Front Sight Picatinny Rail


Product Description

Finally, something incredibly useful, elegant and extremely functional for your often overlooked bayonet lug.   This Generation 2 Picatinny Rail from Crosstac now features a retooled mount for our big ring (included) that allows you to quickly and easily mount the ring on either side of the rail.

If you're accessorizing your AR and are frustrated with the mounting options out there... your problem is solved. For more details, please watch the video below. This is the only front sight rail to take advantage of the bayonet lug everyone has, but never uses. Perfect for mounting accessories such as lights or lasers. Provides very convenient positioning of your accessories for use with the offhand.

Note: Requires industry standard mil-spec bayonet lug on your front sight.  Non mil-spec bayonet lugs (on rifles such as the Ruger AR556) will not allow mounting.

  1. Fits like a glove

    Posted by James Cook on 25th May 2018

    Item fits great and is attached very tight no movement what ever it is narrow and almost no weight added, I looked at many others of this type and I believe I purchased the very best on the market, would like for a replacement gun sling roll pin to be included in the package..good PR, thanks for your product.

    Very pleased with product on receipt, good machining and finish...having someone available to lend a third hand made install VERY easy.
    Haven't had an opportunity to test fire with the rail mounted, but judging from how solidly it attached, I expect no problems at all.
    Great praise on the turn-around time...placed ordered Mon, received on Thurs.

  4. Nice Product!

    This Front Sight Picattinny Rail gives my bayonette lug purpose on my AR once again. This is an innovative product that allows for a perfect spot to mount a laser pointer, tactical illumination or a vertical grip. In addition, the sling mount is a perfect location for the forward attaching point of my 2 point sling.

  7. Rock Solid

    Posted by Ron H. on 26th May 2016

    I put this off a while, but finally removed the stock sling to put a rail on the bayonet lug. I'm using this for a green dot laser. The mount fastens in 2 places making this mount rock solid. The product is well made and my laser comes off and goes back on without additional adjustments to the 100 yd setting I have. This was a good addition.

    After searching for a few hours to see if a mount like this was available I uncovered a half a dozen products for sale. I went with the Crosstac because of its superior design and the length of the bottom rail allowed my lazer and a additional sling mount I already had to fit one behind the other. Arrived in two days, great customer service. great people to do business with. :-)
