What brand of sabots have you been shooting through your M4? I have been researching this a little on the interwebs and found this article. The sabot round they tested from a smoothbore keyholed at 50 yards. Sabot slugs are typically intended to be shot through a rifled barrel. If you found one that holds a tight group from your M4, I would like to try some. Mike

The M4 is a pussycat. At least compared to a pump. I don't even have a bruise from yesterday. I am shooting Federal Hydra-Shok 1 oz slugs (1,600 FPS). They are part number LEF127RS. I have shot the TruBall slugs before too. I think those might be more accurate. I tried an extended IC, flush IC, and flush cylinder chokes. I had the best groupings with the cylinder choke, but using that would definitely handicap me on the other parts of a 3-gun stage. I am searching for a good combination of slug and choke that will still allow me to knock over the steel knock-off plates with 7.5 shot at 10 yards. It has not been easy. Chokes tighter than IC definitely improve the plate knock down power, but as I understand it, they are not suitable for slugs. My grouping pretty much covered a 12x16 piece of paper at 100 yards. I had hits at the top, hits at the bottom, hits at the left edge, and hits at the right edge. I have done better than that in the past. I would like to keep them in a 10" circle at that distance. Maybe that is asking too much. Mike

OK, I run an optical sight on my M4. I typically use slugs to sight it in. Lately in my 3-gun competitions, they have been making us take shots at a steel plate (maybe 12x16) at 100 yards with slugs. So I would like to open a discussion about which slugs work best for everyone (most accurate) and which chokes they like to use. I shot about 30 slugs yesterday and I am still not happy with my grouping at 100 yards (if you can call it a group). Any advice or experience shared would be appreciated. Mike

Yes, I used the factory screws and washers. I just used 241, but I did degrease with rubbing alcohol and q-tips the best I could. Where did you find the factory spec on the torque? I looked in my manual but could not find it in there. Thanks for the reply. I will be writing that torque spec down in my notes. I might also tighten those screws up to 18 in-lbs. I have a torque screwdriver set. I think it is called a Torque-Vario or something like that. Mike

Instructions that came with the MI Aimpoint mount said to tighten the two screws that hold the mount to the receiver to 25 in-lbs. I was too squeamish to tighten them that much so I torqued them to 15 in-lbs with some blue Loctite. What are you guys torqueing the screws that go into the top of the receiver to? Mike

Dang. I am too slow. They are out of stock. Mike

I just ordered the trigger and disconnector from the FFT website. Just need a hammer now. Mike

I received the mount yesterday, but I only had time to look it over. It does only have two mounting screws that attach it to the M4 receiver. I plan to have it mounted by the weekend so I can take it out and sight it in over the weekend. I will let you know what I think. Mike

Put me on that list as well. Mike

I just got a tracking number for mine, so they are now shipping. Just thought the forum would like to know. Midwest Industries Aimpoint T1/T2 Mount for M4 Mike

It looks good. You did a good job on it. Mine needs 3 Dram or higher. I tried some 2-3/4 Dram (1-1/8 Oz at 1145 FPS) and I was using a single shot shotgun. This of course was during a competition. Mike

SD, did you do the relief work around the shell carrier opening? Mike

Are you living in the states? I am asking because I think this part is covered under ITAR. Mike

Great info! I am running some of the same things you guys are, but there is a lot of good info to digest here. I was running an RMR but ditched it for the Aimpoint after having issues in the rain. The rain drops got down in where the emitter was and all I could see were red splashes of light all over the screen. It was fine once it dried out, but shooting in the rain was problematic. I am definitely eyeing that MI mount and was considering ditching the SideArmor setup if I did. I am currently running two Carbon Arms Pinwheel setups on my belt, so I don't even use the sidesaddle. I am definitely going to look into the trigger components mentioned. I already have the Carrier Comp oversized bolt handle (why do you say "mythical?"), and GG&G bolt release. I ordered a Taran Tactical oversized safety and extended carrier, but they are on backorder. I really appreciate the feedback. It has given me some items to research and some good ideas for improving my setup. Thanks again and feel free to add more. Mike

I am curious about this too. I am looking for a shell catcher that snaps on and off without leaving anything permanently attached to the gun. Mike

I have a SideArmor on mine. With that setup, the shell carrier can be removed. I actually have an older style SideArmor setup for an M4 that I am not using. With the old style, the shell carrier is held on by two screws instead of it being quick release. Mike

I think I want one. It is not yet on the MI website yet. I currently run a 4 MOA T1 on a Larue Tactical quick release setup. There is no co-witnessing with my setup. Mike

I have been using my Benelli M4 to compete in local 3-Gun matches. It leaves a little to be desired. I am curious if anyone else is running one and what mods they have done to make it more competitive. I have an oversized bolt knob, oversize bolt release, and full-length titanium mag tube on mine. I am running a SideArmor rail and side-saddle with an 4 MOA Aimpoint Micro T1. I have ordered an AccuGuide Extended Carrier, Oversized Safety, and Nordic 2-shot extension, but have not yet received these. How about lightening the trigger some? It is a tad heavy for my taste. Any input or advice you might provide would be much appreciated. Thanks in advance. Mike
