3 of 5 You Get What You Pay For. June 9, 2021
Reviewer: Caleb Nino from Arizona  
My brother and I both bought these less than a year ago. Both of ours have now cracked open (NOT from mishandling/dropping - but from normal usage, loading, shooting, and carrying. I have only a few hundred rounds through mine. These people are pretty hard to get a hold of which makes the "lifetime warranty" not worth much.

Spend the money, buy factory steel mags and save the headache.

5 of 5 pretty good. March 16, 2021
Reviewer: Ethan from Crack Haven Formerly Known as Washington  
I got 2 of these, both of them are really nice. Doesn't stick out a whole lot but shows off about 3-4 round in the mag. It's nice to see Winchester Ranger in a clear, lol. One mag didn't drop too freely but I have that issue with some factory mags too.
