Gemtech Series Flash Hider 7.62 ETM 5/8x24

The item was delivered promptly, and as ordered. Unfortunately, I did not realize these muzzle devices will not fit my (older) model of suppressor. I realized too late that I could not return the two that I ordered to Bud's inasmuch the return policy says that only defective products may be returned and then only within ten days of receipt. I was not able to find out that I had ordered the wrong parts until too late, and they were not defective - just the wrong part for me. My bad, but now I own two muzzle devices that I cannot use. BTW, the Gemtech website is less than useless and customer service will not respond to emails. I figured that Gemtech may make a substitute endplate adapter that will retrofit to these newer tapered muzzle devices. I'd rather have a taper-mount QD. There's nothing on Gemtech's website that gives any good information in that regard and, like I said, I can't get any information from Gemtech . . . yet. Maybe that's all too much information but I wanted to offer this as a warning to those who may be trying to find Gemtech QD mounts - make sure you have the information you need before you order.
