Finally, a simple, drop-in unit that will reduce the rate of fire in your M16/M4/AR-15 without loosing reliability. This new mechanical (not hydraulic like others) unit will automatically adjust to your individual weapon decreasing the rate of fire while increasing the accuracy potential. There are no special or weakened springs used with our system to interfere with feed reliability. Testing has shown rate of fire reduction of over 300 rounds per minute. Muzzle climb is drastically reduced meaning more rounds on your target. The faster your cyclic rate is, the more reduction you will see. During our testing, an 11.5" M16 with a cyclic rate of nearly 1100 rounds per minute was tamed by our buffer to function at 754 rounds per minute. We also tested the unit in an M16 with a 20" barrel that was cycling at 771 rounds per minute. It dropped to 585 rounds per minute with this new rate reducer and almost completely eliminated muzzle rise, even under full automatic fire! A D-fender D-Ring also comes with the MGI Buffer to virtually eliminate extraction problems.



First Impressions The first thing I noticed when I received the MGI Buffer was its weight. It's a little on the heavy side compared to a standard carbine buffer. With that said, the fit and finish is amazing, the buffer looks like it can withstand anything you through at it and then some.

Use The MGI Rate Reducing Buffer does everything it claims it solves. At first I was a little skeptical about its weight since my AR doesn't have any gas adjustment on it, so that I couldn't increase the pressure if it was being underpowered. But it worked perfectly with a standard carbine buffer spring, it drastically helped with my follow up shot in terms of muzzle rise. All in all its a great product for anyone looking to reduce their rate of fire or muzzle rise. MGI will definitely be a company I keep my eye on for my next AR build.
