NEW! The Kel-Tec RFB Handguard

(5 customer reviews)


Kel-Tec RFB Handguard

SKU: 1020 Category:


After many requests, it’s finally ready.  The Kel-Tec RFB handguard.


Note, this is the .308 / 7.62×51 NATO version of the Kel-Tec bullpup.  The ejection system is forward out the front of the top of the gas system, hence the ramped front portion of the rail to ensure smooth ejection.  An optional top cover comes with this rail just forward of this so you can utilize BUIS or other items forward of the gas block and eliminate the plastic clunky factory rail and aftermarket quad rail.


Machined in 6061-T6 aluminum and powder coated BLACK for a grippy, durable finish, these are all that was needed to make a great rifle even better!  Other colors will be added next month.


You will receive:


  1.  Handguard
  2. Top cover forward of gas block, your choice whether to mount it or not, purely optional
  3. Front stay pieces (3) that go around the bottom legs of your gas block
  4. Front standoff
  5. Rear stay pieces (2) that screw into the rail and go around the rear take-down pin cups
  6. Rear standoff
  7. All required screws

We do not include instructions because it’s a very simple install, probably 10 minutes at best and we detail them here.  Please return to this page for installation once you receive your rail.




  1.  Remove Factory Handguard

2.  Open box, check for all of the above components, some of which are pre-installed on the rail

3.  Remove front stay assembly from baggy, it will slide onto the gas block as shown.  Remove the standoff and set aside.  Loosen the screws and slide onto the bottom of your gas block.  Once in place, snug screws just slightly so it will hold position and insert the long silver standoff through the hole.

Note, this is a cast part from Kel-Tec and some fitment and alignment is required, light tapping with a RUBBER or PLASTIC mallet may be required to center the standoff.  Once you get to where you slide your rail on, check the alignment on the screw holes on the front stay.  You may need to tap the assembly forward or backward and re-tighten all screws so leave them a bit loose the first time you install the front stay.

4.  Once everything lines up well, remove handguard one last time and tighten all screws in the front stay assembly to lock alignment – USE BLUE LOCTITE (not provided).

5.  Insert rear silver standoff through the rear takedown pin hole and center.

6.  Slide the rail over the rifle front to rear.  The rear cups/stays will slide over the takedown pin cup.

7.  Insert BOTTOM TWO screws into the front stay FIRST.  These pull the rail up into alignment with the rest of the screw holes.

8.  Tighten rear screws, use blue loctite.

9.  Insert remaining front screws, using blue loctite on all screws ONE AT A TIME to not lose the alignment (not included), then tighten down all screws 16-18 inch pounds.

10.  All screws torque down to only 16-18 INCH pounds of force.  DO NOT OVER-TIGHTEN.  It’s not necessary and you’ll strip the torx heads.  Let the loctite do its job.

11.  Install optional top cover, screw locations should be self-explanatory.

If any of the above is questionable AT ALL to you, please email us BEFORE you force something or take it to a gunsmith who will have it together in about 10 minutes.  DO NOT FORCE IT OR BEND IT.  We have NO obligation to warranty items damaged during installation.


Enjoy, and thank you very much for your business!

    Looks awesome! Seriously, makes my 18.5 look like it’s from space and was built to defend against acid bleeding aliens. Also provides great accessory attachments letting me mount an afg further forward to improve ergos without lengthening the rifle. Floats around the barrel so a forward bipod won’t effect poi unlike the quadrail and the top shroud enables shooters to go ‘thumb over bore’. Have I mentioned it’s light? as in I haven’t noticed a difference from having the grip rail on before. I’m having way more fun with my rfb. If you are still reading the answer is ‘Yeah, you should get one.’

    The stock plastic handguard on this gun just looks awful, so much happier with this style of handguard on my rfb now. Plus it goes out further than the stock handguard which is great if you want front flip up sights, a bipod, flash light etc. instalation is easy enough. Once its on the gun is even more solid than before. One happy customer here.

    An excellent replacement to the plastic stock handguard and very easy to install. Kel-tec’s lower picatinny rail is also compatible with it. My only gripe is that stripping and reassembly requires a screwdriver set (I personally recommend a set from Oria via Amazon). That said I’m very satisfied with my purchase and it makes my rifle an even bigger conversation piece than it already is.

    This is an absolute beast it’s so much better than the stock set up you won’t regret getting it. Just use some patience installing it and you’ll be rewarded with essentially an entirely different weapon than you started with. Top notch craftsmanship
