The T.R.I.M. (Tactical Rail Interface, Modular) AR rail has been designed by the Wilson Combat engineering team to be among the lightest, strongest and most versatile compact free-floating rail systems on the market.

Light, Strong and Compact Free-Floating Rail Design
Machined from 6005A-T5 Aluminum Extrusion
Mil-Spec Hard Anodized Black Finish*
Simple, 5-Minute Installation with Common Hand Tools
Easily Removed or Replaced in the Field
Quick Custom Positioning of Supplied Rail Segment
1.47" Internal Diameter is Compatible with most Low Profile Gas Blocks
Please Note - TRIM Rail's ship with anodize finish. Photos are shown with optional armor-tuff finish. If you would like the rail finished in our armor-tuff coating before shipment please add this to your cart as well:

Machined of high-strength 6005A-T5 aircraft aluminum with a Mil-Spec hard anodized finish, the T.R.I.M. rail handguard / interface and its robust, anti-rotational mounting system doesn't sacrifice strength, stability or accuracy over bulkier designs. The oversize and tough nitrocarburized 4130 steel barrel attachment nut reduces heat transfer and the ergonomic handguard design offers a sleek, non-abrasive platform for comfortable dynamic shooting.

Light, strong and easy to install-the Wilson Combat T.R.I.M. AR-15 rail interface solves multiple installation issues our gunsmiths have encountered with other rail systems in over 10 years of building thousands of our custom AR-15 rifles. The entire T.R.I.M. interface can be easily end-user installed in five minutes with common hand tools and can be quickly removed or replaced with a different length rail interface in the field with nothing more than a hex key.

The T.R.I.M.'s attachment points enable the end-user to quickly position the supplied modular Picatinny rail panel on the attached interface in pre-specified locations. A generous inside diameter of 1.47" accepts low profile gas blocks and many of the available piston gas systems.

Note: screw thread pitch is 1/4"x20

These are really nice (I grabbed two of them). The 10.4 was like a matte grey finish, but my 12.6 has almost like a dark purple/burgundy tint (barely noticeable in the light). I kinda dig it, though.

Edit: You can see it in the pic if you look closely. The write-up says that it's pictured with armor tuff or whatever, but that's the one that shipped to me without paying extra.
