I have three of these for sale. I have found this combination to be the smoothest option out there, but I have run out of lowers that need them. I've run this combo in 11.5 and 14.5 KAC uppers using weaker .223 ammunition and still have flawless function, and they still feel amazing with full power MK262 etc.
These buffers are used, and show signs of it. The springs are relatively new, no more than 1500 rounds on any of them....however with their tested lifespan, I suspect by the time round count is an issue, you'll be on your 5th or 6th barrel.
The one with minimal wear on the face with all markings clear and legible is 110 shipped.
The two with wear on the face with the black coating worn are 100 shipped.
Paypal FF/Zelle preferred.
Not looking to separate; if you've never tried a Tubb spring, especially in a KAC, you will absolutely LOVE the pairing.
