Ask a Question
  • What torque specs do you recommend for the screws when installing the rail?

    we recommend just a snug fit, don't have torque specs for the rail.

  • If I use want to install the GB pic rail onto a Renegade stock, do I need to have the anchor nuts inletted into the forearm or will it work simply to use the included machine screws in place of the swivel studs?

    You will use the supplied screws to screw into the existing holes when you take the front studs out.

  • Any idea when these will be back in stock?

    we are probably a few weeks out from having them back in stock.

  • I may not be thinking clearly, but how do you screw this into the stock, while maintaining the sling swivel stud? There are 3 holes on the rail, but only 2 on the stock, and screwing the sling swivel stud in enough to secure the rail makes it unusable as a sling swivel.

    on a stock with 2 front studs, you unscrew the 2 front studs and use the new screws we provide with this rail and bolt the rail into the existing threaded holes.  The large circular hole in the back of the rail is used for quick detach sling loop.

Good looking rail

Rail well-machined and anodized, dimensions accurate. The inclusion of T-nuts is nice. I didn't happen to need them, as I installed on existing stud holes in a Trekker; fitment was excellent. If taking suggestions, I'd like to see Grayboe not package all the pieces/parts in one bag, shaking around, but that's nitpicky with hardcoat that's probably harder than the oxide steel machine screws. Grayboe, if still accepting ideas, might consider a rotation-limited front sling point, instead of the common unlimited...or sell both. On a precision rifle, even in sling supported positions, more than 45/-45 degree rotation just isn't needed, and full 360 can be a liability/PITA if using the sling as a carry strap.

Great solution for oddly spec'd AR handguards

I have an older AR free-float handguard that has screw holes 1.75" apart. Standard pic rails wouldn't fit. I found this on Grayboe and it worked like a charm. Installation took 5 minutes and the fit is rock solid. I mounted a Harris Bipod to it with no issue. Fast shipping too, I highly recommend.

Great solution

I used this to adapt a Mossberg MVP LC rifle to accept a pic rail bipod. The Mossberg had a sling swivel attachment and some oddly spaced threaded holes on the stock. None of the rails I found fit the spacing of the holes. This was the solution! The only thing I would like to see is to add a variety of different screw lengths and threads to make it more universal. I had to some random screws I had laying around from other rails.
