TURKNELLI FULL LENGTH magazine tube

The tube is just a tube, until such time as it is installed on a shotgun. Then it is a magazine and needs to be blocked to hold less than 6 3 inch shells. The onus is on you, the owner, to ensure it meets the legal requirements.

Thank you.
That is exactly the answer I was looking for.

Also...based on my research to date (about 1 week's worth so far), it is my understanding, that some base clones have the exact M4 gas piston layout (removeable by using the charging handle to unscrew them), while others have some kind of a spring running through them and screwdriver needs to be employed?

I'm very much a believer in not having to use any tools (aside from a bullet tip) to field strip a military grade firearm, so this is anothet sticking point for me.

Would someone be able to clarify if the S&J base clones have the real deal gas piston setup, or are they of the "screwdriver" kind?
 
The last batch of Turknellis that SJ recieved have the proper gas plugs, as I bought a set to retrofit my canuck operator. The screwdriver stylr is terrible. I had to use a cloth and a vice grip to remove the left one from my shotgun. That was the Operator that was sold after they stopped selling the P4 Kommando. I do not know if the newest Operator still has the poorly designed gas plugs.

Those are takeoffs from the last batch.

I hope that the next shipment does indeed have the correct plug/piston.

I will deffinitelly approach someone at S&J to confirm this prior to purchase...I would think that the correct gas piston setup would likely be near the top of the list of every shotgunner who's looking to get one of these?
 
far as i can see the canuck operator and sulun arms m4 have different threads on this parts, can this be installed on an sulun arms m4 clone?

5x 3 inch shells is 6 x 2-3/4 shells so its still legal since its a 3 inch chamber gun!

This one does not add up for me...unless I'm missing something?

5x3 inch =15 inch
6x2.75 inch =16.5 inch

Seems like another 1.5 inches would be needed to fit 6 of the 2.75 in shells?

I'm not a lawyer so don't take my word as gospel but...

you can plug your mag tube with enough length to fit 5.9999999999x3" shells. As long as the 6th won't fit you're good to go.

Make it 5.9x3" just to account for ammo manufacturer size variations. (see post below for actual measurement)

being just short of 6x3" leaves you with plenty of room legally for 6x2.75 in the tube...

Make it 5.9x3" just to account for ammo manufacturer size variations. 17.7"

being just short of 18" (6x3") leaves you with plenty of room legally for 6x2.75 in the tube...

exactly
 
You guys are all trying to calculate 5.9 x 3” when that’s the opened length. You got to calculate using an unopened 3” shell spec from Saami which is ~70.1 mm max which is 2.76”, this x 5.9 would yield 16.28”. If you did 5.9 x 3” = 17.7” you are so screwed. ILLEGAL ILLEGAL ILLEGAL!

you're right about unopened length, oversight on my part, i changed my posts to remove measurements, but the message is still the same!

I’m glad to help. It’s super confusing with all the opened/unopened lengths, different unopened lengths, different shell size and all.

Let me throw in another catch, is your magazine capacity limited by the compressed length of the spring(not from follower contacting the end)? Meaning if you put in a weaker spring with less coil, are you going to go over 6.0 of 3”? Better measure capacity with follower only without spring to be safe.
