Has any one re barreled their Swiss arms rifle?

I know that there are OEM Swiss barrels out there in a 1 in 7” twist. But that’s not really what I want to do.

What I am considering is removing the old barrel and having a 1 in 8” twist Krieger fitted to the Swiss receiver.

Will this get me a sub moa Swiss?
Any reason why this may not work?
Any suggestions on how to make this project better?

Thanks,

TK

Aren't they already sub-moa?

Some out there may be, but mine is not.

The load I currently shoot: 69Gr Matchking and H-335 averages about 1.25moa.

Last weekend I shot out to 700m quite sucessfully with this combination. Of course this got me thinking that it would be easier to make hits at this distance with a more accurate swiss.

I am wondering, what is the weak link in the Swiss Arms system? Is it the Barrel? Or possibly the reciever; or the way the forearm and gas block are attached?

Would a new barrel make this rifle into a real shooter, or would one of the other componants hold the rifle at the 1.25 MOA mark?

Yep they are all service rifles, and regardless of the modifications made, they may not meet your chriteria of a "Precision rifle".

If it is a reasonably common modification to rebarrel an AR-15 or an M1A1, why can't or shouldnt I rebarrel my Swiss arms to meet MY needs?

My intention is not to build a 1/2MOA capable semi auto. Only to improve somewhat on the factory product.

I get what you are saying TangoKilo but TDC has a point. While most service rifle providers and particularly HK and Swiss have high quality control the reality is the specs for these rifles are not sub-MOA. The idea is to hit centre body mass at 100-300 metres on average and to be able to go through hell to do it.

You could spend a lot of time and a lot of money trying to make your Swiss sub-MOA but in the end still have a rifle that structurally was never intended for that mission. The sniper variants were (are) intended for that mission and your specs so maybe an HK SL8 might be what you are looking for.

Its kind of like taking a mini-van (a really nice mini-van) and trying to make it into a sports car. But its your time and money. So follow UncleWalther's advice and PM the guy he was talking about and see where it goes. If you do it then make sure you post a range report and many pictures to let us know how you did it.

All the best and good luck.
 
As posted above my by severus, the system has limitations. The Swiss is no doubt the most accurate production service rifle available. The factory accuracy requirements are astounding. As Koldt posted above, its the shooter that makes the difference. Try improving your skills before wasting money trying to squeeze another 1/10 of an inch out of the rifle.

some of the best quality barrels found on any rifle are used on the Sigs...not sure what, if anything you'd be improving.
I've seen some phenominal mechanical accuracy from mine - it just doesn't matter if I can't hold for it.

If you were to have a barrel made for one, I'm certain the custom, one off profile would cost you a pretty penny. You may want to engage someone like Spartan Precision to handle this.
 
what's the barrel twist in your rifle and what ammo are you using? Finding the right ammo combo may give you the results you are looking for. If you are shooting the 1/10 twist try the RUAG gp 90, if 1/7 twist find some hornady tap or match 75 grain and see how she does, If you need better precision Anschutz is making a 1770 for a mere 2200 you will get a .223 sub moa and a great rifle to boot.
