Using It for the past two months and doing his job. 5 stars for me
I never received item. They said it was returned by my post office but it never left China. Then received an email asking for $12 for shipping again.
Accidentally dropped it whilst fitting and it shattered into pieces.
Very brittle, useless on any gun like that.
Just havent recieved it yet... ill change to 5 star when i recieve it
Nice product.. Now im not worried to slap my charging handle..
