Gunsmithing HS Precision PSS stock modification to MTU bbl and oversized lug question?

[Punisher29073]

I have picked up an R700 barreled action with an MTU barrel and an oversized lug. I am partial to the PSS stocks. They just fit me well. I believe the barrel channel is able to be opened up enough. The front lug is what I am concerned with. The thickness I'd easy to adjust for, the depth on the other hand, will be difficult to do without a mill.

If anyone has some pointers or experience with this type of modification, please share your wisdom. I am a pretty handy guy and like to do all the work I can myself.

Tag for info. I am looking at doing the same thing.

Punisher what is the od of your barrel at the muzzle?

I just opened one up for a thicker lug for a family member. If your lug is too long, you're bottoming out into aluminum. You will need a mill if you don't want it to look like kindergarten shop class.

What are the chances of me being able to do it on drill press with and end bit? Working slowly of course.

Why don't you just file the bottom of the lug? Easy done. Guys mill them short for aics chassis all the time

I am hesitant to modify the barreled action. It is an APA and this stock may be temporary. I was thinking it may go into a chassis system eventually. Are you saying that if I did put it in an AICS, I would have to file it down too! If so, do you know how short it needs to be?

Not very good. lol. The problem is that you have to remove the material at least flush with the current lug abutment. Once you start cutting away at it on a drill press, you're very likely to chatter around and take meat off of the lug abutment. Then you gotta file it smooth again, or try to come up with some way to clean it up squarely. Then after you spend a few hours cleaning it up, you'll look down in the bottom of the hole and wonder when a beaver got a hold of your stock.

In the time it would take you to do this and try to fix it red-neck style, you could take it to a local machine shop and pay $20 for someone to make a 10 minute job out of it.

Cut off a bit of the lug length, it won't hurt anything. I did the same thing with my R700 in a HS stock with oversized lug.

Just an update. I was able to open the barrel channel up for the MTU barrel with no problem after chipping out the bedding someone prior to me had done down the entire length of the stock. The lug cavity was also large enough to hold the oversized lug after digging the bedding compound out. I filled in a couple chips with JB Weld. I added some grip with some paint on bedliner at the grip and front hand position. This stuff gives it enough texture so that it isnt smooth, but you can only see it in the finish if you are looking for it. Then I duracoated the entire thing Woodlands Tac brown(OAF baby!) and sprayed it with black webbing. After that cured for a day I clear coated it with duracoat. A word of warning, If you put too much clear duracoat on it will make the webbing run a bit. This happened in two small spots.
Over all I am tickled with how it turned out.

This the stock in progress. I will post pics of the finished gun when the front rail gets here.
This is how it shot.
