Re barrel an SR762?

I've an SR762 that I would like to re-barrel with a longer heavier stainless Barrel.

Because I'm in Massachusetts the stock barrel which comes threaded had to either be shortened, have the threads ground off or put a muzzle break on and weld it!

Any thoughts? Am I crazy?

That would be a tough one. First I am not sure what barrel is compatible with the sr762. Its not like the 308 ar platform has a spec to follow like the ar15 has. Second the rifle being gas piston is proprietary to the sr762, which poses another problem retrofitting another barrel to make it work. All this could probably be accomplished, however it would get real expensive.

My thoughts it would be cheaper to buy a dpms lr308 heavy barrel rifle, they are highly accurate, own a few. That makes alot more financial sense.

I feel sorry for you guys, get out while you still can. Well, either get a custom built, or settle for something else is you guys only option.

Well, you may get creative, find an upper thats compatible with the ruger lower, it appears the same outside appearance as the armalite pattern, although I do not know for sure with out personal inspection, If that will work with that lower, you could then buy an upper reciever, bolt carrier group, barrel, and construct a direct impingement upper. As long as the parts are in harmony with each other. I have never seen it done, but if I was in that particular situation, I may give it a try. Research, research, research.

Lots of luck. I have been asking Ruger when they are going to offer a longer barrel for the SR 762. I have had mine since 2014 and seem to ask Ruger every couple of months but all I get is that any replacement barrel has to be installed by Ruger or it voids the warranty. I would really rather have a 18" to 20" for improved accuracy especially at distance.

I don't know if that will happen. A 16" .308 barrel will do just fine at distance.

Possible ? Yes.
Really Expensive? Absolutely.

From a technical viewpoint it can be done. The question is - "At what expense?" and Is it worth it ?

Because it's an AR type platform with the locking lugs cut into the barrel extension the first real hurdle to get over is the breach end of the barrel. You would need a stainless barrel, of the desire length, with the proper chamber, with the proper bore & twist rate, that had the correct barrel extension to mate with BOTH the bolt and the receiver.
After you got past that issue, you would need a gas port drilled in the right location to match up with the gas piston and related parts.

Could it be done ? Sure. Could it be done for a reasonable amount of money ? Not on your life.
