Kel-Tec RDB Rhino Rail – NEW!

(6 customer reviews)


SKU: 1010 Category:


This is the long-awaited 2nd version of the 6061-T6 aluminum handguard for the Kel-Tec RDB.

After many requests, we have created a 2nd version we call the “Rhino Rail”.  Squared off at the front instead of angled, this is the same overall length as the original Raptor rail, but due to being squared off at the front adds one M-Lok section on the left, right, and top sides for accessory mounting or better hand gripping.

Powder coated black, this will also be offered in tan and green once we get them back from Cerakote.

For those who have purchased a Raptor Rail, we will be offering an exchange on your rails as well, price depending on condition.

These mount the exact same way with the exact same hardware as the original Raptor rail, so it will be a slip-on replacement.

Yes, we ship to Canada, but no other international shipping due to ITAR.

Thanks again for all your business, we greatly appreciate it!

Installation instructions will NOT be in the box.  We pre-assemble these with the exception of ONE pin that has to be assembled.

Step 1:  CHECK YOUR PACKAGING.  There is a small baggie with your front stay, internally-threaded standoff, and screws for the front mount.  It’ll be in the plastic of the rail but might fall into packaging material.  DO NOT THROW THIS AWAY!

Step 2.  Remove your factory handguard.

Step 3.  The front U-shaped stay goes around your factory gas block and the .250″ holes line up.  We insert the screws into the u-shaped front stay and silver aluminum standoff to mark where they go as they are differently sized.  Remove these screws while noting their position and set aside.

Step 4.  The front U-shaped stay hole is DELIBERATELY oversized .002″.  DO NOT SAND THE STANDOFF OR REAM THIS HOLE.  This creates an interference fit like an AR roll pin to eliminated the wobble the factory plastic handguard has and gives you a tight fit on your rifle.  Simply oil the silver standoff and the holes on the U-shaped stay, line up the front stay and the gas block holes, and hammer the silver standoff into the holes until equally inserted left and right.

Note:  The silver standoff will NOT be flush with the front stay edges.  This is why they call it a “standoff”.  The screws are long enough to allow the rail to be drawn tight towards the stay.

Note 2:  Use a FLAT brass punch to hammer the standoff in.  It will be tight, but it will go.  Take your time.  About 5-7 minutes with slow, deliberate, firm hammer strikes on the brass punch.  DO NOT used a round nose punch, you will mar the threads and the screws won’t insert.

Step 5.  Slide rail onto the rifle starting at the REAR of the rail from in FRONT of the flash hider all the way down until the rear stays’ U-shaped cups are around the mounting points of the rifle receiver.  Insert front screws and snug all screws.

Note 3:  We highly recommend removing one screw at a time once all are tight, applying blue loctite, then re-tightening.  About 8-10 INCH pounds, not a lot or you’ll strip the screw heads.  It just needs to be *snug* if you’re using blue loctite.

Please email us with ANY questions or take to a licensed gunsmith if you are uncertain at all.  Thank you!

    Keep up the great work. Took this out three times so far and shot a good amount. Fit and finish is excellent. Holding up as expected.

    Great product! Excellent addition to my Rdb, very easy to install , can’t wait to add some rails to it

    This is a really good rail for the RDB. I tried to mount this to a RDB-C but I had to cut out a small piece that interferes with the lower receiver. I’d love to see a V2 that has this cut already in the rail so that RDB-C and RDB-S can mount this out of the box.

      Thank you for the feedback. That is a caveat when we sell these for the -S and -C models. The receiver is thicker than the standard RDB. That said we are working at getting a -S so we can do that work ahead of time. Thanks again for your purchase.

    Honestly not much else can be said except amazing quality, fast-reliable shipping. Defiantly a tight fit for install but solid as a rock after. Super happy that you guys provide shipping to Canada!

    Stabilizes the forend and looks awesome. Best mod I’ve seen, truly improves the rifle.

    Fantastic quality! Much easier to install than I have heard in the past, yet it is still absolutely rock solid. Arrived today, got it assembled within a few minutes and went out to the range to test it out, put 100rd through it and it held up about as flawlessly as could be expected.
