An extension tube? What do you mean? You have a full tube on there...

[rooky]

this tube is 5+1...

[rooky]

I want kip tube 7 + 1 and it seems my tube is full size but only hold 5 + 1

[rooky]

Please anyone know why my fullsize tube is 5 shell capacity and the one kip and other sells are 7 shells?

[Super33]

5+1 means 5 in the tube + 1 in the chamber. 5+1+1 is 5 in the tube, 1 in the chamber, and one on the rail. However you say it, that first number is the total number you can fit in your magazine. My M4 will hold 7+1+1 of 2 3/4" shells. When I had the dummy extension it would only hold 5+1+1. Obviously using 3" shells will reduce those numbers.

 

Pay close attention to the shell length. You should be able to fit seven 2 3/4" shells in that tube. Some 2 3/4" shells are actually slightly longer than that and you'll only be able to fit six in there. Are you loading 3" shells? With my full length mag tube I can fit seven and that last one juuuuuuuust fits in there. If I use Royal low recoil OO buck I can only fit 6 even though they're 2 3/4" shells, they're maybe 1/16th of an inch longer than regular 2 3/4" shells but that's enough to keep that seventh shell from joining the party.

maybe you have some sort of limiter in the mag tube?

This conclusion seems to be the best. But, i don't see any reason why one of Kips tubes would not fit. In fact I would bet money that if you bought one of Kips full length tubes or one from FFT it would fit with no problems.

It'll fit. Unless Kip completely messes it up.
