Awesome Video above.
Pre-ban tactical carbine model with multi-position sliding stock, FH/muzzle brake, and fwd "Kelly" grip.
The charging handle is on the left side of the receiver/frame.
The best mags were the smoke semi-translucent. 23 turns for the 100 rdr. (over torquing would break the spring).
147 gr. bullets were reliable, as well as +P due to the HK MP5 style DRB action.
They made a Weaver style rail for above the barrel/handguard and a Weaver optic rail above the mag.
C-More railway was the lowest profile RDS to use to prevent that crazy optic height over bore issue.
The ban era solid fixed stock is shown in this pic, as is the plain muzzle.
You can also see the bolt stop/BHO just above the right side of the trigger. The safety lever is forward of the trigger.
They made an ambidextrous nylon Uzi style shoulder harness for the M-950 pistol, which allowed for strong side carry of the pistol loaded with a 50 rd. mag. and an adjustable pouch for a spare 50 or 100 round helical magazine on the support side.
Male end snap buttons screwed in on the back optic mount holes, and the holster used female end snaps.
This pic shows the crank style magazine loading device.
They made a cordura nylon gravity fed brass catcher that slipped over the bottom ejection port that held up to 100 empty casings.
For the early 1.0 models and ban-era models, an OEM UZI flash hider works great on their muzzle.
The set screws will fit into the notch where Calico used a roll pin for securing their muzzle device.
