Hi!

Basically, i have a Canuck Operator that i've owned for a few years. Great gun and all, but i'm looking to modify the feed port to make it easier to load, as the shell carrier has a nasty tendency to bite my thumb if i'm not using a particular technique when i load shells (Thumb get stuck between the elevator and the front face of the tube). Particularly annoying.

Since aftermarket Benelli M4 Style aftermarket shell carriers are basically non-existent in Canada, i can't just swap it out for a longer one or something.

If you take a look at the feed port of a VR-66 on TNA, that's basically what i want to emulate; a 3-guns style feed port that has been beveled and opened up.

If anyone has any tips on if there is a particular gunsmith in Canada that can do that i would highly appreciate it.

Tac Ord absolutely can do it (their work is top notch) but like you say the cost might not be worth it on a basic shotgun.

They will have an M4 pattern welded lifter too.

Awesome! I see that they have a TTI AccuGuide Extended Carrier that i could potentially use. Only question is would that extended carrier be enough to fix the damn carrier thumb bite. From what i can see, it's maybe just a few mm longer, no way to tell if that's going to be enough.

Truth is i've been eyeing the VR-66, it looks awesome but i really like the looks and telescopic stock of the M4 much more. And ya know... if i can avoid the hassle of having to trade/sell my Canuck, i'd prefer that, it's actually been a very reliable and fun gun.

EDIT: Now that i think of it, the TTI Carrier is flat on it's tip, so would probably be much less likely to wedge a thumb rather than the fork thing on the original.

Fairly sure it would work even on a Turkish M4 clone, they are mechanically almost the same.

The TTI Accuguide lifter will stop the thumb nail bite. We have them in stock for the Benelli M2/M4.
 
Right, so i installed the TTI Lifter.

Basically, it fixed the thumb bite problem entirely. So much smoother and easier to load, and it's pretty much impossible to get the thumb bite now. Installing the lifter itself was easy, but i had a new problem; the lifter doesn't come up far enough upwards to properly guide the shells in the chamber, causing frequent jams with the dummy rounds i've tried due to them not being aligned with the chamber, striking the front of the chamber instead.

The Canuck Operator is mechanically very similar to the actual Benelli M4. There is a few, very minute differences, but i would dare say they don't matter 95% of the time.

One of the small difference is the way the carrier dog is attached to the lifter ( Part 69 *Nice* here: https://www.gunpartscorp.com/gun-ma...otguns-benelli/semi-auto-shotguns/m4-super-90 ). The original lifter dog is attached with a simple, flush pin. The Canuck however, the pin is flared outward (In the tutorial video i saw, they called it a stacked (?) pin), basically vaguely similar to a rivet. However, the pin on mine was extremely stubborn and would not come out no matter how i tried to hammer it gently. So i had to go ham a bit, which bent the carrier dog and the pin. I was able to bend the carrier dog back to where it was and put it all back together with the new lifter just fine.

I suspect that due to the damage of the carrier dog, imperceptible changes to the carrier dog position on the lifter or something along those lines is causing the lifter to not be able to basically lift the shells upward enough to "hold" them in place while the bolt slams forward.

I'm not sure yet on how to fix this. If you have a genuine Benelli M4, i suspect you won't ever have that problem. But i'm all ears for suggestions on what road to take or if parts are available that i could replace the carrier dog. I'm even considering bending the TTI carrier itself upward so that it basically banana up a bit, so that it can properly hold the shells upward right.

EDIT: I'm also wondering if it's an issue that pops up due to the way the gun behave when manually cycling it with dummy rounds. Would have to shoot it at the range with live rounds to see if it works just fine.

Another note: I've been using 2.75 in dummy shells. Something tells me that maybe 3" in shells could work a bit better since they are longer and would have less of a chance to poke outward. Argh, just making a bunch of theories over here.

I FIXED IT!

The problem was that the carrier dog was not able to be brought forward far enough because the TTI Acculift upper tab limit is too far. So what i did is i simply filed it down by about 2 mm, increasing the angle the carrier dog would impose on the lifter, thus increasing the upper reach of the lifter.

Now i'm able to cycle the action just fine, and i don't have shells poking out.
