Titanium cylinders won't develop peening at the stop notches. That's the only real advantage.and lightens the gun up weight wiseWhich is not especially advantageous. Would it be more advantageous in a gun shooting minor? Seems like weight might be helpful in .45. Does it really matter in a 9mm?

It is quantifiable if someone cared to do it. Set up a series of courses and shoot them with two guns. The trick is finding someone who wants to take the time to do it. It will also vary by course. Short wide open stages favor the iron sight gun more than long tight shots. Weak hand stages also seem easier with irons to me. But that's because it takes me longer to find the dot because I don't practice enough with it.

I hit up Smith & Wesson every year at SHOT to make this. You're welcome. Actually the response I got every year was they would make them if they could presell "x" amount. I doubt Jerry guaranteed whatever that amount was. As for Jerry driving the BOD to do anything that's kind of funny. Jerry is good at a great many things but herding cats isn't one of them.

I'm in. Shooting Limited (I think) Saturday.

BTW, the biggest increase in barrel life in the ACR comes from the piston system. Nothing at all to do with the coating. The piston system lowers heat buildup in full auto or extended firing strings. Normally not a significant concern for three gunners.

JP, Nordic, Krieger, or a dozen others will make terrific barrels. Trying to ask a bunch or AR guys which one will be the best in an ACR is probably not going to get you the best result. All of them will shoot fine and everyone has their favorites. Your other big limiting factor (I'm guessing) will be the barrel diameter at the gas port. This is where the piston system will attach. It has to be "x" diameter in order to work. I don't know if that .750 or something else with the ACR. make sure whatever barrel you order is right because you don't have any options right now with that platform. As for that 60k thing. Your ACR barrel will be considered shot out by most of us long before you hit 60k. The ACR is a military gun and acceptable accuracy for it is way different than for three gunners. Do you really think if there was a way to put a coating on a barrel and increase barrel life five fold we wouldn't have done it? This is the game where guys pay 400+ for barrels. Melonite isn't the holy grail of barrel life and it's been tried before.

I know the Miculek family showed up for the first year of the Crimson Trace match with what could best be described as a ghetto set up. Lots of duct tape. I think on the rifle and the shotgun.

Most of the guys are using vent rib barrels, but not the super high ones seen on trap/skeet guns. I don't think they would hold up to being tossed in dump barrels. The vent rib is nice. Doesn't heat up as much on high round count stages and for the guys still grabbing the gun up front for a loading technique you're less likely to burn yourself.

All kidding aside. Drilling into carbon fiber is not as easy as it sounds. Apparently there are some hazards that happen when you have tiny little bits of CF floating around. I've never done it but talking to people that do it for a living, it kind of a pain in the butt.

Duct tape.

Could be spots reserved for staff also.

They are allowed now. Just talked about it this weekend. The MG rule book covers any combo of two or three of the guns, or rifle/shotgun only matches. Just gotta have a club that wants to out them on. Go for it.

Does that mean if Robbie Johnson comes he can't use that Remington ACR he shoots? Experimental is not the same as new design. If you can think of an easier way to define "factory configuration" for new shooters who are trying to understand the rules, let me know. The truth is even my guns aren't in "factory configuration" anymore. We all seem to accept what it means, and we at RM3G couldn't think of another phrase to use to mean no phaser guns, or ice bullets or whatever. While the ACR may be brand new and "innovative" it's not truly experimental...And...although Remington is not selling them to the public yet, other people are...so...sure, it fits our definition! Sorry, just trying to help! And by the way, before you ask, buying separate parts and building your own gun is also available to the general public, they just may not be capable of doing so. Can you make your own barrel under our rules? Yep! The public can buy the blanks and the lathe... Like I said, we didn't like the phrase "factory configuration" but racked our brains for a better, succinct phrase and failed. We didn't want to spend a paragraph or page or an appendix to make a list of guns and/or parts to more clearly define it, as such a list would be out of date the minute it was written. So, we tried another phrase to do so.... The Remington version of the ACR is quite a bit different than the Bushmaster version. And completely unavailable to the general public (If it was I'd have one in my safe, cuz Robbie's gun is cool). I don't think there is a way to make that rule make sense. There are just too many variations to existing designs, new designs, oddball one offs, etc. I like your rule better than most. I just still don't like the concept behind it.

I'm also wondering what are the typical causes and signs of carrier tilt? I don't foresee an issue with that because of how much contact the carrier has with the rails and how tight fitting its is. But I'm not an expert and that's a guess so I'd like to know. Carrier tilt (this is my opinion only. Please don't crucify me like you guys have done to the poor OP) can happen in AR's equipped with a piston system. Basically the AR DI system was developed to have the force of gas centered in the BCG. When you retrofit that existing design to a piston system with the force coming at the top of the BCG instead of the center you can force the BCG to tilt or not ride precisely centered forward and back. Some designs have fixed this better than others. I've heard stories about holes worn clean through the side of upper receivers. I'm using the PWS system for work and they use an oversized BCG. Not much but enough that it doesn't tilt. Never had any problems with this one. I wouldn't think you'd have issues with carrier tilt in an ACR/SCAR system since they were designed from the ground up to be piston systems.

Does that mean if Robbie Johnson comes he can't use that Remington ACR he shoots?

I'll mention that to the officer who took a shot last weekend at 120 yards. He should have gotten closer like the officer did right before when he was shot. We've had a number of shootings at my agency. The average distance has been well past 25 yards for the last couple years. Most have been rifle shots. But we've had some long pistol engagements and even a successful stop at 100 yards with a 12 ga. One pellet of buckshot hit the suspect in the carotid and stopped him immediately. My idea of practical is staying as far away as possible and still dealing with the situation as safely as possible. 50 yards is not that far. As much respect as I have for Col. Cooper, going solely by his writings from several decades ago doesn't make anyone an expert.

I'd bet it's closer to 6. Haven't weighed it. Optic is an Aimpoint Micro, CTR stock and a Go Gun Super Comp. I'll try and weigh it when I get home. There isn't a lot of fat left to trim without going to a shorter barrel, or handguard. Or I suppose a Carbon Fiber barrel.

I really like my light rifle. It's not carbon fiber, but it's a 16" mid gas Bergara. Stuck it in a Seekins 15" upper and it points and holds very well. Did some off hand testing at 50 yards the other day and was getting more hits faster on a 10" plate than I did with my 18" match rifle. Not that hitting a 10" plate at 50 yards would come in handy for anything.

Maybe I'm missing it because it's so early but have you adjusted the gas block? Sounds like you've got it tuned for the hottest ammo you have and it won't run the weakest. I tune for the weakest I have.

As far as I know they have. 12 yard spinner with rifle? No way would I put that in the match. No way to control the angle of the spatter. But it's also pretty mobile on the axle. The steel does a pretty good job of moving with the impact. Try that with a static, or not as evenly balanced piece of steel and I'm betting you'd see some craters.

I'm pretty sure MGM is using AR500. Although even in steel grading there is a range. It's not exact. I've shot several matches with rifle steel at 50 yards. The MGM Ironman being one for sure. That's probably part of the restriction they have. I didn't realize there was such a velocity drop in the first hundred yards. I'm betting that 20" is clocking under 2800 by the time it hits the popper.

Again, it's not the kinetic energy that damages them. It's the velocity creating heat energy. That's why the craters look like they are melted. I've damaged steel at closer range using XM193. Shot the same steel with 77gr closer and didn't even dimple it. Not all steel is created equal. We use M193 exclusively at work. Our poppers are at 100yds and get shot by more rounds than any public range steel and there is no damage. Mostly just leaves a grey smudge. The poppers are AR500 steel. I believe the issue arises due to inferior steel or mistaken identity of the ammo. Not to keep arguing this, but are you guys using 16" or shorter barrels and have you shot it at 50 yards. There is enough of a velocity difference out of a 16" or less barrel compared to 18" and 20" barrels that are common at 3 Gun matches. There's also a bit of velocity loss by the time you get to 100. As an example, Winchester 55 gr starting off at 3240 is only going 2854 at 100. Figure at least 150 fps of that velocity loss is between 50 and 100. Hitting steel at 2800 fps and not damaging it is really not that difficult.

It's not how things will be. This is the first year the match has ever filled and we were trying something different. New shooters will probably still get in. Just like I said. It's just going to take a little while to get through the wait list. You'll probably still know for sure for 2014 sooner than last year because we didn't even open registration till Spring for this years match. This is a small match by nature of the shorter time we have to shoot each night. If you want to shoot, sign up this morning. I doubt you will be disappointed by the match. It's kind of fun.

It's not the caliber or weight that damage steel it's the velocity. A fast .223 will burn a crater in steel. .308 is generally slower and even though it weighs more won't damage steel. Watched someone smack a plate rack with .308 last year at about 15 yards. No mark on the plate.Hmm, usually its 308 shooters breaking stuff at our matches.I've only been checked with a magnet at majors They are probably knocking flash targets over or breaking welds maybe. But actual damage to the steel plate is unusual with .308. Unless you guys are using really cheap steel.
