I am interested in milling out my own muzzle brake and don't know what the best thread is. I think my saiga 12 is like 22 x .75 tpi. It came threaded already, is that correct? is that the best shotgun thread? If I want to make a new brake for my saiga what plug tap do i need to fit the factory threads?

I have no idea how to install the barrel extension and do it right. Then does that fit the upper for an Ar receiver for 5.56? I just did some research and it looks like I can definitely do this if I use the machining equipment here at college. Can I do this by means of hand threading at all? Should I secure the Barrel extension onto the barrel with blue or red loctite? Could you please explain what you mean by threading the chamber end and such?

This is a barrel blank for a 5.45 with a 1 in 7 twist, i need it turned to fit an AR upper receiver, and the barrel itself is 1" in diameter overall, I was actually thinking about maybe doing this particular gun as being blowback operated. and milling out part of the upper to put a charging handle on the left side of the receiver versus the standard ar charging handle. Thoughts please?

I'm new an haven't found my way around yet. I want to buy a 5.45 barrel blank but it is unturned and I have a lathe. What do I need to do in order to finish this rifle barrel into a mountable barrel? I was told something about tapering and crowning and such but I guess I am looking for the steps and what they involve. Any help is greatly appreciated.

Well, worked amazingly, don't have any pictures but it was a dream. Had less recoil than a 20 gauge with birdshot, even when I put slugs through it and compared the two, The vote was unanimous that I had the lightest recoil shotgun there and I did an amazing job with it. I'm not going to change a thing on it. Needless to say I am quite proud of it.

I have a few suggestions, Use a .45 acp 1911 recoil spring, use hooks physics laws to determine the amount of pressure you want to relieve from the recoil and then measure and cut accordingly. Sunday is the test, the spring constant that mine has is 279, that is a lot, i had to place a washer in the recoil pad and loctite everything on as well as epoxy an extra layer, I see another spot in the action that i can place another buffer or compression spring, I will be testing all of my designs and work on sunday and posting pictures as soon as I test it and fine tune it. Any questions just ask.

Thanks Guys,Here's what I have done to it thus far. I custom ordered a compression spring for the stock and milled out two 2-inch slots in the collapsible stock to give it two length adjustments with a travel of 2 inches upon firing. This is a 14 pound spring, i also have a 9 and a 20 pound spring for it, The gas system is a 6 slot so I shouldn't have to worry about cycling issues, if I do I will port that out as well, I polished the trigger and buffered the backplate to take some pressure off it, also i ordered a recoil spring that is 2 pounds stiffer than the stock one and the chambering is

Thanks, I am an engineering Physics student and designed my own system for it. I am also looking for a compensator, i recently contacted barret and asked about getting one of theirs for it. I shoot pretty much everything through it without a problem, I am just trying to maximize the performance of it. I have a collapsible stock on mine with two recoil springs i specially ordered, even on it's lowest gas setting i can shoot low brass. This week I will finish milling a couple parts for it and I want this to be the last step.

I'm just wondering what any of you have tried for recoil reduction of the Saiga 12? I've done a lot with mine and am just looking for some ideas as to what others have done with theirs.
