Here is a pic of the loading port and the dishing on the trigger plate. Straight from the hotel in Raton. I run a +6 Nordic extension and it only sticks past my 21" VR barrel by a few inches. I run a 21 only because that is where I cut it a few years ago. I have a +2 add on from The Shooters Source if I want to expand to a 12 shot tube. Ill post a full pic tomorrow. Kuan

Yes you can, but it is much easier if you open up the loading port. The receiver is of such a slim profile that the factory dimensions of the port leave a lot to be desired for 2's and quads. It also helps to relieve the front of the trigger plate where it forms the back of the loading port. A gentle dishing of that area helps with alignment. I will be running my 870 this week for the RM3G. I tried the Nova route but just couldn't get used to how it swings. I find that it is faster for me to use the load 2 / quad strong handed with this particular shotgun. Don't give up the regular 3 or 4 with the caddies, it still has its place. Kuan

Same here. With real iron sights as usual. Kuan

Don't screw the actual tube into the retaining nut too tight. Screw the tube down until it stops and then back it out 1/4 to 1/2 of a turn. This will allow for a little play and once you install the clamp it will align properly. That is how I was told to install the extension if you plan on using a clamp. Ken Anderson of Nordic Components gave me an education one day at the Pro Am. By backing off a little and allowing for some play, it doesn't apply excess pressure on your barrel and effect your POI. No feeding issues gave popped up and I have been running that way for 3 years.Kuan

I just checked the website for the triathlon and it shows to be on US 281 and further west. I am staying in Georgetown so we should not have a problem. Kuan

This match is only 2 weeks away. Any updates?

I tried a globe, but it was to restrictive and dark for me to make fast transitions. I use a standard type front post. The post is an Armalite NM. I would make sure that the changing out of front sight inserts does not fall under the rules about modifications to a rifle during a match. You would be removing a sight and replacing it with another and that seems akin to changing out magazine extensions on a shotgun in between stages. Kuan

Did someone say "bullet song"!!!!!!!! http://youtu.be/D0kSI7ZiTTA On a helpful note, I used to have a Remington PSS .223 with a 1-9 barrel and it shot 77 gr. Sierra's like a dream. My shooting buddy has a 700 LTR that is 1-9 and it runs 77's and 75's with no problems. He keeps talking of pulling the OEM barrel in favor of a faster twist so he can shoot 80gr + VLD's, but it shoots the 77's so well he can't justify the cost. Kuan

The published velocity for that load is 2850 fps.. The previous posters are correct that it does have higher pressure than Hornady's semi-auto specific load. Hornady produces a 155 OTM load with a published velocity of 2775 fps. and I have found that it does shoot softer. The semi load also features a bullet that has a cannelure and the primer is staked so it won't back out of the case. Your AR pattern 308 should have no problem with the factory AMAX load. Just watch for signs of excess pressure. I currently shoot the 155 OTM load for all the HM matches, but my supply is running low and I will have to switch to something else. I would like to load the Sierra 135 gr, but finding some more H4895 has been difficult lately. A factory 135 would be impossible to keep in stock if the big names would add it to their lineup. The MK 319 SOST round looks promising, but at $1.26 a shot it is a little cost prohibitive for me right now. Kuan

Welcome to BE. The AR 308's will always be slower than the .223's due to the increased mass of the moving parts and the distance that they have to move. They will push you around more when you shoot them regardless of their mechanical setup. I can't really give you a time estimation for the difference between the two as I really don't pay any attention to those numbers. Don't worry about it being too unmanageable, proper technique will go a long way. CO-exprs is dead on when he speaks of learning to manage the rifle. For example, my AR pattern 308 is pretty much a standard gun internally. Armalite AR-10 pattern with a 16" barrel. Factory full mass BCG, factory buffer and spring, and Armalite 2 stage trigger. The only change mechanically to the rifle is a Surefire muzzle brake. It runs as reliably as any gun that I have ever shot, but it does move around more than the highly tuned ones available from JP Enterprises and Triangle Shooting Sports. I mention those two shops because the JP LRP-07 is the softest shooting AR 308 I have ever fired, but they come at a price. If you don't want the full JP rig, then contact Triangle Shooting Sports and talk to them about things that they will do to you gun. I have seen Benny's work on the big guns and his Rolling Thunder brake is one of the best on the market. One of Benny's guns would be great for a 3-gun and general purpose rifle like you mentioned when fitted with the suppressor adapter of your choice. General words of advice for AR 308 setup; keep it lightweight (around 8.5 lbs empty is a good mark), reliable (don't get crazy with a bunch of bells and whistles), and get good with the trigger. Long range follow up shot capability becomes less important when you hit the target with the first one . If you settle on the 308, let me be the first one to welcome you to the Torque and Recoil Club. We are a small but fun group. Kuan

I don't know about that. I do not have the barrel in hand, but it is the one that I am going to use. I have one on my TO gun and it has been an outstanding performer. Kuan

Don't worry about the .650 diameter behind the gas block on the JP barrel. There is a raised shoulder at the back of the .750 gas block surface for your piston guide to mate up to. I am doing a barrel swap on my ACR with a Nordic Components stainless 16". Results to follow. Kuan

When your skill level increases you have fewer misses during a stage of fire. Less misses = fewer shots = less heat buildup. This applies to most 3 gun stages as they won't have a huge array of rifle targets. I cannot speak for rifle only matches, but I could see a benefit from one in a 1 gun match like that. Kuan

Reference to the carrier tilt question. I don't think that you will see any issues. Carriers have been riding on rails in carbines for more than 60 years. The piston AR problem was caused because there was no bearing surface on the rear of the carrier to combat the tilt when rearward pressure was applied above the long axis of the carrier. The DI system applied force down the center. I looked over quite a few early piston guns that had broken the real takedown pin lug clean off of the upper due to carrier tilt. The large diameter tail on current piston carriers seems to have alleviated the issue. Kuan

I have an ACR and have had the opportunity to shoot quite a few rounds through it. I think that it is a fun gun to play with and I will probably run it in a local match for grins, but it won't be traveling with me to any majors. It does exhibit less muzzle rise than the majority of 16" AR's, but a lot of that is because of its weight. I have the enhanced version and with its railed aluminum fore end it weighs in 20-30% more than your typical AR. Recoil is soft, but the muzzle moves in a circular manner reminiscent of an HK G - series battle rifle. I have had a lot of time on MP5's and HK 53's and a fair amount of time on an HK 91, and it feels a lot like the 53. I have not outfitted it with a muzzle brake because it is a play around gun, and I don't want to drive my shooting buddies to the other side of the range from the beating. I have shot it in comparison to a buddies SCAR 16s, and the SCAR is lighter and moves a less with the PWS brake that the comes on it. We did not pull the brake off for a true comparison. Ergonomics are pretty good, but I would like to have an option for the pistol grip. What you get is what you get, a Magpul profile grip. Hopefully the alternative lowers that the OP referred to will remedy that. Accuracy is on par with other piston guns that I have. It runs about 1.5 moa with good ammo, and 2 - 2.5 with XM193. I have thought about doing a barrel swap with a Nordic barrel that I have just to say that I did, but 1.5 is enough. I would like to get hold of a lightened carrier if the became a production item and they don't cost an arm and a leg. At that point there will have to be additional gas plugs to reduce the pressure so the system doesn't run at warp speed and beat itself to death. It would take substantial work to make it a high level competitor in the gaming rifle field, but there are possibilities. Kuan

As Lead-Head mentioned earlier, you will be at a disadvantage with that flip up rear because there is no quick elevation adjustment for long range shots. Also you will run into windage issues because of the multiple moving parts. The Magpul series has so much side to side movement that it can result in over 6 inches of change in point of impact at 100 yds. This usually only applies to the first shot as recoil will cause the sight to settle into a consistent position. A good run on a stage can hang on a single shot, so taking on additional variables is counter productive. A cheaper route to having a good rear sight is to find a detachable carry handle for cheap. A few minutes with a hacksaw and a file will give you a stand alone rear. This is what I ran for a number of years before I acquired the LMT. Kuan

I run an LMT stand A2 style rear with a standard rear aperature. I stay away from "match" rear apertures as they are too small and can make things tough when the speeds go up and the daylight goes down. You can use whatever you desire as long as it is rugged enough and simple to manipulate. I stick with A2 style because it has an easy to use elevation knob if I feel the need to dial for that last long range target. A majority of the other iron shooters that I know use the same type of setup, except for Mike Payne and his dual Matech rig. He peruses these posts frequently and would probably chime in. Its pretty nifty set and he runs it very well. Kuan

I won a box of 500 off of a prize table a little while back. I finally got around to loading them up and they shoot very well. 24.5 g of H335 has them at 2940-50 out a a Nordic 16" barrel and they are right at 1.25 moa. I have not shot them past 200 yet. Kuan

The cone creates backpressure, much like a suppressor and some types of muzzle breaks. The best thing to do is shoot it with and without the cone installed. You will notice a difference between the two, and it won't be due to the weight difference. Kuan

I might be coaxed back to the rock for an irons only match. Kuan

Although BATFE classifies it as a flash suppressor, the design includes a cone-shaped removable baffle. There is a reduction in rifle and muzzle movement when the baffle is installed. Since it does "compensate", I think it would fall under that term. It is way outside of the dimensions set forth for compensators in most sets of rules.

Purpose built platform that mounts to any class 3 receiver hitch. Shooter is seat belted so they can't fall off. http://www.youtube.com/watch?v=EZCN1Riw87o 2x4 uprights are used to limit the shooter for 180 purposes. Vehicle speed was 8 mph.

Reminder for North Texas shooters about the Fall 3-Gun match at Tac Pro Shooting Center on Saturday September 28. There will be 5 stages total with 4 of them set in natural terrain and one shoot house type bay. Tac optics type rules except for an 8 rd maximum capacity on the shotgun (you don't have to plug it, but don't put more than 8 in it at any time). Iron sight rifle shooters are scored separate from the optics shooters on rifle stages. Scores are combined for finals. Slings are not necessary, but bring one if you want. You might find one to be handy for one of the stages. 　 Approximate round count: Rifle 50 No steel core or AP Pistol 50 Shotgun 35 birdshot, 2 slug NO BUCKSHOT The round count is low if you hit everything that you shoot at, but bring at least twice as much to be safe. You will be breaching a door with your shotgun and shooting from a moving vehicle in natural terrain. This match continues to be new shooter friendly. If you want to give 3-gun a try but don't think you have the right gear, don't worry and bring what you have. With this match you can have a great time with your common .223 carbine, 5 shot pump shotgun, and a single stack pistol. Golf cars / ATV's are welcome, but you can drive to the stages in your daily driver. There is a prize table at the end of the match that is awarded by RANDOM DRAWING. Even if you had a bad day, you might walk away with some pretty good stuff. I am not a match staffer and don't know what will be on it, but at the last two matches Kel Tec has provided a KSG shotgun. For more info go to www.tacproshootingcenter.com and look for the entry form. With such short notice it is better to register by calling them at (254) 968-3112. Be advised, I had a fair hand in designing and setting up the stages. You will be challenged! Kuan

I don't know if there is a match hotel, but there is a new Holiday Inn Express in Weatherford and its only about 20 minutes from the range. Plenty of choices in places to eat also. There is also a Best Western in Cresson that is only a few minutes from the range. Kuan

Maybe one of the Samson boys can help with that. I saw a very slick set on the forend of Andrew D's. Kuan
