A few months ago we showed you the recoil reducing buffer from MGI for the AR-15. The .223/5.56 AR-15 doesn’t really have that much recoil to reduce, but every little bit helps. Shooters looking for tighter follow up shots, or lucky owners of a fully automatic AR-15 have claimed that such buffer upgrades increase accuracy greatly; however, that wasn’t the reason the MGI Buffer caught my attention.
My AR-15 was having trouble cycling correctly while shooting it suppressed–the increased gas pressure due to the suppressor was causing my bolt to cycle way too fast. It was so fast, that my brass did not have ample time to eject. I confirmed this by first replacing my extractor and spring on my bolt (start with the cheapest part first for troubleshooting right?). This didn’t help, all my brass was still getting caught up as seen in the video below. I had three options to get my AR-15 cycling correctly: I could get an adjustable gas block; I could change my DI gas system into a piston system; or I could try a cyclic reducer. I chose the easiest and cheapest option–the MGI Recoil Reducing buffer.

The installation of the the MGI Buffer is the second only to the magazine for least effort required. Simply open up the lower receiver, pull out buffer spring, and replace the buffer.
There are other replacement buffers on the market, and while their purpose is essentially the same, their construction is not. The others feature a hydraulic system to absorb the recoil of the bolt while the MGI buffer is completely mechanical which isn’t prone to leaks as other have reported with the hydraulic buffers.
After about 3,000 rounds through my AR while using the MGI Recoil Reducing Buffer, it hasn’t failed on me yet. More importantly though, it completely solved my spent cartridge ejection problem I was experiencing while shooting suppressed. It seems that the MGI Recoil Reducing Buffer slowed the bolt down enough so that the spent casings could exit the receiver reliably and consistently.
Well MGI’s buffer solved my problems, but not everyone has this problem to solve; however anyone that owns a AR-15 could benefit from this buffer. The .223/5.56 out of an AR-15 doesn’t really have that much recoil to complain about, but groups can quickly grow out of control the faster one pulls the trigger. Using MGI’s buffer makes follow up shots incredibly more accurate–it prevents the sights from jumping around and makes the AR-15’s muzzle rise the equivalent of an extremely loud airsoft gun.
The MGI Recoil Reducing buffer for the AR-15 has the highest ratio for ease of installation and added benefit than almost any upgrade you outfit an AR-15 with. The average shooter who just bench shoots their AR-15 might not see much benefit to the MGI buffer. On the other hand, competition shooters such as 3 gun participants, or tactical shooters could see some added benefit since their rapid follow up shots would be in noticeably smaller groupings. The price may seem a little steep for a buffer at $140 considering the stock buffer costs a few dollars, but if you’re running out of things to enhance on your AR, or if you’re looking for every advantage and edge you can get, then the MGI Recoil Reducing Buffer would be a go to upgrade.Read More
