Most Helpful Positive Review Wheeler Receiver Lapping Tool AR LR/10
I ALREADY OWN THE WHEELER AR/15 LAPPING TOOL. I AM NOW BUILDING SEVERAL AR/10's. BECAUSE THESE COMPANIES ARE TURNING OUT UPPERS LIKE POPCORN, SOME OF THE UPPER RECEIVER BARREL SURFACES ARE AS MUCH AS 0.005+ (THOUSANDTHS) CANTED EITHER LEFT, RIGHT, UP OR DOWN. THIS CAN CAUSE ERRATIC BULLET IMPACT AS ...

Most Helpful Negative Review Poor quality and improper handling.
Tool arrived with scuffs, dings, and the receiver shaft has a small ridge that runs its length, tool/not round. Even after removing the burs cleaning up the dings and lubricating liberally, the out of round shaft scared the interior of my upper where the bolt resides. The tool was properly packaged...

Was not true

by Jim, Verified Owner from MO, United States Written on December 26, 2024
Threw mine in the lathe to square off the giant chamfer on the working face of this tool that really shouldn't be there and it wasn't even true. Very disappointing. I should have just made my own.
Pros:
  • None
Cons:
  • Better off making it out of a stick in the woods with nothing but a rock
Best Used for:
  • Paperweight
Would recommend: No

doesnt fit

by Seth, Verified Owner from TX, United States Written on December 1, 2024
Don’t waste your time with this… they didn’t increase the size of the cutting head to accommodate AR10 barrel extensions so it will not cut the entire surface… Idk how anyone at Wheeler could have approved this but they need to find new people
Pros:
  • NONE !
Cons:
  • doesnt work
Would recommend: No

Highly effective

by Sgt.Brad, Verified Owner from OH, United States Written on October 15, 2024
In just a short period of time, this tool let's you alleviate one possible inconsistency. Shots were more consistent after truing the face of the receiver.

laps great BUT!

by drcmcico, Verified Owner from OH, United States Written on September 18, 2024
Says it’d work for an AR-10 but the diameter isnt round enough for an Aero Precision upper. It leaves about a 1/16th” metal ring that it didn’t lap off.
Pros:
  • worked great for 25 months
Cons:
  • None
Would recommend: No

Not built right - avoid

by Jim, Verified Owner from OR, United States Written on July 31, 2024
The concept of the lapping tool sounds good. I do see how the mating face of my AR10 upper could affect accuracy which lapping would "True" the alignment to the BCG and barrel extension, which seems like it couldnt hurt to squeeze out a little more accuracy. However this Lapping tool is poorly built and executed. The lapping face of the tool is too narrow and doesnt go to the outer edge of the upper mating face. It is also poorly machined and has a "grooved" face which put round/circular depressions in the mating face of my upper. If I hadnt caught it soon enought it could have ruined my upper all together. I would avoid or buy a better quality lapping tool from an other manufacturer.
Pros:
  • None
Cons:
  • everything
Best Used for:
  • Not buying
Would recommend: No

almost ruined my upper

by ejams, Verified Owner from IN, United States Written on July 14, 2024
The lapping face of the tool is too small and has a chamfer on the edge. That chamfer began to grind a conical gouge into my receiver and almost ruined it before I caught it.
Pros:
  • Black and thick.
Cons:
  • Heavy
Best Used for:
  • Clubbing small animals
  • if you're brave enough
Would recommend: No

Well Made Product

by Jon, from OK, United States Written on July 29, 2020
Excellent tool and very easy to use. Lapping can be done without using the drill adapter. You only need to remove a few millimeters to square the barrel mating surface. The only issue is the package had been opened and everything was rattling around in the box. Doesn’t appear to be damaged. -2 stars for selling an open package.
Pros:
  • None
Cons:
  • Open package
Would recommend: Yes

Worth the money

by DPS, Verified Owner from TX, United States Written on June 26, 2020
Just a bit of oil on the main journal and then the cutting compound on the larger one (just follow the instructions) and in a few seconds of use, you are good to go.

Very easy to use and a good value for the money. I'd expect getting dozens, if not many multiples of that, uses out of the amount of compound they send you alone. If properly stored, I can see the tool itself lasting forever.
Pros:
  • Value an quality
Cons:
  • None
Would recommend: Yes

Wheeler 308 Lapping Tool

by Joe, Verified Owner from CA, United States Written on May 4, 2018
I bought this to use on a AR 308 build to make sure the surfaces were straight and true. It was easy to use and did its job without an issue. The flexible attachment for a hand drill was useful as well. You could make the same tool using a lathe but for those who don't, the price of this tool is just right.
Pros:
  • easy to use
Cons:
  • None
Would recommend: Yes
