    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.

  3. Wm Andrew C. (verified owner) –

    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 was the perfect upgrade for my Bergara HMR along with the Harris S Bipod! The install was so easy a Marine could figure it out, and the fit is perfect!

    Perfect for a light weight hunting rig. Locks your rifle solid even in magnum calibers.

  29. Steven Smith (verified owner) –

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

  30. James C. (verified owner) –

    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.

  31. Luis B. (verified owner) –

    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!

  32. Bryson (verified owner) –

  40. Travis J. (verified owner) –

    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.

  47. Steve Billieu (verified owner) –

    Dovetail Rail attaches easily to my Bergara Rifle. Atlas Bipod attaches to Rail very well!

  48. John W. (verified owner) –

    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.

  59. Robert Abernathy (verified owner) –

    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.

    ARCALock is the best ARCA system out there, bar none. Zero movement when tightened down.

  67. Cristian (verified owner) –

    Good

  68. Thomas (verified owner) –

    Nice product. Only suggestion is to counterbore a bit larger to accommodate standard socket head screws.

  69. Larry McCormack (verified owner) –

    Solid rail piece

  70. Adam Bell (verified owner) –

    quality product as always

  71. Brian W. (verified owner) –

    Takes up 2.5 mlok slots or so, which is why I went with it. Have to order mlok hardware seperate. Make sure you order 419 specific mlok hardware.
