First time out with my then new sbe 3 at the clays range it fell off the golf cart at full speed onto the sharp gravel road and got some nice deep gouges. Nothing to be done and it still works fine so it doesnt really matter.
Ive got a couple m4's and the price wasnt enough to be any real concern. Quality is worth the cost. Most people who complain that something isnt worth the cost do so because they cant afford.
I had my m4 entry threaded for chokes by briley so its the same pattern as my full size m4 not rem chokes. I did it because I wanted to be able mount my salvo. I think it was a $150 and I have absolutley no regrets.
