5 of 5 Good Quality February 25, 2020
Reviewer: Kyle R. from Baton Rouge, LA  
Got the item very quickly and it was very well wrapped.  Not one scuff or scratch, item was well built too.  Got 1.5" groups with cheap russian plinking ammo so that's impressive.  Will try some good Hornady ammo later I'm sure it will be even better.
