• 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

• Available in 12” ($349.95)and 14” ($359.95)

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 mounting system does not sacrifice strength, stability or accuracy over bulkier designs. The oversized 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. rail interface solves multiple installation issues our gunsmiths have encountered with other rail systems in over a decade of building thousands of our custom AR 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. 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 1.69″ accepts low profile gas blocks. 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.
