This BCG is very well made. I never had any problems with it, it cycles smooth and very reliable in my 6.5 Creedmoor rifle. Actually, I have several "Odin Works" BCGs, I tried them with 5,56 and with 300 AAC Blackout, all of them run just great! "Odin Works" BCG is not the cheapest BCG that you can buy, but yet it is pretty affordable. Also, I'm personally enjoying having BCG and other parts with His name on it in my rifle. Gods Bless America!

The bolt head leaves brass shavings all over inside the chamber and on the bolt head. Ive generally have heard odin work produces decent quality products but this is not acceptable for the price, quite possibly a lemon
