Do you need a rock solid mount for your Long Action Christensen Arms Ridgeline? Are you tired of your scope rings slipping or denting cheap aluminum Picatinny rails on your Mesa?

If so, our premium stainless steel or titanium scope bases are nearly indestructible. They will securely hold your expensive optics, and prevent point of impact shifts from ruining your shot.

Our bases are proudly made here in America on our state of the art CNC equipment. You have a choice between 17-4 Stainless Steel, or the ultimate: Grade 5 Titanium.

Our bases are strictly held to tighter tolerances than allowed under the Picatinny standard (MIL-STD-1913), ensuring complete compatibility with all Picatinny style, as well as Weaver style scope rings.

They are available in a natural, satin silver finish (bead blasted), or with an incredibly tough black finish called Cerakote.

    Picatinny precision titanium rail

    Posted by Noel Goyhenetche on 17th Apr 2024

    I’ve purchased 3 of these rails for my rifles. They fit tightly and after firing many rounds through the first 2 rifles and being happy with the set-up using these rails I bought a third. Great quality and the service is excellent. Mr. Murphy stands behind his products and is quick to respond to any questions or issues you may encounter. I’m very pleased with the product and service I’ve received. Thank you!

    Perfectly crafted piece. I will not buy bases from anyone else. Cameron is by far the best I’ve ever dealt with. Customer service is outstanding

    Christenesen Ridgeline LA 20 MOA

    Posted by Matt Winn on 23rd Nov 2022

    This is the 4th Murphy Precision Titanium base that I've personally ordered from Murphy Precision and I am very pleased as always with the quality of craftsmanship and the accuracy it helps provide my rifles. I have placed numerous long range kill shots on animals in Alaska since 2015, most of them beyond 500 yards with ease accompanied with tactical scopes. I have referred numerous friends and family to buy this product and never had any complaints from them either. I cannot recommend a better product!

    Great rail mount for my Burris eliminator 3 on my Christianson arms ridge line titanium 300 win mag. Couldn’t have asked for better, followed Cameron’s instructions & now I have a killing machine, the combo delivers accurate & consistent shots as far as you are capable. One shot one kill on my 1st pronghorn hunt thanks Cameron.
