I took the mini-14 out today after my modifications. I added an AK muzzlebrake, Ultimak Rail and Hakko Tacpoint. I had 5 cold shots in a 2 inch group at 100yards using Sellior and Bellot range fodder. That was my best group of the day. I haven't had a trigger job either. I'm impressed by the muzzlebrake. Before the AK brake I had on a Clark Gun Barrel Stabilizer. It worked but it made the mini so heavy that it basically became an emplaced weapon. I wanted something portable. Over at the perfect union forum guys were raving over muzzlebrakes reducing groups. So I went over to Bushmaster and purchased their AK brake. I went with the AK because the other brakes added like 4 inches to the barrel. I wanted to keep the mini as compact as I could. The AK brake fits over the factory front sight. Punch out the factory pin, slip on the AK brake, punch in the supplied replacement pin, and loctite 2 locking screws and you're done. It was super easy. I was also looking for a scout configuration so I bought the Ultimak. Forum member Variable1 had some Hakko Tacpoints (Aimpoint 700 clone) for $100 so I figured why not? The Ultimak rail is solid. It replaces the top of the gas block and also clamps to the barrel between the barrel and op rod. The Hakko has been a nice surprise. The dot is not blurred at the highest setting and held zero all day. I think the combination of the muzzlebrake and ultimak rail has greatly helped reduce my groups. The muzzlebrake adds weight to the end (like the GBS but without all that weight) while the Ultimak seems to make the barrel more rigid because of the clamp. I think both factors limits the amount of barrel whip so accuracy is enhanced. I still have the problem of wandering accuracy if I fire off 30rnds at once. But now, instead of peppering a 8.5X11 sheet of paper like a shotgun, they stay in one quarter of the paper. If anyone is looking for a quick accuracy mod, take a look at the AK muzzle brake and Ultimak rail. Now I'm contemplating a trigger job and new gas bushing (the ranch models launch brass like crazy!!)
