Since you are looking into high grade target guns, you could easily send your new MKII to Clark Custom Guns and have them conpletely fit it out for target work. Such a gun will shoot with the best of them: mine does.

You can send your 77/22 barreled action to Randy at CPC and get him to work his magic: bolt re-work, barrel set-back, and rechambering. That will fix almost all of the objecitons. It did for me. I have both a CZ and a Ruger. The CZ shot like crazy right out of the box.

Cure most of your problems in one fell swoop by having it rechambered to .22 K-Hornet. That even works through Ruger magazines. The .22 Hornet has very thin necks, so I never buy nickeled cases. As stated above, the Remington cases have just a little more capacity, so are my favorite, too...

There really is no reason to get anal about cleaning all of this stuff. The gas piston is a self-cleaning design with a self-lubing coating and the op rod is likewise. The bolt and carrier operate very cleanly by comparison to an AR-15 because this gun is not a direct impingement system. Leave...

They may have a finish that varies a little in color. For example, parkerizing can range a little and can be made in several colors. This is not necessarily parkerizing, but that would be an easy example. Mine is black.

No, but I'd be very happy with a .22LR upper.

I have an older M77-Hornet. After you buy it, send the barreled action to Randy at CPC (Connecticut Precision Chambering) and have him work his magic on it. He works wonders on these things. He will even convert it to a K-Hornet, if you want, that works well with factory magazines.

I would be tempted to try a soaking in a carburetor cleaner that was labeled as a carbon remover. No sprays, get a gallon can of Gunk with the parts basket in it.

By all means, do disassemble the outfit and check these things: 1-The alignment of the screw holes in relationship to the apparent centerline of the receiver and that whole relationship to the centerline of the barrel. Just because it came from the factory, it does not have to be right. I have...

Try any of the following: 6.5mm Rem Mag .358 Rem Mag 7x61 Sharpe & Hart (an old favorite of mine, with freebore, too) Maybe .30-.338, which is like a 7mm RM necked up.

Well, you have run up against the classic .257 Roberts problem: the barrel twist is sufficient for the shorter 117 RN bullet, but not quite tight enough for a longer, pointed bullet. This has been going on for 40 years that I know of. You can rebarrel the rifle with a tighter twist, find a...

Well, my SR-556 is a splendid firearm and well built. I shot an M1-A for years and so am familiar with gas piston-type rifles. So far this thing seems very reliable and took to an aftermarket Timney trigger just fine.

well, you have stumbled across one of the dilemmas of 10/22 ownership: whose barrel out-shoots whose. The factory 10/22T barrels are quite good as-is and many people are happy with them. The older versions of this barrel had standard, commercial chambers and would benefit from being set back...

I must agree with the previous writer who concluded that the firing pin protrusion is too long. Years ago, .22s were made with lots of firing pin protrusion and this sort of damage was very common. Someone even made a little cartridge shaped steel insert with which one could iron out the...

"...I want the most accurate of the Mark III for target..." Buy the cheapest one (stainless or blue, your choice) and send it to Clark for a complete rework. Then, you will have a first-rate target gun. Otherwise, buy one of the longer barreled models with target sights and try different ammo...
