Mcsr v12 handguard - Seekins Precision MCSR KeyMod Rail System

This handguard is very well built and light wieght, I have the keymod versions. The diameter is large enough to fit over barrel suppressors and krink breaks. It looks good on the rifle too. When installing the barrel nut in order to get enough torque and maintain gas tube alignment and handguns screw hole placement, I used a long pin punch through the barrel nut and into the upper receiver, this worked very well. The installation instructions were lacking in details such as this, and Seekins cx service, although super friendly, was not very helpful with installation tips such as this.
