s**t DJ, I was chasing a camo 308 7600 for a very long time. They were only available briefly.
Most of those sold here were a blued bead-blasted 22" black poly-stocked version, and the 16" 7600 Patrol, in a great grey-green-black Parkerised finish.
I was also chasing the camo stainless steel, 22" barrel 223 that was sold here or a short while. Hens teeth. I wanted it to use as a full-power 223 walkabout rifle.
The 7615 .223 with the 16" barrel was most popular I reckon, because how short, slim and handy it is. takes all length AR15 mags, 10, 20, 30 shot if you are licensed to have the bigger mags that is.
No things sticking out all over the place, no unnecessary handguards, pistol grips and crap for standing gazing at yourself in the mirror. 10-ahot mags are short and double-stack, as they should be.
There were some blued walnut 30-06, and very few 270 and 243 ones sold here, with 22" barrels, perfect length. And some 30-06 carbines in 18" which were ear-splitters. Made the 30-06 less ballistically than the 22" 308.
As for barrel changing:
Each barrel is fitted to a Barrel Extension, or "trunnion, a solid steel block that contains the locking lug recesses and where the headspacing is done.
Then to fit, this one-piece assembly slides into the solid steel receiver, like a shotgun does, over via high-tensile stud peg in the lower receiver. The "nut" screwing it on is the pump handle peg which the pump forend slides on. A few minutes, if that.
Each barrel is final hand finish-reamed to suit the recievers' bolt, for headspace.
So to make extra barrels that fit the bolt's cartridge head size, you need the barrel extension trunnion, a fitted barrel, and it be headspaced.
In the 223 case head size, you can have 223 and 300BO. Use the same mags.
308 bolt, you can have 30-06, 270, 25-06, 243, you get the picture. All magazines of the different cartridge lengths here fit straight into the one receiver.
The bolts rotate clockwise to lock, and are multi-lugged. Very strong.
But each barrel change will need re-zeroing the scope, because it's mounted to the solid steel receiver.
Triggers are similar to the 870 shotgun, and a polish and spring change can easily get you a 2.5lb trigger. I've done all of ours with a Dremel, a roary polish mop and Autosol steel polish paste.
For me anyway, each time you have to re-sight-in the rifle when changing calibres, that's not on for me. Same goes for the bolt-actions that need you to do this, what a pain.
As each new calibre has a different reason both for you and with the local state Weapons Licensing, I'd just get another complete rifle/scope.
Stuffing around swapping barrels then re-sighting in a rifle each time is not my idea of an efficient, smart idea. Just me.
To me, the pump and button 223 carbines sold here now are far inferior with their aluminium receivers chunking out quickly, trying to look like AR's for the popular tactical market, with their awful heavy, difficult and expensive to fix triggers.
The 7600 series are no more, only ones left are now second-hand.
