SureFire Buffer for HS Model 5.66mm Review

First Impressions of SureFire Buffer for HS Model 5.66mm

The SureFire Buffer for HS Model 5.66mm isn’t exactly the sexiest piece of gear, but its impact on rifle performance can be significant. Manufactured by SureFire, a name synonymous with quality and reliability in the firearms industry, this buffer promises to solve cycling issues in short-piston AR-15s and enhance reliability when using suppressors. I was intrigued to see if it lived up to the hype and could tame some of my notoriously picky rifles.

My interest in this buffer stemmed from a persistent issue with my 11.5″ AR pistol. It has a fixed-gas, short-stroke piston system. I was experiencing inconsistent cycling, especially when suppressed, leading to frustrating malfunctions during range sessions. I hoped that the SureFire Buffer’s additional mass would smooth out the action and make my pistol more reliable.

Upon unboxing, the SureFire Buffer felt solid and well-made. The matte finish is clean and professional, and the weight is immediately noticeable compared to a standard carbine buffer. The build quality instilled confidence. I’ve used cheaper buffers in the past that felt like they might fall apart after a few hundred rounds.

I considered several alternatives, including heavier H2 and H3 buffers from other manufacturers. I ultimately chose the SureFire Buffer because of SureFire’s reputation for quality control and the specific design aimed at addressing issues with short-piston systems. I was betting on engineering expertise over saving a few bucks.

My first impression was positive; this buffer felt like a premium product. I was cautiously optimistic that it would solve my cycling issues and improve the overall performance of my AR pistol. I was eager to get it installed and put it through its paces.

Real-World Testing: Putting SureFire Buffer for HS Model 5.66mm to the Test

First Use Experience

My initial testing ground for the SureFire Buffer was my local outdoor shooting range. The day was moderately warm with a slight breeze, creating ideal testing conditions. I primarily focused on firing my 11.5″ AR pistol, both suppressed and unsuppressed, using a variety of ammunition types, ranging from standard 55-grain FMJ to heavier 77-grain OTM rounds.

The SureFire Buffer made an immediate difference in the cycling smoothness of my AR pistol. The felt recoil was noticeably reduced, and the action felt less “choppy.” I experienced no malfunctions with either the suppressed or unsuppressed configurations.

Installation was straightforward, taking only a few minutes. I did not have to make other modifications, such as changing springs, to gain optimal results. There were no immediate issues. The performance improvements were clear and noticeable right away.

The finish has held up well, with only minor cosmetic scratches from regular use. Internally, the buffer still functions as smoothly as it did on day one. Cleaning and maintenance are simple; a quick wipe down with a clean cloth is usually all it takes.

Compared to my previous experiences with standard carbine buffers, the SureFire Buffer is a significant upgrade. It provides smoother cycling, reduced recoil, and increased reliability, especially when firing suppressed. It has completely resolved the cycling issues I was experiencing with my short-piston AR pistol.
