1 1/4″ Crow Foot Barrel Nut Wrench (1/2″ Drive) For Parallax Tactical AR15 Handguard

(131 customer reviews)


823 in stock


Spare 1 1/4″ Barrel Nut Wrench for use with the Parallax Tactical AR15 Barrel Nut. These have to be ordered separate from the parallax tactical rails, they are not included. We had these special made just for our customers here at B. King’s Firearms. Most of the Crow Foot Wrenches in the market today do not work on the parallax rail barrel nuts because they are to wide. We have been using the Stanley Pronto which is a $30 piece…That is just not reasonable for the occasional builder who may only purchase one of these rails. This Crow foot will also work on a lot of other brands barrel nuts.

  • Made in the USA From 1018 Solid Steel.
  • Black Nitrided at H&M
  • 1 1/4″ Crow Foot
  • 3/8″ Thick
  • 1/2″ Drive
  • 6.5oz

  1. Barry (verified owner)

    Little loose on barrel nut but worked

  2. Tshering T. (verified owner)

    Great little tool, works as described. It really worth more than the price. I paid only $2.77 for USPS shipping and it showed up in my mail within three days from Washing to Texas. It was a nice buy.

  3. Evan (verified owner)

    Quick ship! AAA+++

  4. Tony Walker (verified owner)

    Just what I needed!!

  5. Larry O. (verified owner)

    A perfect tool for the job. I couldn’t get my Parallax Tactical barrel nut timed right because my other crowfoot wrenches were too wide. Using this wrench allowed me to time the barrel nut perfectly and now my handguard is aligned perfectly. Thanks to B.King’s for this simple but effective tool.

  6. Pete (verified owner)

    Very happy with everything I buy from B. King’s…great products and fast service.

    Price was right and it did the job installing my AR hand guard tube. It should be included with every hand guard since it is needed for install of the barrel nut.

    The barrel nut wrench worked perfect. It also has a very cool finish, just like it came off the milling machine. Thanks, Robert.

  31. Eric Chavez (verified owner)

    Perfect fit. Some surface corrosion/rust, but nothing that affected function. Only complaint was the package got redirected from final delovery point (Jacksonville, FL; where I live) to somewhere else. Not a B.King problem though.

  51. Jason M. (verified owner)

  52. adam (verified owner)

    It’s nice that BKING recognized a problem with certain wrenches and barrel nut connections, and designed a slimmer tool. Worked great and seems high quality at a cheap price.

  77. DONALD H. (verified owner)

    Worked well on parallax handguard , it would be a better if it fit a little snugger one barrel nut Or maybe make out of tool steel or hardened it. But it did the job

  78. Dennis H. (verified owner)

    This is a great little tool at a great price wish I had know about B. King’s sooner,ordered a extra one just to have in case lost one. I will most definitely be ordering again. D. Harrson USN Ret.

    surprising something required is not included….it is solid/heavy well

  91. nramoore (verified owner)

    Got this today and it worked like a champ on the barrel nut I was needing to torque. Thanks BKF…

  92. John C. (verified owner)

    Very happy with this order. They shipped within a day, which is something that most large retailers seem to have a problem with in 2020. The wrench is exactly what I needed, fits perfectly and is made out of a good quality steel. The level of fit and finish is right where it needs to be; It’s not “pretty” and it doesn’t need to be, and if it was they would be charging 3 times as much. Great job guys. I’ll definitely be buying again in the future and I would definitely recommend them to anyone who asks.

  93. Anonymous (verified owner)

    I haven’t received it to properly review but I know that because of COVID19 they are backed up.

  94. Randy (verified owner)

    Arrived with a fair amount of rust on it… no problem with function, but…?? Baggie next time? Very tight fit. Maybe 1.23″ instead of 1.25″ Right price anyway.

  95. Claude S. (verified owner)

    Product as advertised, very quick delivery. Very Happy with purchase.

  96. Samson F. (verified owner)

    Fits well with the wrench and has no problem tightening the barrel nut from Franklin Armory.

  108. Ron P. (verified owner)

    It’s a wrench

  109. Dale J. (verified owner)

    Works great, fit great. The only improvement I would make is to give it some paint/plating to protect it from rust. After I was through using mine I primed and painted it black. It is bare 1018 steel so it will rust pretty quickly if left exposed.

  110. Anonymous (verified owner)

    Worked great

  111. Matt L. (verified owner)

    Worked slicker than a booger on a door knob

  112. Robert L (verified owner)
