The barrel ring pushes back against the forend when the magazine cap is tightened so the forend will be tight against the receiver. The lugs in both versions are the same width so there won't be any play in that direction either.

Yeah, I mis-remembered why I had to do a little fitting to put it on the second gun. I was thinking it was a newer gun but it was an older one as well but the configuration at the point where the tube meets the receiver was a little different causing the aluminum sleeve of the surefire light to wobble around a bit. Forget that part above about the surefire. Suffice it to say, the older guns have the slightly smaller diameter portion of the tube that the forend fits over. Here's a pic of three different versions of the receivers/tubes. The top is the oldest (probably the same one you have with the full length magazine tube-7 rounds), and the bottom is the newest. The widest part (diameter) of the top two tubes are 1.085". The widest part of the bottom tube is 1.095". A newer forend will not fit your older gun without some sort of spacer to take up that slack. Sorry for the confusion above. I'll edit the Surefire reference out. You can see what I was talking about in the difference between the top tube and the middle tube. They're the same diameter, just a slightly different configuration.

There are at least 3 forend versions for the M1 that I am aware of. Two versions have a longer cutout for the barrel ring lug. Earliest version barrels have a short lug relative to the later versions. The cut-out in the forend is different to accomodate the different length lug. Different lugs: Short early version on top- Also, the earliest versions are made to fit a narrower magazine tube at the point where the tube meets the receiver. The magazine is approximately .010" wider at that point on newer guns so if you tried to put a newer forend on your older gun, it would wobble around at the rear. The difference in the cut-out for the newer longer lug shouldn't matter with the older shorter lugged barrel. All mine have two washers; 1 flat and one "bent".

Yep, if you're used to looking down the top of the receiver to a bead front sight, you're going to have to make a slight adjustment in using the ghost ring sights since they're elevated above the receiver and barrel a lot more than a regular bead or vent rib shotgun. I shoot M1's with both and with the ghost rings I only have to rotate my head up just slightly. I still have a good cheek-weld.

Don't need?? How about: Upstairs gun, downstairs gun; House gun, car gun; My gun, wife'/son's/daughter's gun; Primary gun, backup gun; One model, another model; and so on. Or, how about: Want guns, have guns. Yes, I have a bunch of posts today. It's raining cats and dogs down here. Otherwise, I'd be shooting skeet right now.

Not any more but it did when I bought the bag and it fits just fine. Total length on this gun is 35.5 inches.

I use one of these for my M1, 14" Entry Gun. http://www.eagleindustries.com/product.php?productid=390&cat=65&page=1

We've used Rocky Ridge Retreat in Gregory for a number of years. I don't know what your price range is but RRR is comparatively reasonable. They don't update their website much but their contact info is there. We've always had good hunts with them. http://www.rockyridgeretreat.com/index.htm

Well, Nordic made me eat my words. They have a prototype in the works. How 'bout that?

If you removed the forearm washers from the front of the forearm, make sure they are reinstalled in the forearm behind the barrel's guide ring, not between the front of the guide ring and back of the magazine cap portion of the extension. There should be two flat washers on either side of another washer that looks bent. Holding them in place are a clip-type washer that fits into grooves in the forearm.The only other thing I've seen on aftermarket extensions is the threads on the cap not being deep enough to fully seat the extension on the barrel ring. But, that also allows the barrel to move as well as the forearm. If the barrel is tight, the only other thing that would make the difference is that forearm washer/washers being in the wrong place or missing altogether.

When he says "it came with" the carrier comp extended tube, I guess he means tube wasn't installed on the gun. He now wants to install it which would necessitate removing the factory tube. I wondered about that myself. The original post was a little ambiguous.

Loosen the magazine cap, slide the forend/barrel forward just a bit. Put the "bent" end of the bolt release just behind the forend so the long end is hovering over the factory bolt release. Pull the forend/barrel back, trapping the bent end of the bolt release behind the back of the forend and tighten the mag cap. That should do it, if I recall correctly. I had one years ago but changed it out in favor of the GGG release.

If you check the previous thread highlighted in the post just above, you will find that I have been using a M2 barrel on one of my M1 receivers for about two years now. Originally, I slightly modified the M1 forend (see the pictures) to fit the M2 barrel. Since then, I put a M2 forend on it so now I have a hybrid M1/M2. Thousands of skeet rounds have gone downrange (some of them even hit the birds) with absolutely no problems. Even with the slight differences in the barrels (as noted in the pictures) the combination works just fine. No modification to the barrel itself is necessary.

Help you how?

No 20 ga. for sale here. No, you can't put a 20 ga. barrel on a 12 ga. SBE. There is no such. SBE's only come in 12. If you're asking about putting a 20 ga. M2 barrel on a 12 ga. M2 receiver, the answer is still no. Or, a 20 ga. M2 barrel on a SBE receiver. Double no. Have you checked GunBroker? There's usually several 20 ga. M2's listed there.

Here's a picatinny rail mount for the contour. http://strikemark.com/news/new-design-contour-camera-picatinny-gun-rail-mount/ Now all you need is a barrel clamp with a rail. This is obviously designed for the mag tube but it might work on the barrel. http://www.mountsplus.com/AR-15_Accessories/AR-15_Scope_Rings/130-CMD-MT-3.html If you have an extended magazine, you could use one of these. http://www.cdmgear.com/winbmt.jpg

Have you tried Benelli? I would check with them to see if recoil spring/tubes are still available. They could also tell you if one of the current model tubes will fit.

Due to the configuration of the gun, I doubt that you'll ever see that.

I would try a variety of slugs and see what works best unless you're talking about an agency gun, limited in what you can use. There's really no general "standard of accuracy" for a slug out of a specified-length shotgun barrel. If you're limited to Federal Tactical Slugs, then their accuracy out of your gun is what you get, period.

Quail are extremely habitat sensitive. Best practices management can be expensive. Land that had lots of quail years ago but not maintained "properly" for quail will see a reduction in numbers over time. http://www.talltimbers.org/gamebird.html

With Brenneke KO slugs my 14" M1 S90 will shoot three inch groups @ 50 yards.

There's a reason they make different interchangable chokes. It depends on what kind of shooting you're going to be doing. You said what you're NOT going to be shooting. What ARE you going to be shooting? Competition; other games; other game; home defense?? Several chokes can handle both slugs and buckshot. Some say Improved Cylinder is best all 'round, others say modified, others say something else. I say get 3 or 4 and change as needed, depending on the situation. And don't forget to pattern the gun. Shoot different loads out of different chokes to see what works best for the differing situations. If I had to pick one shotgun, one choke, one slug and one buckshot, I'd grab my M1, improved cylinder, Brenneke KO slug, Federal LE13200 low recoil OO buck. I can still shoot birdshot for skeet & small game. But since I don't have to limit myself that way, I change chokes when necessary.

They can be had for 7 - 8 hundred bucks but with the 21" barrel being the choice of the 3-gun crowd, some are starting to go for more than that since 21" barrels by themselves are rare and expensive commodities. As for the 21" barrel being less than ideal, I'll respectfully disagree. I have them on 2 of my M1's which are used for skeet, trap, sporting clays, 5-stand, and SD pheasants. I love them. If you buy the gun and want a longer barrel, I have a 26" that I'll gladly trade with you. M2/SBE2 pistol grip stock will not work on M1. If you're set on a pistol grip stock, I'll trade you one of those for the field stock as well.

What they said. I use my M1, 21" for skeet, trap, sporting clays, 3-gun and pheasants. M2 much the same gun. Very versatile.
