I was unaware the M3 barrels came with chokes, I thought it was not threaded. Are you 100% sure it is an M3 barrel, or is my info faulty?

If he is competant, I would take the option you have discovered. I meant the latter.

You can buy another barrel and have it cut down for around $100 or so and re-threaded for chokes as well. Guy will also lengthen the forcing-cone, etc. You interested?

Sounds like an earlier model 11707 that got the 2-port barrel.

interchangeable chokes? I will guess 11707 as well. Take the stock off and see if it is a 2-position or 3-position tube.

How many gas-ports in the barrel? Pix of the weapon would be nice.

I am running a titanium tube and collapsible stock. The bolt-handle is all but unnoticeable. Just a technical number really. I have a buttstock shell-holder in black for the M4S90 if anyone wants it, It should arrive the 27th. I bought it before I knew I was getting the collapsible. I will post the model # when it comes in along with a price if there is any interest.

I see experiences like this. I see experiences like mine. Both come from competant people on both sides. I am forced to conclude that it is hit or miss with the Mesa/M4 combination.

Honestly? A 7-shot mag-tube and big pockets. Unless you want to carry those 3-gunner shot-shell holder things that clip to your belt. I don't want to make the M4 any fatter than it is, in fact, that is why I have shaved almost a pound of weight off of it over factory configuration. (or will have, when the parts arrive).

My experience was full of fail. Fit was horrid.

nah man...THIS is a REAL gunsmithing/manly tool!

Sucks. I was hoping to post a Youtube of my M4 slapping out 10 shots and making everyone wonder wtf!?

Alisske, Luckily I have NOT had to fire a shot in anger and hope I NEVER fire a shot in anger, no matter the situation. As I stated, many people have tested this ammo out to 25 yards and the patterning was horrid. At 25 yards I usually get a 18" pattern AT WORST from almost any OO I have shot. (With this stuff they were talking a lot worse than that). I find this to be "sub par". What you are saying is akin to saying that a LS6 powered Z06 'vette is "on par" with an Evo8 because they both went 0-60 in about the same amount of time. Nevermind that by the 1/4 mile they are about a second apart. See what I am saying? You didn't qualify the statement as in "for up close they work fine". As far as me "being out to get you" errr...no. Not out to get anyone. I accept your public apology, and apologize myself for the misunderstanding that has ensued. PS. I read this in the morning before ANYTHING ELSE had a chance to piss me off Ergo, your choice to leave the comments up that you posted so that I would indeed still read it, (instead of running a quick edit), while noted, was overlooked.

Good stuff! Might serve an application for very close (smaller homes/appartment like mine) when YOU NEED a bang every time, but I am still not a fan of the stuff based on what every test about it has shown.

This was based off of statements of another person who purchased the ammunition and posted a review about it. When it first hit the market at $1/round, it created a bit of a stir, and people wanted to know. Some enterprising soul went and bought a box (not me) and patterned it. Several people corraborated their test. I did not see fit to spend my money testing it.

Do you think it was the geometry of the shell, or lack of sufficient gas velocity to cycle the pistons/action? I figured the buckshot/birdshot wouldn't work based on the dram equivalent being around 2.5 IIRC, but I wondered about the slugs, except if it's a shell geometry issue, it obviously doesn't matter.

Then they better cart me off to jail, my M4's barrel is 18.5" . I belive 18" is the limit.

A small fee, a lot of cursing, and a replacement barrel would be my guess.

While I appreciate the beauty and craftsmanship, stuff like this just never seemed to do it for me. Beautiful work though!

Have you tried it? If so, which loads, and how far did it seem to lack in cycling? I have wondered about this one as well.

Don't speak with that smith again. That is a good starting point. Find one who will cut it/thread it correctly, etc. for you.

I did not answer your question because I didn't think I had to comment for you and everyone else to know the answer to it. I obviously do not have a 5.5mm wrench or it would have been already sent to the OP before he ordered one. As to the rest of your rant, I will just sit back and laugh, too funny.

I think this is the smallest real (not imaginary or intangible) item that drama has been created over thus far.

Please see the post 2 up. I did not do that job, although I wish I had the talent and with some practice I might could. From what I see, it's pretty easy.
