Great price for this adapter
Wasn't sure what to expect, but it seems to be machined correctly and it fit perfect.

Threads True, Fit Perfect — Held Up Under Pressure
Picked this up to adapt 1/2x28 to 5/8x24, and it did exactly what it was supposed to. Threads were clean, concentric, and snug—no wobble, no hassle. The included washer was a nice touch and made installation smooth. I tested alignment with a precision ground rod, and it was spot on. Even under high-pressure situations, the threads held up beautifully with no signs of stress or misalignment. If you're looking to run different muzzle devices or just need a solid adapter that actually lines up right, this one does the job perfectly. Great price, rugged, and no surprises—just the way it should be. It's a lot cheaper than the other options out there, not sure if I got a perfect one that was made on Wednesday, but mine works great. For the price, it's worth a shot.

Works as it's supposed to
After spending too much $ at some other 'specialty stores,' and having those not work due to threading issues, I bought this & it works great.
