LMOS and light buffer. Retune the fas block and spring for reliable function and you will be about as far as you can go. Also... There is a great deal of muzzle movement you can overcome with technique. I'm curious to know if NY has defined specifically what a comp is. Does a legal description exist? The reason I ask is because you might be able to have compensator features machined into the barrel itself.
Which is MagnaPorting, and like Doug said, is Open Division.
So, if the rifling is back bored and the compensator slots are machined into the free area, that would be open gun? Also... If the guy is in NY, would the local match director care? That's a whole other state, playing by a whole other set of rules. They might need to adapt to the conditions to have anything really fun to do.

I run one in my 308. Makes the rifle lock very smooth and quiet. 16k rounds on the original spring too.

Benelli Vinci is the same. I've not bumped it by accident, but I do use it to unload the magazine.
-
I also prefer load 2 and I still do an old fashioned caddy load when the situation calls for it. I'll take a good ole reliable 5sec reload all day, every day.

Did you try Barry White music and long slow dances?

Out of the right barrel (and the rest put together right) it will do sub-MOA, at least with good supersonic loads - within reasonable distances for its velocitySince 300aac is not really a precision round...
You are right. With the right build, the right loads, with glass and in the right hands, sub MOA can be achieved. But from a round designed for suppressed SBR's who cares? If you really wanted a rifle for precision shooting at distance, 300aac is the wrong choice. For what the round was designed for, 2moa is plenty accurate. The barrel twist in most 300 barrels is wrong for the fast stuff, you might want to reach out with and the subsonics have such a wicked arc, they are the way wrong choice for targets any further than 150-200yds.

Since 300aac is not really a precision round, the tumbler will take off enough for what you are doing. The edge will round off enough to not scratch up the ogive while seating. I only trim and debur my long range stuff for that extra half MOA.

Now the gun I have never gotten to handle and have always been curious about is the Benelli M3.

Nova isn't perfect, but still the best choice out there. Believe me... When a better pump comes along I'll be all over it. P350 throws live shells out the ejection port and SXP can't be opened up for load two or quads. M500's and 870's just simply aren't reliable enough. I'm waiting to see what Pat has to say about the P3000. Only pump I enjoy shooting more than my SN is the Browning BPS. Not worth spending $700 to see if it will work for 3gun.
As to the complaints... The safety is only an issue because people like to gripe about it. Never slowed me down. The short stroke a practice thing. You will short stroke a 3" gun too. The polymer reciever has steel plates imbedded. They can be squeezed back down... but I have about 18k through my SN (both light target and heavy hunting loads) and not experienced the receiver flex issue.
Certainly room for improvement, but it gets the job done pretty well. I can help you set yours up to minimize the negatives.

If you grease the slides and barrel feet and use a very high quality oil on the barrel and locking lugs, you should see about 100k before accuracy starts to noticably drop off. The barrel is what starts to go, so a well fit replacement should get it right back in the game.

Pick the one that gives you a chubby and hit the range.

Damn the fog and rain... Best HeMan Nats yet! Thank you JJ and Denise for all of your hard work! The stages were awesome, and the challenges aplenty. Nothing better than a weekend at the Whittington Center with good friends.

Dear Shotgun Challenge Entrants,
When we set the date for this year’s Shotgun Challenge we chose a date which appeared to be open in the national schedule. Since that time, several other major matches scheduled events for the same weekend. With so many excellent events to choose from (that’s a good thing) that people don’t want to miss out on, our humble event has a thin roster. Thin enough that the match simply is not financially feasible. After a long discussion with our title sponsor, it is with our deepest regret and disappointment that we must cancel this year’s shotgun challenge.
When we started this match it was with the intention of improving the exposure of competitive shooting sports near our fair town. Since that time two already, very successful 3 gun matches have sprung up within an hour of Colorado Springs. Attendance at the local UPSA, IDPA and Steel challenge matches are way up and the SoCo match sells out every month. So we consider the match to be a big success. We just chose a bad weekend this year.
All paid entries have already been refunded. Please let me know if you experience any difficulties. I sincerely apologize. Next time we will try to pick a better date.
Michael Payne

True on the powder selection, but now you are using powder burn rate to manage operating pressure. Slower powders such as Varget are not optimum for shorter barrels. So now you are giving up velocity to gain operating pressure just for the sake of running a rifle length 16" barrel. Why? By running a mid speed powder like H4895, you get a more complimentary burn rate in your short barrel semi auto and a mid or intermediate length gas system is a better match for the pressure curve and the additional dwell makes it more forgiving over a wider range of loads.
-
Mine is the same experience. I've run rifle length 18 and mid length 18. Both felt over gassed to me and needed an adjustable gas block to fine tune the performance. I have to agree with JP. 308's experience more variance in pressure and gas volume than 223. Once the 18" mid gas block was set, it worked great with most anything I fed it. The 18" with rifle length gas has less dwell, making it a little more finicky. Not a lot more, a little more. This would manifest as some an occasional failure, if I set it up right on the edge, using my 155gr load (410pf), and then ran my softer 125gr ammo (375pf), or some nato ammo (365ish pf).
If your goal is to run without an adjustable gas block, then an 18" rifle length gas will likely serve you well. If your goal is to have the softest, smoothest 308 action, then adjustable gas is important and the gas length won't matter as much.

Take a look at your guide rod. If you are running the LB GI guide rod, they are a high wear item and might not be moving smothely with the movement of the barrel. Next, look at the interface between the end of the barrel and the bushing. Make sure the bushing isn't wearing into the barrel right at the slight flare near the muzzle. Lastly, check the barrel lugs for excessive wear. By 50k rounds the Kart barrel in my Baer was worn out. Not the rifling, but the outside contact and wear points. My bushing had worn down the top of the barrel, causing a small hickup there at the end of the travel, slowing down the slide. The lugs had worn down so that it would no longer push up high enough to lock up into the slide. I had a new Barsto barrel fitted up by my gunsmith which has given me 100k trouble free rounds.

The lower doesn't have a number. So the barrel is the gun. Barrel swap means a whole new gun.

The trigger guard on the super vinci was reshaped to eliminate the pinch, but it's plastic and can be easily reshaped yourself. SN on the barrel keeps you from being able to swap out barrels. Overall I really like the Vinci's also. When I show mine off, it gets mad compliments on how it shoots, but they don't sell as well as they should because they are non traditional looking. Now if the Ethos could could be addapted to 3gun... That would be sick.
-
Cut off 2 coils and the pistol will shoot nicer and the spring will last longer. I change mine once a year (10-15k).

I really like the Vinci line up. All shotguns have an issue or two to deal with, but the Vinci gets really close to ideal. Port work is easy. You don't need to change the lifter. The recoil is very mild. The ergonomics are excellent. There are only three major complaints... The safety is in front of the trigger, the back of fhe trigger guard needs to be reshaped to avoid pinching your finger and the SN is stamped into the barrel. While I love both my M2 and Vinci, to be fare... my M2 did take more work to get it ready for 3gun.

I have both single stacks and 2011's in 45. All run excellent and feel great in the hands. The 2011 is a little more ergonomic and fits larger hands better. Also the 2011 is fasrer to reload, especially on the move. And... 16 rounds of 45 is super fun. Down side is that the mags are considerably more expensive and have to be tuned by some one who knows what they are doing. 2011's in 45 are a little finicky, but once the mags are tuned right they are good to go. When I compete, I always grab the single stacks though. The mags are cheap and I can fit more of them on my belt. I have always liked the feel of my steel frame single stacks over the polymer frames of my 2011's. So... Pick your poison, commit and get good with whichever you decide to go with.

The 1x Prism scopes are 1x, the adjustment on the back is a diopter to adjust one eye to the other, same as binos, for two eyes open shooting.

Totally different target crowd. The hydrolic buffer (i had one) is heavy and serves to reduce rearward felt recoil. It is only usefull in over gassed guns and does nothing to improve lock up or quiet the spring.
