CTK Picatinny Rail for LUTH-AR Stocks

I, for one, was happy to see the release of the LUTH-AR stock, as it provided a lower-cost, lighter, weight competitor to the Magpul PRS (review coming on the LUTH-AR), but the stock is missing a few features that endears the PRS to me.

CTK Precision our of Clintonville, WI has stepped up with a solution to the largest complaint I have had on the rifle, the lack of a rear monopod mount. The little rail section is added to the bottom of the stock quickly and easily through a single mounting point. Adding to the additional picatinny rail functionality, the rail adapter also includes a sling swivel mount.

The adapter is available directly from CTK for $35.00

    Minor typo in the first sentence of the second paragraph, it should be read “out of” instead of “our of”.

      Also “lighter” and “weight” should not have a comma betwixt them.

  • RocketScientist

    Anyone have a source for a rear monopod that wont break the bank? I don’t need it to be particularly fancy, but I’m amazed at the cost of all the monpods I’ve seen out there. Especially for such a simple device.

  • Porty1119

    Can I mount a rear-facing strobe on that rail to signal my fellow operators when I am about to back up?

    • Ethan

      Infrared, of course. Operators only use infrared strobes with their NODs. ;-P

  • Alex

    I have that upper! Reverse your scope mount so the nuts face the other side. I know it’s rare to have interference between your knuckle and the hardware, but when it happens it’s not fun.

  • ghost

    So you can hang more stuff on it.

  • ghost

    Can I hang my pickabeer cooler rail on it?
