The USA Made 3.5" short buffer system transforms your AR pistol into an even shorter and more compact backpack gun. Other than a spanner wrench no additional tools are needed outside your armorer's tool box. Standard end plate.
New internals, new features, and a new look. Whether you're looking for a buffer replacement for your pistol caliber carbine, or your regular 5.56, 300BLK, or 7.62x39 AR, we have a short buffer system for you. We're breaking down the internals based on the two types of bolt carriers: integrated and non-integrated bolts. Integrated carriers have the bolt face machined directly into the carrier (common blowback 9mm, 40S&W, 45ACP, and 10mm carriers). Non-integrated bolts cover your typical 5.56, 300BLK, 7.62x39, and the CMMG radially delayed blowback calibers.
The 3.5 version will not require any modification to your carrier or end plate. Just install the short buffer system in place of your standard buffer, spring, and receiver extension.

converted all my braces to this Awesome buffer
F@@K the AFT
Ordered 2 and they arrived before expected. Loved them so I ordered two more. Due to parts issues, the shipment was delayed nearly two weeks, however, the customer service and communication was great. The live customer service is phenomenal. Highly recommend!
9 mm works perfect
Love the MCS Short 3.5" Buffer kit. Five stars for sure!!
Ridiculously fun. I paired this with a carbon fiber lower (WTH, figured I'd try it) and a PSA 7" Marauder. Everything functions and the gun runs like a top. CS is outstanding and quickly responds to questions. I'll be back.
Don't have many rounds thru it - they now come with a part not shown - to limit BCG movement - you need to adjust that for not more than about 1/8 play ! Important !
It runs better than my standard pistol buffer tube
So I have this I absolutely love it. I purchased a tail hook from gear head works to just give it a “finished” appearance and the cap doesn’t seem to fit in the opening. Is there another cap that might fit?
