Impressive product by brain, Verified Owner, April 13, 2023
Fit beautifully on my Sig 516. Nicely lightweight and rigid. Extends hand-guard for better purchase and allows for more room for accessories. Looks great too. Surprised by how robust the carbon fiber seems.

As many have stated for fit and functionality, this is 5 stars. Not to mention the options for an aftermarket handrail is extremely limited. The biggest short fall is that to clean the piston you have to take the hand guard off. This doesn’t require ...

A lightweight upgrade that gets rid of the cheese-grater rails by TB, February 22, 2019
As the AR platform continues to develop, many of us are getting used to MLOK or Keymod rail systems that don’t require you to run rail covers or have the bulk associated with 1913 rails on all four sides PLUS rail covers. Lancer did a solid job deve...
