    overall performance

    Published by Matt Yager on Aug 10th 2020

    the screws that were supplied were far to long. I thought for sure they would be touching my barrel when screwed in tight so i took a dollar bill and checked to see if the barrel was still free floating. It was but not by much. The bill would get caught on the screws if it was not snug against the barrel. went down to hime depot and purchased shorter screws.

    4 inch rail

    This rail fit exactly as it should. Fit flush to the bottom of my Grayboe stock. I had ordered a Seekins rail at first but it in no way fit the flat foregrip of my stock.
