    I've made quite a few 3 gun race guns and find that, if left unmodified, eventually most of the bolt carriers crack on high round count guns - especially if the gun is tuned for birdshot, then used with 3" turkey loads, or buckshot for some match stages. The solution that works 100% for my guns is to drill out the dimples right away before the carrier cracks. Remove the original op rod. I put in a brass insert, (shown in the picture) then TIG weld up the holes. With the brass plug in place during welding, the threads are pretty good after welding. I clean up the threads with a tap. I

    Magwell is R&R as is the pistol grip adapter. They make great stuff. The hand guard is 1.875 O.D. x .060" wall carbon fiber tube. Readily available on Ebay. Some machining and aluminum welding to make the tube ends, then hard anodized. When machining the carbon fiber I wear a respirator and use a vacuum to suck up the dust. Stuff is bad news to breathe. Carbide cuts it fine. I get a close a possible with a Dremel cut off wheel, then machine the rest with a carbide end mill.

    No plans for now. Way too much work.

    All I can say is the machining makes a lot of chips. I've been wanting to do a hinged dust cover for a long time. It's been an evolution -- Here's one of my other S12s - I didn't like the optic height over bore (which is at the minimum to get the dust cover off). I like the hinged dust cover and offset stock much better - less recoil, easier to take apart, any rail mount optic fits, better height over bore and better optic placement on the rail.

    Hi all- here is my latest race S12 build - My best ever so far and only one in existence. Has a railed/hinged dust cover I machined. I also made the carbon fiber hand guard and the stock adapter. The stock is offset up so the center line of your shoulder is in the center line of the bore. Has a 1" recoil pad and the stock is shortened so the trigger pull length is exactly the same as an AR15. . The barrel is 16" and internally threaded for chokes with a pinned and welded compensator for a legal overall length. The axis pins are machined from polished 4130 steel and are keyed

    It's so simple it's not necessary to send it to a smith. Just find someone with good TIG skills. Here's a tip. If you make a very tight fitting copper plug, i've found that after welding, the plug can be hard to remove. and you have to drive it out/ The tool shown here is an aluminum sleeve with piece if 1/2" copper pipe over it. The shoulder on the aluminum sleeve allows you to put the plug into the barrel for a super tight fit. But when it comes time to remove it, the aluminum pulls out of the copper, then the copper sleeve can easily be removed.

    I've personally "stood guard " for my two daughters at the restrooms - anyone with a Y chromosome who decided to "identify" as female that day would have to get through me first. Thankfully it never happened or I would have suddenly identified as female too and it would have gotten way ugly in the women's room.

    This State is a mess. . City of Los Angeles, Sunnyvale and San Francisco already passed bans on possession of any mag holding over 10 rounds. Total population of over 5 million. Number of magazines turned in so far = zero. Zero compliance rate. No reasonable way to drive from San Diego north without passing through a "banned" zone. However enforcement is also zero. In 1990 California banned "assault weapons" and required registration. 7,000 were registered out of an estimated 300,000. A 2% compliance rate. Once banned, everyone wanted one so perhaps a million more AKs and

    I live in this messed up state and that is just the tip of the anti-gun iceberg. there are 7 different anti-gun measures in the pipeline. However there is some hope --- What happened here recently is that our Governor vetoed some anti-gun bills (he's a Democrat but said that his father told him "never mess with a man's wife or his gun"). so after that defeat for the anti-gunners, Bloomberg bankrolled paid signature gatherers to get signatures to put it on the ballot as a Proposition for the people to vote upon. Newscum is just the front man. There's reason to believe (or at least hope) th

    The tolerance between the end of the piston rod (what you are calling a bolt carrier extension), the puck and the gas adjuster plug is forgiving. Obviously there must be clearance so that when the bolt is fully forward, the puck is not hitting the gas adjuster plug . 1) Put the bolt into battery (farthest forward position of the piston rod), 2) push the puck against the piston rod (farthest rearward position of the puck). 3) now measure the distance from the front face of the puck to the end of the gas block. You should have between about 0.800" and 0.900" with a stock gas puc

    I agree with some of the other posts - If there were a one gun only law -- -- Since "gun" is the receiver, I'd take an AR lower with .22, .223, .300 Blackout, 7.62x39, and .50 Beo rifle uppers, plus a few pistol uppers as well. Ought to pretty much cover it. Even heard there is now a .410 AR upper, I'll take one of those too. That's after the boating accident of course where everything else was tragically lost.

    Agreed on the rail "flexing" in the mount - too much leverage on a small area - Had a C More slide ride on a similar one and it flexed too much. Use one of the shorter mounts - or buy that one from CSS and cut it down. CSS is always a pleasure to do business with though.

    The angled part of the hood times the rotation of the bolt into the front trunion. There is a lot of bad advice in the web about filing the lugs to set headspace. I prefer to do it right and simply press out the barrel slightly, then press it back in again setting the headspace by proper barrel insertion into the trunion. Press a little, check it, press again, check it, until it headpsaces. Once it is headspaced, it's very possible that the barrel retaining pin may not quite not up with the groove in the new barrel. Redrill it using the trunion as a drill guide and use a metric coile

    I get what you're saying, but on the other hand I'm a competitive shooter and end up changing lots things for competitive advantage. A stock weapon is just a "different" weapon to me so no different conceptually from picking of a Glock after shooting a 1911, or an AK after shooing an AR. My S12 race guns don't even resemble anything close to stock. I'd lose if I had a iron sights, rock n lock mags and an AK style safety.

    Can be a major hassle. Some come out just fine - others will not come out with a punch. I made a fixture in an arbor press. Works every time. You have to clearance the tooling so the part lays flat - also have a hole in it for the pin to fall out. use a short punch pin.

    No danger of Obama on the supreme court -- He wouldn't accept - he's a narcissist -- he'll go on the speaking circuit and book tour and make millions. If she wins though, we may get someone even worse.

    this already passed in Seattle -- NRA appealed and lost. It went into effect Jan. 1. This bill doesn't allow you to "roll your own" - it says quote --- " As used in this section, "ammunition" means cartridge cases, primers, bullets, or propellant powder designed for use in any firearm." so in theory it would be more expensive to roll you own if you had to pay 5 cents on a bullet, 5 cents on a primer, and 5 cents on any new brass, and cents on powder (not sure how they are going to figure that one ) - if I lived there I guess I'd develop a really hot load with 7,000 grains a

    I think you're confused on the gas block vent hole. When viewed directly from the side it looks like it's partially covered, but if you look carefully you will see that It's drilled at an angle upwards - it does not cowitness with anything.
  22. MLM0358
    Probably nothing to fix. All Looks normal to me. I use an allen key to check/clean the ports. Since it has a 90 degree bend it's a handy tool that's already on the workbench.. You have four ports. One is mostly hidden, but can just barely be seen. You will find it with the allen wrench.
  23. MLM0358
    Welcome. Agree with JohnnyE - DO NOT drill gas ports until you fully understand what is going on. it MAY be necessary, but rare. I have built numerous that run (after some minor work) flawlessly on Federal bulk with stock three and four ports - no drilling required.
