You wanted to fine-tune your AR-15 9mm carbine so you changed the buffer. Good for you, you’re half-way there. That will take care of most of the problem, now you need to take the next step. You need to upgrade to a high-quality Kaw Valley PPC buffer spring.

All Springs Are Not Created Equal

There is a sea of replacement buffer springs on the market. To the naked eye, they look the same, but they’re not. Your eye can’t detect the tensile strength or resilience of steel, but the folks at Kaw Valley can. A KVP AR-15 9mm buffer spring gives you high quality at a low price. Their buffer springs are stronger, delivering a heavier preload for the weapons’ action. This is something that is easily overlooked, but critical when you want to dial in your AR-15 carbine.

Do Your Pistol Caliber Carbine a Favor

Your blowback AR will eat those expensive internal parts much faster with a low-quality buffer spring. You would much rather buy a high-quality KVP PPC buffer spring than a new buffer tube or bolt. When you throw a suppressor up front things get even worse. That’s when you really need a KVP AR-15 9mm buffer spring in there helping your weapon absorb the abuse. You want to live as long as you can and still perform, you really should put a top end PPC buffer spring in your AR so it can do the same. This just may be the only AR-15 carbine you ever have, it deserves a Kaw Valley Precision AR-15 9mm buffer spring. If you’re lucky enough to have a family of AR carbines they all want one, you do too.

    Did the trick 100% !! Replaced the 5.56 buffer spring on my PSA lower and I can finally enjoy semi automatic fire with my new KG 9mm upper. I couldn’t be happier!
