Finally got to the range today to shoot my new Rock River Entry Tactical (darn job/family cutting into my range time!) 220 rounds with no issues at all. Here's the breakdown:
50 rounds Hornady Steel Match .223
20 rounds American Eagle .223
70 rounds Tula .223 steel case
60 rounds Federal XM193 5.56
20 rounds mixed Tula .223 and Federal 5.56 in the same mag
Used 2 new p-mags, 2 surplus p-mags and the factory aluminum mag
Here's the best group (50 yards) with iron sights. I'm happy with it considering it's been 20 years since I last shot with irons.
The scope is a cheap Barska. It actually performed well. Only used Tula with the scope. Best group at 100 yards was 2". I'm sure the rifle will beat RRAs 1 1/2" guarantee for the chrome lined barrel. No pics, phone battery died.
Needless to say I'm pretty happy with the gun. Taking my 11 year old son (shooting his 10/22) to the range with me only made the day better!
