MGI Recoil Reducing Buffer Review

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.

(video is slowed down 98%, watch in 1080p for best detail)

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.

Rainer Arms Urban Carbine (RUC)

Rainer Arms Ar-15

If you’ve shopped around for parts for your AR, particularly higher end parts, chances are you’ve ran across Rainer Arms once or twice.  Rainer Arms has been selling AR-15/10 parts and making AR-15 uppers for quite some time, but now they’re offering a complete rifle.  Their new RUC is basically a high end carbine upgraded with industry leading parts such as a Gun Fighter charging handle, Diamond Head BUIS (Back up Iron Sights), the new Magpul MOE+ grip, a Vltor iMod Carbine stock plus a bunch more as you can see in the video below.  I personally like the Rainer Arms Evolution Free Float System; its light weight and gives the rifle a distinct look.

Rainer Arms is offering two flavors of their new RUC– a 14.5″ barrel model with a pinned muzzle and one with a 16″ barrel. The 16″ RUC weighs 6 lbs 11 oz and the 14.5″ weighs only 6 lbs 8 oz.   Considering the quality construction Rainer Arms is known for (their customers absolutely swear by them) and the premium parts installed on the RUC, it’s price is fairly reasonable at $1300.

Sig Sauer 1911 Fastback Nightmare

Check out Sig’s latest 1911, the Fastback Nightmare.  Sig has been producing a bunch of different 1911s this year from the 1911 TACOPS, the 1911 TACPAC, the Scorpion and now the Fastback Nightmare.  What makes the Fastback Nightmare different is that it features a rounded mainspring housing similar to the Kimber Super Carry.  Other features of the Sig 1911 Fastback Nightmare are low profile night sights and some custom double diamond G10 grips.  No word on price yet but my estimate would be from the $1100-1300 range.

Big thanks to for the specs and pics.

Magpul MOE Scout Mount

MOE Scout Mount PIctures

Another Magpul accessory for their MOE line has been released, this time its the new Magpul MOE Scout Mount.  This new light mounting accessory from Magpul differs slightly from their illumination kit with its cantilever design positioning the light a little bit more forward for a more ergonomic option.

The Magpul MOE Scout Mount is designed specifically for the SureFire Scout Light Weaponlights and other 1913 Picatinny mounted lights–if the Scout Light is out of your budget (around $300) then the Streamlight TLR series (starting at $100) will attach just fine.  It features a low profile design and is made of polymer keeping the weight down.  The MOE Scout Mount is designed to attach to Magpul’s MOE handguards.  Two models are available–one for the left side of your handguards to mount a light at the 11 o’clock and one for the right, 1 o’clock position.  Just like other Magpul products the MOE Scout Mount is priced very reasonably at only $10 and is available now at your local or online gun stores and directly at
