Troy MRF Rail Review PART 1: Overview

The Troy MRF Rail System:

Troy has always been a company I know that I can turn to for a quality product.  Yes, there are other great companies out there, but I feel Troy is among the better ones in regards to the build quality present in every product they make.  Their rear BUIS (Back-Up Iron Sight) is known throughout the world as one of the toughest folding sights in existence next to KAC and a few others.  So here are some thoughts on one of the rail systems they have to offer.  Troy touts the MRF as being the “Strongest user-installed free-floating rail system in the world”.  Part of the reason I think they may be right is that fact that their patented clamp mounting system reinforces the barrel nut and also provides the anti-rotation lugs we were talking about earlier. Available in both Black and Flat Dark Earth (and DIY spray-paintable in any color you want) the Troy MRF is MIL-SPEC Hardcoat Anodized and basically gives you the strength and appearance of a monolithic rail.  The rail also features 4 Quick-Detatch push-button sling swivel points.  https://troyind.com/rail-systems-accessories/rails

A quick overview of this project:

For a recent project, I wanted to select a free-float rail I thought would be relevant to the widest audience, as this site targets everyone from LE and military, to competition shooters, to weekend hobby shooters.  First, not all of us have the tools, the knowledge, or the desire to be a gunsmith, so I decided that the easy of installation of a two piece rail would achieve the accessibility problem of rails that need gunsmith installation; for example, some competitors can not spare their AR for more than a few days as this would conflict with competition and training schedule.

Many of the two peice rails on the market require very little to no modification of the host weapon system, and yet offer nearly the same amount of strength of one piece designs.  These “Drop In” rail systems at most require removal of the Delta Ring and Front Sling Loop, and sometimes even allow installation over the Delta ring.  Some will argue that the two piece design is not as strong as a one piece, but I would note that neither design is as strong as a true monolithic AR upper/rail combo.  There are pros and cons of each particular rail system out there, but the requirements of this project stated the need for a drop in rail system that would at least not require the removal of the barrel nut, and at most would require a few touches of a dremel. Now for something really important: There are some two piece rails, and even one piece rails on the market, that rely on the torque of the barrel nut to keep them from twisting.  Most, “drop in” rails mount to the barrel nut, but some of them do not have “anti-rotation tabs” on the edges of the rail where it connects up against the upper receiver.  Now, while I have never personally twisted a barrel nut off with my bare hands, there is fear of front grips giving one enough torque to, maybe during a fall, twist the rail hard enough for it to losen the barrel nut.   There are even stories of this online.  The good thing is that even if your barrel nut turns a little, your rifle will most likely continue to operate.  The bad  part is that the thing stopping the rail and barrel nut from turning 360 degrees and fully loosening is the gas tube, which some forum users have noted may shear from this force; rendering the rifle inoperable.  So “anti-rotation tabs” are a premium feature and usually signify that the rail is a quality accessory and a well thought out design.  So, after some research, I decided one of the the rails that met the above requirements, and would make for a good review.
