Awesome product - Yankee Hill Machine QD Blast Deflector 5.56mm/.30 Caliber YHM-3130

I bought this with YHM flash hider for a pistol build. The build is going to be a suppressor dedicated build once the nfa paperwork clears. I decided to go with an 11.5 barrel length for reliability and still be compact with a can on the end. With my long arms I found 10 inch rails to be too short so I went with a 12 inch rail. The blast deflector sticks out the end of the rail about 1/8 inch and looks pretty clean. Functionality it works great and will go on my 16 inch upper when I go to an indoor range. While I agree with the previous review that it mitigates some of the muzzle device's effectiveness, that's to be expected. I definitely don't call that a negative. Anything you put around the end of a muzzle device with the exception to a suppressor is going to do that! Not to mention it's cheaper then all the ones I've seen that mount to a suppressor compatible muzzle device.
