You're welcome. On another note, assuming this gun doesn't have a collapsible stock, you are likely only one part away from being compliant since the cc tube comes with a US made follower. You can pick up a FFT disconnector for $35. Installation is simple, then you could sell the compliant shotgun for $1500, possibly more. It would be an easier sell that way I think.

I get playing it safe with regard to firearms and federal law, however I really don't think selling the gun in its current configuration would be an issue. Let me cite the somewhat recent situation Benelli had with the first run of M4 H2Os. A few thousand people bought those before the ATF said 'nope, not compliant' and Benelli had to change their production to include Yankee parts. The lucky ones who got the non-compliant guns didn't have to switch out parts or trade in for a slightly different model. This is because 922r is about assembly, not possession. A notarized affidavit starting the exact condition of the gun (all Italian except the full length tube) at the time of the sale would be enough for a buyer to prove he didn't assemble the gun into a non-compliant configuration. I don't think your idea of selling is bad, and like i said earlier, better safe than sorry. You could always ask ATF, they are actually pretty good about answering questions so long as you're willing to wait for the response. Sorry for the loss of your buddy, and good luck with your sales.

You have to replace four parts with the collapsible stock because the stock and the pistol grip are two physically separate parts. They are only one part with the standard pistol grip stock. The straight stock will only require 3 compliant parts.

Anything 3" or shorter will fire, anything shorter than 2.75" probably will not cycle the action

If I recall correctly, the USMC manual shows the dots on the ring near the base of the ring. On mine, the dots are higher at the vertical center. So my three dots make a straight line

It took mine 8 months, that was August of 2011.

There must be a defect with the detent of the stock if it will engage the notches so that the stock won't slide along the tube and can only rotate one way. Unfortunately, you can't photograph it. Take the stock off and feel the top of the inside of the stock's tube. You should feel the detent as a cylindrical bar that goes across the width of the tube. It should move up when the button is pushed and not move at all if the button isn't pushed. Does the bar feel smooth all the way across? Can you push it up easily without the button pushed? My guess the bar is broken, not to spec, or has a faulty/missing spring.

Thank you, but I was curious as to whether or not the OP could do it specifically with his promag unit. If he is leaving the stock at the install notch, it will freely turn left or right 45 degrees with or without the button depressed. At least that is what my factory c-stock does. If he isn't sliding it to one of the three actual positions, the catch won't properly engage.

Are you able to get the stock into the fully extended and fully collapsed positions?

Only if you want to swap out the standard 5 round mag tube with a full length 7 rounder

Right, since the butt stock and pistol grip count as two parts if you are using the c-stock, you would be able to use the OEM handguards if you like.

So I guess the 'toture test' from the OP has become 'how many of Amsdorf's videos can you watch to the end'

The mods over there already put him in timeout once!

He's sharing his videos with fnforum.net these days

Hey Aaron, I don't have an SBE, but I've read several posts similar to yours. I think usually the first step is to try cleaning and lubing the recoil spring and tube. I have also read that the extractor may need some modification after a certain amount of use on the SBE. If cleaning doesn't fix your issue, I'd recommend calling CS and see what they recommend. Or someone else with some first hand experience will chime in with better advice!

My factory c stock also has a slight amount of play. No sliding play along the extension, just rotational. It's probably less than 1/16" total travel in any of the locked positions, so no big deal. That's too bad you dont like the forend, i was hoping they would be a good option (leaving the side rails off) to add a magpul RVG. Oh well. Thanks for the review

I think 922r applies to all shotguns, not just semi autos, but only if you take the gun out of "sporting" configuration, such as putting on a bigger mag tube (to hold more than 5 rounds) or collapsible stock, etc. As you said, you purchased the gun legally, so it was imported in sporting configuration. If all you are doing is replacing your stock pg stock with the urbino, you aren't changing the configuration, so you should be fine so long as the overall length is whatever the minimum has to be, forty inches or so.

Less time than mine took to ship, but i ordered well before i had the shotgun! Ps: saw you over at fnforum, 17s is a great gun. I got the black, easier to match optics and accessories! Ill get the 16 in fde

I only needed one more part, so I decided to just add the disconnector as well. I was concerned about the hammer, and the pull of the OEM trigger is fine for me. So far, with stock trigger, gisselle hammer and FFT disconnector, I have fired approx. 300 rounds (mixture of rifled slugs and 00 buck). Ive not had any issues with the setup, and I am not yet seeing any wear on the hammer or disconnector. Ill post some pics of the trigger group later, but if you need one more part, I think the disconnector is a great way to go to keep the factory forend

I will just add that the number of foreign parts does not include every single part on the gun, just the ones on the list you found confusing, of which there are 13 on a stock 11707 M4

The charging handle doesn't count, but kips tubes come with a us made follower, which does count, so with the urbino you will be gtg

I think I was being too careful too. What scared me at first was that it looked like the receiver was discoloring a bit due to the heat. No worries though, once it cooled it looked exactly the same as it did before heating. If I were to do it again, I'd probably skip the low setting and blast away on high

Just keeping heating it until you see smoke coming out the end of the tube. It took probably 20 minutes (the low setting on my heat gun, i don't rmember the temp) for me to see that. Twist a bit, heat some more, keep twisting and it will eventually break free

It will never get through to some people I fear...

You wont be disappointed. In fact, I was so sure I wanted his tube I ordered mine about 6 months before I even got the M4. Perfect match on finish, and I didn't have any issue with the wait (as it was stashed under my bed for a few months when I got it anyway)
