5.56x45 NATO (223. Remington) v 7.62x51 NATO (308. Winchester) rifle.
I've made it look like Sako TRG rifles.

This rifle is made mostly with loose parts, so its pretty laggy. Also, I have some problems with the 308.Win. cases - they are getting stuck after collision with other objects.

To Shoot:
1. Pull the mag in. (Rifle is chambered for 308.Win. by default)
2. Operate the bolt to chamber a round.
3. Pull the trigger.
4. If the mag is empty, remove it by using mag release lever. (its inside the trigger guard) Mags can be easily refilled, just load new rounds into them
223.Rem = 7rds. capacity, 308.Win = 5rds. capacity.

IMPORTANT
To change rifle's caliber:
1. Move the bolt lock downwards. (its right next to the bolt knob).
2. Pull the bolt out.
3. unlock the barrel. (2 takedown levers on the handguard)
4. Pull the barrel out.
5. Pull the second barrel in, and lock the takedown levers.
6. Pull the second bolt in, and move the bolt lock up.

This rifle was just a little experiment, so its not very well made, but you can try to play around with it. Also, I've been planning to make 3-rd barrel and bolt, for 300. Winchester magnum, but as you can see, there are only 2 barrels and bolts.
Also, barrel changing is very frustrating, so be patient.

[EDIT] fixed the 300. Winchester cartridge.
