Swiss Arms doesn't have a chrome lined barrel! That sucks!

Like said barrel steel quality is very important as is hardening. Hammer forging is a great method. Think of the yugo ak's and rpk's in the middle east, no chrome lining and still ready to fight the next war

Any good quality AR barrel is cold hammer forged and chrome lined
I think the swiss wanted accuracy, like valmet did with their m76. Even most norinco barrels are hammer forged.

My two cents is that chrome lining is wank for target shooting anyway and presumably we are target shooters.
Chrome lining a .22 barrel was invented during the Vietnam War iirc and it was considered quite an achievement at the time, the problem is getting the chrome the right thickness. You can get it the right thickness for military-grade accuracy but target shooting is a different situation.
Personally I think only Colt's have ever really done it well, I had a Colt LW Sporter that was truly accurate but I've had other makes of barrel (e.g. Bushmaster) and they were all crap in the accuracy dept.
It was really designed to protect against corrosion with corrosive ammo and poor maintenance/harsh environments.
For target shooters it's a non-issue. We can use all kinds of exotic stuff the military can't afford, stainless steel barrels, cyrogenics, etc.
While I'm on the subject, 1/7 barrels are also completely pointless for civilian users. "OMG, my rifle has a 1/10 twist barrel" Doesn't matter unless you're planning on using tracer or 80gr SMK. Even Colt's tried to talk the DoD out of using 1/7 barrels.
The other thing I'm often bemused by are people who buy guns like Swiss Arms guns and then run the cheapest nastiest ammo they can find through them.

I know serious (and I do mean serious) target shooters in Switzerland who replace them after as little as 3,000. Depends entirely on the ammo being used, some of this Russian crap will wreck a barrel in as little as 2,000 rounds. Also depends on what you mean by a "drop off" in accuracy.
Also depends on other factors, like how quickly you shoot the rifle.

What the Swiss Arms guns? No they're not. Maybe you got lucky but they're not designed to be.
No question, type of AMMO always has an affect on barrel life, always. Most serious shooters in CH will let them go to 10k, service rifles go longer. Chrome lining wouldn't extend the barrel life on these...... it may have been tried. Not everything tried makes it to the internet.

It most definitely is not. I've got one, and the test target shows 1.33 MOA. I've tried RUAG match ammo (basically GP90 but with a Sierra MK bullet) through it and Federal GM and I can't even get that.
The average grouping with dirtybird factory ammo from my rifle is 1.5" at 100 meters. Sometimes better, sometimes slightly worse but no more than 2". The barrel, a 1:10 twist, has 3000 plus rounds through it and still looks new.
With handloads I have seen guys hold the 1 MOA average, but you can forget that with factory.
American Eagle 100 meters shot with Acog.
At 300 meters 15 shot group American Eagle.
388 meters 10 rounds American Eagle.
Bottom line: If your Swiss Arms won't shoot the problem is you.

Hmmm....where and how far do you shoot?
I can assure you the Swiss 1:10 barrels will not stabilize a bullet like the 77 gr. Sierra match king.
If you believe a bullet design like that does not matter at long range, you might just want to stick to that Norinco ammo you are disparaging....

77gr OTM also smashes things made of meat really well in close.

Nice shooting J996. You're helping keep the Rifleman tradition alive one round at a time!
