  1. I always take with me to competitions full set of spare parts.

    That can break down anytime and anywhere, it is impossible to predict.

    Here, for example, some minor damage my shotgun and my friends:

    That's a serious breakdown:

    But the overall wear a shotgun after 20000 shots:

  2. Well, I've pretty much looked everywhere, but no Saiga 12 spare parts are available until sometime next year. However...I love a good plan. As it happens, my dentist is also an avid shooter and he knows an oral surgeon who owns this super cool 7 axis computer miniature milling machine that sits around when not making quartz or gold replacement crowns. Cost like $120 grand or so.

     

    How it works is like science fiction. You place the part you want duplicated down like to .0001 of an inch into a secure frame and some lasers scan the part. Then you put in a billet of hard gold or very hard quartz or plastic in another jig and the machine then duplicates the part, down to the smallest detail. I don't know if the steel would be designed to mill out replacement 4140-4130 shotgun parts.

     

    Anyhow, the mind boggles, at least my feeble mind. I will be contacting the oral surgeon in question and ask him if his neat 7 axis milling machine would be able to turn out 4140 billet gun parts and if he would be willing to rent out his machine? Bolt heads, extractors, plungers, firing pins and other Saiga- specific parts come to mind. This would also work with all the other Saigas. $expensive$ fur sure.

     

    What do you think? Am I wasting my time or not? HB of CJ (old coot) How much would you pay?

     

    It is important to take high-quality steel

    and do the right heat treatment. This is

    important, do not forget about it.

  3. Some people use Red Star Arms Triggers, they are adjustable. Do reseach before buying one, sometimes you have to modify the trigger or safety to make them fit in certain AKs. I have heard good thing about Texas Triggers as an option besides the Tapco Trigger.

     

    Adjusting screws unscrew during firing spontaneously. And if you screw them on Loctite, then later, if necessary, unscrew them is impossible.

  4. AK can be operated without any lubrication and more than 1000 shots. This is exactly and tested more than once.

    If you have a weapon for SHTF situation, you have a gun "on every day." And for hunting and for sport and for self-defense.

    For me, as a lot of shooting, life and simplicity of weapons is very important.

     

    ps in a short time for the sport going to buy AR-15. Let's see how long it will last.

  5. Translate the main points.

    Saiga 7,62 photo from the article and my shotgun 12ga

     

    1. 2-3K shots - to hammer appeared burrs that clung to the sear and trigger stuck on it. They were removed needle files.

    2. 8-10K shots - Round sear a single lamp. Started double firing.

     

    Fixed in the grip of needle files.

    3. After 10K rounds - broken sear a single lamp.

    This happens about every 12-15K

     

    4. Wear sleeve trigger

    5. Depreciation ledge hammer. Fixed welding.

    6. After a 20-25K rounds - break the firing pin and extractor tooth.

    95525241.jpg

     

     

    Broken axle hole hammer and trigger. You need to timely change the axis that would avoid this.

    95525253.jpg

     

     

     

    7. After 40K rounds - broken rail on a moving bolt carrier. The bolt carrier began to fall out of the receiver. Saiga sending in for repair.

     

     

     

    Hammer springs are normal.

    The gas piston has a sink.

    Status of the barrel is satisfactory, but inside there is a sink

    Grouping to 50m

    Where there are any statistics on the AR-15?

  6. I do not see a problem. Wear is

    minimal. This Saiga still get your

    grandchildren.

    Here you can see the wear after 20K

    rounds of heavy http://sergii-guns-r....com/71675.html

    With all respect to you, In my opinion what your gun shows is acceptable wear. What the OP has is not however.

     

    I have had a 4 port gun since '08 and have been beating the cock out of it damn near every time I bring it out. I have the elongation on the bolt carrier from the bolt, wear marks on the bolt, extractor, and FCG, but nothing along the lines of what is being shown here on the trunnion.

     

    Thats not normal IMHO.

     

    I probably have 1k rounds of 3" magnums through mine and my rear trunnion looks better than that(keep in mind this is just me including the goose loads, not the rem sluggers, 00 buck, trap loads, or occasional turkey load thrown through my gun).

     

    None of my 3 S-12s exhibit this kind of wear.

     

    I highly recommend looking into methods of cutting back on gas, and possibly a stronger recoil spring.

     

    My gun has five gas ports. Beat the bolt on the rear of the receiver - this is normal. This is not a problem. Safety margin at the receiver is huge. From the aesthetic side of course is not very pleasant.

     

    I have my own requirements for the gun:

    1. It should shoot bullets of 28-44gm.

    2. It must shoot in any frost.

    3. It must shoot in any situation. Regardless of the butt pressed against the shoulder or not.

    4. All this must be done without any additional adjustments in the process of shooting.

     

    So I will not limit the amount of gases or increase the return spring.

     

    In this mode, the gun I live 1.5-2 years. During this time the fires around 20K, and then sent to preventive maintenance.

     

    The average user does not have to worry about this deterioration. Especially Saiga has control of gases.
