I’ve been known to tinker and tweak my guns until I get them running perfect. One of the AR’s I’ve done this the most on is my Quarter Circle 10 9mm. The blowback operation of these 9mm guns creates a ton of energy and gets the BCG moving at a very high rate creating a lot more felt recoil than you would ever guess and can also lead to beating up and breaking parts like bolt catches, etc. I’ve mostly been swapping around different springs and buffers going heavier and heavier.
KAK Industry just rolled out a brand new 9mm Configurable Buffer Kit that lets you swap out weights inside the buffer to adjust the overall weight of the buffer in stages up to 10 ounces.
This new KAK 9mm Configurable Buffer Kit would have really come in handy while I was trying to figure out the perfect buffer weight to get my build running like a sewing machine. It is also perfect for making adjustments for Suppressed, UnSuppressed, Subsonic Rounds, Full Auto, etc. If you’re tweaking your AR9, you definitely need to check out this new 9mm Configurable Buffer Kit from KAK Industry.
