Cut the little "nub" on the end off, and use a high-strength out-door rated double sided tape to attach it to the receiver.


The Mesa tactical side saddle carrier I got, ended up DESTROYING the receiver threads in my M4s90 shotgun. The screws they use(d) were made of very soft carbon steel, and would stretch and deform under recoil. Then you would tighten them up, and slowly rip apart the Aluminum threads in the receiver. This was an epidemic at AR15.com, about 10-20 people reported having the same issue.

I DID use a torque wrench to tighten them to the specified torque too - about 18-19 inch pounds - and it still destroyed them over a few shooting trips.

The sticky-tape method I have been using for the past 2 years works BETTER than the mesa tactical "over top" method (lighter, stronger, wont permanently damage your gun).

I can literally grab ahold of it with 8 fingers in the 8 shell loops, and shake the gun AS HARD AS I CAN and it wont come off. I have done this several times ;) . If you did this with the mesa unit stock, it would rip out the threads.



I got the tape at Canadian Tire, in the tape/epoxy section. It was a dark/medium grey color (red packaging and a red-peel away film) and was "out-door" rated and weather proof.



Tactical Shotgunner is a GREAT place to buy from, Ron is a good guy and will do whatever he can to keep exporting stuff :D
 
If the inertia of the shells is the problem and it is causing stress on the top mount screws, why not install the correct one and use the super tape to eliminate the screw stress. It will make a better looking package without any problems.

Actually, If I may say so, I think it looks quite a bit better without the big arm coming over the side. Not to mention that it doesn't raise the picatinny rail up and interfere with your iron sights. Not a big problem if you're running a red-dot like me, but I do use irons a lot as well (the M4 has awesome sights :D )

The rail on top was designed to take optics, not a shell carrier. It was never meant to take the extra weight (with the carrier plus 8 shells, that's gotta be what, 1.5-2 pounds extra? )

I DID try to put the double sided tape in between the carrier and the receiver then bolt it on, however the tape was a bit too thick, I couldn't get it to line up properly. However like I said, strength is no issue. I can use the shell carrier like a carry handle and shake it as HARD as I physically can, and it wont budge at all! :D



Now keep in mind, when I did mine, I had the entire top "arm" to cut off, with the 870 one I posted earlier, its just the little nub at the back, and you wont have to mess around with painting or coloring it. (I used a sharpy because I didn't want to mask everything off and paint it :p )

I wouldn't be advertising this way unless there were problems. Like I said before, at AR15 there was a huge thread about people having problems with them, including one guy that had the carrier fly off during a shooting match!


Even IF this way fails and the carrier comes off, you can just clean it up and tape it back on, no problem. But I have had mine like this for over 2 years now and done PLENTY of shooting and hunting trips with it, and it works like a charm! :D
 
Casey - have you heard of this issue before? It's a new one to me! I just bought/mounted my Mesa rail/saddle combo, and never in a million years would have thought anything other than 'bulletproof'!!!

If you got a new one you might be okay.


The one I had, had the "first gen" screws. they were VERY soft, to the point where the Aluminum would deform the threads, and then once the threads were deformed, it would rip the aluminum threading to shreds in the receiver.

Even though it would seem to make sense to use a "soft" screw to not damage the Aluminum, any deformation at all will put the pressure on one or two "threads" and slowly deform them, then the next thread, then the next etc...

The newer ones are SUPPOSED to be "hardened" screws though. The threads on my receiver were about 50% destroyed, its a good thing the factory rail screws are almost 100% threads, I was able to get enough for it to grab. I ended up having to epoxy the rail and screws on, so they wouldn't pull out.


Mesa Tactical really dropped the ball on the original screws by using cheap chinese made screws. In fact MOST of the attachment hardware for their sureshell carriers have some sort of problems.

The 870 "pin" screws can clamp the receiver too hard and cause binding. The new ones prevent binding, but the heads have been reported to "pop" off sometimes now.

Mesa makes AWESOME stuff, but the screws and hardware they use is by far from "good" quality stuff, unfortunately, its kind of poisoned their reputation.

I have never heard of it before but I believe what is written above and that it could happen on that particular gun.
 
The best way to check the screws is to see how magnetic they are.

IF they are "Hardened" carbon steel, or stainless steel, they should be barely magnetic at all. (they shouldn't even stick to a fridge magnet, or it should just barely feel attracted to a magnet)

If they are soft carbon steel (like the faulty cheap screws Mesa used to ship them with) they will be quite magnetic, and will stick to a fridge magnet.

I actually found some M4x0.7mm Metric flathead screws at Canadian tire, I had to cut em down a bit from 12mm OAL to 10mm OAL. It didn't end up making any difference for me since the threads were already toast at that point, but if you get some good screws it SHOULD stop the problem from happening in the first place.

As already stated though, use some good blue loc-tite, and DO NOT over tighten them past 20 inch pounds.
 
Well, I blue loctited, and tightened to 16 inch-pounds, as per instructions. I have a Utica torque driver, so that should be pretty accurate!

Now I'm gonna test the magnet trick.. ;) thanks!
 
I checked mine out, took 1 screw out and it's quite magnetic. Sticks to a fridge magnet easily.
However, all 5 screws are tight and I only have the 6 shot carrier attached. Also, if this issue is caused by firing the gun when the shell holder is full, I shouldn't have a problem. The shells on the carrier go into the gun, so there's none on it as it fits 5 in the tube and 1 in the chamber. :)

Not meaning to hijack your thread, but since were on the M4 topic......... What's the deal with the position on the telescoping stock that locks the butt pad at about a 45' angle? Thug/gangster setting? :confused:

It's near the middle setting.

Its for piecing the pie and looking around corners/door frames.

When you put it at the angle, you can get so close to the corner of the door, that your head just barely pokes out. Now try it with the stock in the normal position and a lot of your head and shoulder is sticking out too.

You can do it pretty well with the stock "upside down" for lefty-shooting too.

You cant use iron sights in that config, but indoors stuff is so close range its not a big deal.

Gotcha :redface:

Everything I've read mentions 3 position. I thought maybe I had some super-cool, Special Forces add-on. Not much into tactical stuff......evidently.

My wife is now 100% certain I'm a nutjob after peeking around doors with the new toy for the past few minutes after reading your post. :D

Its actually pretty cool :D

Now try to get used to adjusting the stock on the fly ;)

I had to try it . . . my wife is also worried.

I just muttered, "Checking for those goddamned Zombies. Go back to bed!"
