Does the fluted flash can come off?

Can’t beat this upper for the price
Upper was everything I needed, has run flawlessly and looks awesome. Wasn’t a huge fan of the bcg finish but have not had any issues with it. Would definitely recommend this product.

After patiently waiting for this upper, I would highly recommend!! I had heard stories of barrels less than 10.5 having reliability issues. I have found that to NOT be the case with this upper. After properly lubing it, took it to the range and ran it through it's paces. Chugged right along with any ammo I fed it. It ate up 200+ rounds of steel case too!! With a Shockwave blade equipped pistol lower, it's the perfect size for bedside or truck use. I would have given it 5 stars had I been able to get it for the same price as Black Friday special. I'll be buying another when the price drops again!!!!
