You may want to reconsider using the Larue mount if you're using the factory pic rail since it's been documented to damage Larue QD mounts. If you decide to change course, ADM makes a dandy quick release for your optic.

Please don't take any offense to this, but DON'T DO IT! As much as you have stressed about your gun so far, you're really gonna be upset if you strip one of the receiver screws. There was s time that Mesa Tactical shipped this product with the wrong pitch screws and it caused a lot of heartache when folks ruined the factory threads. Even if they've solved the screw problem you still have to factor in all the additional weight and stress that the shells put on the receiver holes. Do yourself a favor. Watch a few slow motion videos to see just how much energy the rail receives during recoil, and do a Google search. You are bound to come across enough information to make you think about pursuing this accessory. Once again, please don't take offense. I just don't want you to have anymore stress with your gun and simply be able to enjoy it.

Beautiful shotgun my man! Thanks for sharing!

I personally prefer to mount an RMR on a ADM quick release low mount, attached to the factory picatinny rail. The height is perfect for the middle position of the C stock and isn't cluttered by the iron sights. If something goes wrong with it you can pop it off with a quick flip of the lever, slide the stock back to the last position, and have perfect sight picture with your iron sights.

Likely means it's blue. HAHAHAHAHA! Sorry man, I couldn't resist.

Press and hold the bolt release latch in, tilt the trigger guard down, and slid it out the back. Once you get it out remove the bolt before trying to reinstall the trigger guard. Make sure you depress the bolt release and hold it when reinstalling the trigger. Also, make sure the hammer is cocked before replacing the bolt.

If you can't pull the bolt back at all, then no, it isn't normal. If you can pull it back a little but not far enough to cock the hammer, then yes, it's a known phenomenon with the M4. By the way, congrats on the new gun!

Before doing anything I'd encourage you to mess around with it a bit more with the pistol grip snug. Try making TINY little changes left or right with the grip because the trigger group is notoriously finicky about going back into placed unless the pistol grip is lined up perfectly.

Very timely post since I am looking to have an extra trigger group to send to Briley, while I have my mostly stock one here so I can still use the gun during the 5 wks down time. That is unless SD might have a complete 922R compliant polymer trigger pack lying around that he wants to sell (hint hint).

The two I have here look pretty much the same. I got my son in law to look at the one I loaned him and he says it's the same too. Considering the only thing holding it in is the friction of the O ring, I'd rather have more contact than less. Regardless, it's a cheap, consumable part, that you'll rarely remove unless you do a detailed strip more than is necessary. Enjoy that new gun and going broke buying the parts to modify it to your personal preference ?.

Another vote for the RMR. Optic and mount comes in right at 3 ounces which helps ease my fears of a heavier optic causing excessive strain on the rail mounting screws under recoil.

I wouldn't want to be the one to field test that particular prototype. The extension takes a considerable amount of force during recoil. The stout recoil you feel is transferred down that extension and through the stock. In addition, the spring and cup inside of it are constantly rubbing away on the inside during each firing cycle. If it fails the results could be rather painful.

Check the bottom corner of the barrel extension for a burr or rough machining. The good news is your receiver will get more wear marks that correspond with the barrel extension as you shoot it so the scratch won't stand out as being abnormal or accidental in nature. Eventually it will simply blend in with the honest wear and tear.

The screw heads are located on the inside of the receiver. Remove the trigger assembly and you'll see them. Be aware that when I removed the rear sight on my first M4 back in 2016 the screws appeared to be somewhat swaged. If that's still the case you'll likely need new screws if you want to reinstall it at a later date.

Keep searching and don't give up my man. I placed wanted ads online, did extensive Google searches, posted wanted flyers at the gun club, and inquired of vendors even if they were listed as out stock, in the hopes it paid it. It finally did and I found one last week for a very fair price, right in my own backyard. Don't get discouraged or give up because they are out there just waiting on you to find them ?. Good luck with your search!

Thanks for the offer! I imagine it'll likely make its way to you sometime this summer so you can work your magic. Oddly, as mentioned in my first post, the gun actually fits me better and comes to point more naturally than my other M4 with the collapsible stock. If I had to explain it I'd have to say it reminds me of my clays guns where the comb is cast off, as well as the toe, allowing my cheek to fall into place quicker and centers the heel of the stock directly in the sweet spot. If I could get over my OCD, in all honesty I would probably keep it this way ?. Edited to clarify, In my previous post I mentioned I purchased my LE model at the beginning of the year. I Keep forgetting we are in a new year, so that should have been stated as the beginning of last year.

Thanks for the input guys! The stock lockup is quite tight in all three positions, and is right on par with my other M4 (LE model) that wears a collapsible stock, which was purchased at the beginning of this year. I could be completely wrong, but it seems to me that the increase in production to meet the demand has created a situation where quality control isn't as thorough as it had been in the past. That or I have had the misfortune of encountering issues with back to back guns. Don't get me wrong, I love this gun and the canted stock doesn't particularly bother me since I know that a simple trip to SD will remedy the issue, I was just adding my input so that others will be made aware that this isn't an isolated incident.

After receiving my collapsible stock today I discovered my replacement gun from Benelli is virtually identical to the photo posted by the OP. The jig they use must have gotten slightly out of alignment and I have since compared it to new production guns on Gunbroker and found many to be the same way. In my favor I'm left handed, so the canted buttpad actually fits my shoulder pocket better. I may send it on out to StrangerDanger after the newness wears off, but for now I'm just gonna enjoy the heck out of it since shotgun shells are still readily available around here.

The inside of the barrel just looks like plastic residue from the wad. Not sure how many shells you have through it, but plastic buildup is extremely common in shotguns. Soak a bore mop with Ballistol, run it through the barrel, let it sit for a few hours, then hit the bore with a bronze brush or tornado brush. Don't be at all surpised to see chunks and slivers of plastic coming out of the barrel.

The complaints I have heard are that the rail destroys Larue mounts, instead of the mount destroying the rail. You'll be fine with the factory rail if you can find a mount with full width recoil lug/s. Trijicon's quick detach comes to mind but it's too high unless you run the second position on a C stock. I have yet to find a mount that has full recoil lugs and is low enough to use with the fixed stock.

Sounds like a winner! Thanks for keeping me in mind!

Thanks for taking the time to reply. if you decide the collapsible stock isn't for you please let me know and I'll take it off your hands with no money lost on your end.

Took it to the range today to sight in and it was dead on with the first shot! Very accurate with slugs, buckshot, and ran 2 boxes of cheap target loads with no problems at all. To finish the day I sat in the skeet shack with a nice fire burning in the wood stove and smoked a Montecristo while wiping it down. I LOVE A HAPPY ENDING ?!

Got the replacement in today and it's a beauty. Machining/fit and finish, are exactly what you expect from a prestigious brand like Benelli and I can't wait to hit the range to get it sighted in. A HUGE thank you again to Benelli, Mr. Orr, and all you fine folks who took the time out of your day to read, respond, and follow this thread to its conclusion. Now, if I can just find a collapsible stock I can finish up my 922R conversion and upset the folks on the skeet field by using it for our Wednesday night shoot ?.

That's a beauty right there! Tastefully done without being over the top. Where'd you snag that nifty QD socket plate in the stock? Edit: you beat me to the punch as I was typing LOL.
