Got Rail? by Legacy Reviewer, November 28, 2013
If you need a way to add a bit of rail to your barrel and don't want to tap it or make other permanent modifications, this will fit the bill. Pros: No permanent modification required Cons: None

Tommy from Ga. by TommyG, October 16, 2020
Wanted a small rail to mount a light on the barrel of AR15 M4. Strong lightweight and quality item. Fit my needs and price was good. Came with Allen wrench for mounting. Fit and finish of mount is excellent.

Buyers beware by mike, Verified Owner, February 25, 2022
Rail is out of spec. Tried fitting a Surefire Scout light to the rail and failed. Attachments that don't require in-spec rail to fit may be fitted. Maybe worth half the listed price. Glad it worked for some people.
