It technically worked, but the thread alignment was a little off from the bore.
Used this as part of a kit to thread a barrel. I'm not sure if it's possible to get a perfect alignment with the bore without using a lathe. The threads will still work fine for most muzzle devices, but not good enough for a can. I think reducing the O.D. with the piloted annular cutter is mostly responsible for the misalignment, at least more so than the die starter and die cutter.

As Advertised
Arrived on time and threaded right in to my die. The pilot diameter measured +/- .001” of 0.298”.

Worked as advertised
A little mix-up at first....I only received the 0.210 . However, after contacting the seller they sent two more that were as advertised.

Absolutely Perfect
Absolutely perfect. I have had a horrific time trying to find one that actually fits. Luckily with this one they send two. The smaller one fit perfectly.

This is perfect for threading Soviet 5
This is perfect for threading Soviet 5.45x39 barrels that have 1/2 inch outside diameter. The shank on this tool mics out at exactly 5.45mm which fits inside the bore perfectly without any play. Other TAT's for 223/5.56 are .010 larger in diameter. I bought this TAT in 22LR hoping that it would fit my 5.45mm bore. Not disappointed and very happy!
