    I’ve converted all my ARs and PRS rifles to ARCA rails and these are the best. The extra grooves really look your bipod in and let you ratchet it up and down the rail as required.

    Excellent Fit and Finish as we have grown to expect from Arca Rail. Good design fits with a variety of front attachment bolt locations. It does have the Dimpled Sides rather than the smooth sides.

    Perfect fit and finish. I wanted an ARCALOCK rail for my Bergara HMR Pro but didn’t want the length that the longer rails provide. This 4.25″ rail is exactly what was needed.

    This little rail is exactly what my CZ MTR needed. It was a plus to have the T Nuts included with the rail.

    James C. (verified owner) – January 22, 2022

    Super easy to install on my CZ 457, the rifle uses locking nuts for the sling loops so you already have built in holes with metal sleeves and nuts thay fit the bolts provided with the rail.

    Luis B. (verified owner) – February 15, 2022

    Nothing better than the bumpy edge of the A419 arca system paired with their clamp to prevent slippage and also prevent over tightening!!!
    Fast shipping, all the screws and quality products!

    Game changer. One will be going on all my rifles. Being able to quickly attach it to my Vortex Summit Carbon makes it worth the extra weight on my hunting rig. Gives you a quick and extremely stable shooting position from prone to sitting or on a knee.

    The 4.25″ rail is the right length to replace my two swivel studs so I can run a bipod with an arca attachment. Install was very easy on my Grayboe stock – just remove the swivel studs and use the included 10-32 screws to attach the rail.

    Used these on 3 Ruger Predators mounted in Magpul Hunter stocks. Very simple install with M-Loc nuts. Had to counter sink rail so flat head screws would fit flush on rails. Project worked perfect and guns now work with Accu-Tac bipods.
