Re: HS Precision Bottom metal install
I just put two of these into McM stocks. They are NOT drop ins and I'm no gunsmith. But I was able to fit them in using a dremel tool and some patience. In addition to stock inletting, I had to mill a little bit of metal where the trigger guard rubbed against my CG Jackson trigger. Then I had to mill a little bit off the front of the magazine lip where it rubbed against the action and would not seat. Each assembly took me over an hour to complete...but I'm not practiced at this sort of stuff.
Next, I seated bullets into the magazine and accidently dropped it to the floor. I noticed that the rounds kind of popped out half way...and that bothered me. So, I took some needle-nosed pliers and carefully bent the lips of the magazine down.
After all that, I am very happy with the fit and function of the rifle. It feeds flawlessly now and the rounds stay securely in the magazine when it is dropped.
I originally bought the HS-Precision because I like how the 4-round magazine sits flush against the stock as opposed to the AICS which sticks out and looks wierd.
I do also have the AICS assembly in my tube gun. It IS a better magazine for sure, but the HS Precision works great after the mods I did.
PS. These are center-feed magazines, WAY more reliable that the standard BDL bottom metal.
