various open-bolt blowbacks. Spyders, Illustrators, Black Draguns
My VM is the EXC version. Venturi bolt, factory expansion chamber, bottomline ASA, sight rail, fieldstrip screws
with a stock VM, a regulator, bottomline ASA, and aftermarket venturi bolt are helpfull add-ons. The VM also lends itself very well to usage with a scope or sight.
Stable to shoot.Extremely durable.Accurate.Intimidating.
Heavy. Tough to get parts for.Hard to adjust fps.Poor shots/CO2
The VM comes in 3 standard configurations - [Stock] with horizontal tank under the barrel, [Magnum] with front and rear ASA for running dual bottles, ambidextrous feed block, sight rail, and the [EXC] with factory expansion chamber, raised sight rail, bottomline ASA, field strip screws and ambidextrous feed block. Most VM users immediately add personal touches - making for almost no 2 VM's being the same. The gun is heavy, has a noticeable kick when fired (due to an oversized hammer), a burly look, and comes stock with an unported brass barrel. The fps can be hard to adjust using an allen wrench down the barrel and special Sheridan valve tool until you learn the drill. Vm's are the posterchildren of durable paintball guns. Throw them on the ground, bury them in the snow, wade through a pond, then keep shooting. Overall, if you don't mind doing a little maintenance now and then, they are an excellent, albeit, outdated marker.
I gave this product a 7 in stock-form. The VM68 is a durable workhorse that spawned hundreds of blowback clones (Spyder/Excellerator/etc), and will continue working in all conditions after most others fail. Upgrades become harder to find with each passing year. Being a somewhat modular design, the VM can be personalized in a myriad of configurations. The weight and general bulkiness of the VM tend to keep many players away from using them. That just means a few more for those that know "the real deal" when they see one.
this guy knows what hes talkin about and this is a GREAT review, id like to see more information about like the specific pressure numbers and shot patterns it would put out but over all this review is great.............
the best way to control the Velocity on a VM is to scrap the expasion chamber and install a High pressure regulator. Open the velocity adjustment screw in the bolt so that the inlet hole is wide open. Use the adjustment on the reg to set your FPS. Works great on mine. I use an Air America Vigilante Regulator(not the LP version). My shots vary +- 3 fps. Ive been playing for almost 20 years and I still use my VM today. They are indestructable!
