease, on the recoil spring will help twang.
