Sorry, didn’t check on the thread for obviously a long time. The aluminum body of the forend needed a lot of fitting. I had to cut the rear portion away to form the rear key, remove the rear m-lok rails to fit over the trunion and remove a portion of the inner walls of the front m-Lok to fit over the gas piston. Notch out a part for the stock forend retainer, and machine one of the magpul clamps (threaded side) to form the front key. If I could do it over again, I would have fashioned an offset rear key and lowered the forend by 3mm so I could access the gas adjustment without using a punch or tool.
I’ve since cerakoted the aluminum and added a brake. Shoots amazing after a little tuning. [img] https://i.imgur.com/08NZXw2.jpg[/img]
