Most Helpful Positive Review MI URR is for pimps
This is the only correct receiver rod to loosen barrel nuts. You can split (as I have done) your receiver at the indexing pin slot or barrel nut if using a Geissele or Magpul BEV block. Works just as great for torquing as well. Highly recommended.
Most Helpful Negative Review Sail was clocked waaay off
The sail was visibly hanging to one side. Its so tight in the barrel extension and upper, it won't fit unless the two line up just-so, yet the tool is mistimed. What a joke. Apparently this isn't a long enough review for the wibsite, so I'll add it took me weeks to connect with MI for replacement. I...

Great product

by Erik, Verified Owner from OR, United States Written on February 20, 2026
This tool worked perfectly to install my AR 15 barrels without worry about twisting the upper receiver. What worth the money if you’ve got one or more barrels to install.
Pros:
  • Fit and Finish
  • Built qualities

100% Satisfied

by Mark Markiewicz, Verified Owner from MI, United States Written on January 11, 2026
I purchased the nickel version during a flash deal for the lowest price throughout the year.
I used it on an Aero Precision M4E1 threaded and Faxon 6" SS BO barrel.
The barrel to upper receiver is a slight thermal fit.
It takes heating the upper with a blow-dryer for the barrel to seat.
Not sure if the barrel extension is on the high side, or the lower bore is on the low size.
Either way the fit of the tool, is very good.
No slop but not a force fit. It lined up the pin and ramps perfectly.
I am 100% happy and satisfied with the price, shipping and the tool Optics Planet sent me.

Nice product

by Mike D, Verified Owner from FL, United States Written on January 10, 2026
I already have the BEV Block, which is also a nice product. However, I wanted something a little more industrial to add to my AR toolbox. This tool gives you the option to take off the upper piece (3x screws, wrench comes with it), if need be. This tool is rated very well, and is well built. It does cost a little more than some others, however you won't be disappointed.
Pros:
  • Well built , Great Design,Easy to use
  • Well built, easy to use
Cons:
  • None
Best Used for:
  • ar15 platform

modification

by 1st time, Verified Owner from UT, United States Written on January 5, 2026
Received product it is well built, but I had to have the keyway machined down a few thousandth due to the build of my upper receiver.

Midwest AR10 reaction rod

by Tom, Verified Owner from VA, United States Written on January 3, 2026
This is the best AR10 reaction rod available. Solid, versatile and the best thing is that the lugs are cut in such a fashion as to not scar the barrel extension. I wish I would have got one earlier.
Pros:
  • Great machine work and fit
Cons:
  • a bit pricy
Best Used for:
  • AR10 receiver and barrel handling
Would recommend: Yes
