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. It is machined from 6005A-T5 Aluminum Extrusion and has a Mil-Spec Hard Anodized Black Finish. It has quick custom positioning of supplied rail segment. The 1.47" internal diameter is compatible with most low profile gas blocks. 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 that gunsmiths have encountered with other rail systems in over 10 years of building thousands of Wilson 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. Integral push-button Q.D. sling swivel attachment points are located on both sides of the T.R.I.M. for the ultimate in sling mounting versatility.
