I have a mini 14 - 186 series GB model and wanted to put a can on it. So i ordered a Hughes Precision adapter in 9/16 ×24 to ½ x 28. This is not my 1st can or project and I have over 50 years experience with firearms including cans and class 3. I have always checked alignment with a rod and visually b4 firing any can, since my 1st purchase many years ago. The adapter was installed just past hand tight with a lite amount of rock-set and allowed to cure for a week. Checked alignment with a 22 caliber rod and visually checked. Fired a shot checked the can for tightness and fired a few more shots as I was zeroing a red dot. Checked can to adapter again and snugged it with my hand (I use silicon can covers). Fired a few more shots and checked the can to ensure no walk. Then fired 3 shots and my can fell off the gun! 1st thing I thought was baffle strike, but there was none. look at the attached picks and its obvious theres an issue with the adapter. I reached out to Hughes precision and simply asked for a full refund providing pictures. Instead of a thank you for reaching out and letting us know I get treated like crap and get a partial refund on a defective item with only 14 shots fired. This post is for Tina at Hughes precision who wouldn’t refund my shipping fee, bless her heart! Didn’t offer me an apology, a replacement nada!
