Some deepen the cuts on the sides of the catch to improve its flexibility but I’ve heard catches fail if too much is removed. I prefer to bend the catch so you have the least amount of contact securely retaining the shells then grind/shape/polish the edge of the catch so it more evenly contacts the shells. It’s a LOT of trial and error (I’d recommend having another catch on hand or working very incrementally)… the first time I tuned a catch, I test slammed the stock on the ground and all the shells backed out of the tube - kinda funny in retrospect. Took it apart, lessened the bend, retested, and got it to where I could not induce a catch failure but it was smooth to load and unload. I’ve done this for my M4, M2, Beretta and Franchi. No issues to date.

I had to “tune” my shell catch to get it to where it was smooth.

A vise will make your life easier. As for heat, I used a MAPP torch but don’t apply the heat directly to the receiver (you will melt it). Rather, apply the heat indirectly onto the steel recoil tube near the retaining nut.

Got mine installed in 30 min… a lot faster when you don’t have to deal with the factory loctite. Tip: lock your stock onto tube position #1 when threading the tube into the receiver. Keep turning until the stock won’t clear the receiver. Back off the tube until the stock is oriented correctly. That’s the final tube installation depth.

It’ll be nice to spend some modding time with my M4… other than practicing with it I haven’t had a chance to work on it lately. Great opportunity for a detailed breakdown/cleaning.

I’m ready… take my money already!

Can’t wait to try one!

Is the stock new?

Make sure to do a sear check.

Not an owner and the description says “Made in the USA” but it’s described as “discreet”. Not sure I’d agree with that. However looks perfectly usable as a range bag.

I agree that there are quite a lot of 1301t in classes. It was less punishing than the m4. I have more appreciation for field stocks as reloading with a pistol grip is slower (for me). I’m going to try my next class with a field stock m4 for comparison. Imho both are excellent shotguns with a reliability edge to the m4.

Unfortunately many of the parts are ITAR restricted so IWC won’t sell directly outside the US.

Congrats! The easiest 922r path is a US made trigger group. That’s the hammer, trigger, and disconnector. Those 3 parts will allow you to install the extended mag tube. You can go FFT but I much prefer Briley for the money as you get an “improved” trigger for about the same money. Just send Briley the entire trigger group and they’ll install it for you.

Thanks. I highly recommend installing the Beretta 1301 pro lifter. The difference is it keeps the lifter up and out of the way. Makes reloading super easy.
