Save Your Money

Being an AZ guy I wanted to like this rail. Sadly, spent another $40-60 and get quality. It requires a crow foot wrench that you need to order from Guntec at an additional $20 plus shipping. If you somehow mount the barrel nut without their tool the aluminum barrel nut will be marred up. It is virtually impossible to install so that the receiver and hand guard top rail align. The UTG has a better system if you watch their video. I will leave this Guntec junk on until I can get another Troy rail that I should have bought in the first place. Primary Arms is still the best in the business.
