This will be a little section on my M-203. It is manufactured
by Randy Shivak. I've had the launcher almost a year now, and have experienced
no problems with it. I bought a standard 40mm barrel for it (12") and also
bought a 37mm (9") carbine barrel for it. I had to do a wee bit of
machining on the 37mm barrel for it to load the standard large based 37mm
aluminum and plastic casings. With a little lathe work, it loads just fine. I
bought the quadrant sight from RPB inc. They do sell real quadrant sights, but
fake leaf sights. I managed to locate a leaf sight from a good friend overseas,
so no problem. The handguard is one of those cheap ones bought from Fireballs
inc. With a little dremel work, it makes an acceptable handguard. You have to
take your time and have patience to get it to look right, but once it's done,
it'll look just fine. (See photos below) I've fired many different types
of rounds through both the 40mm and 37mm barrels, as well as had some rather
nice shotgun shell adapters made, which work fantastic. Prices on M-203
receivers vary greatly, depending on where you buy, and if you want new or
used. Here's a photo of me and the 203:
My receiver was featured in
the Jan 04 issue of Small Arms Review Magazine. When originally purchased, the
barrel rails fit snugly. After some lube, and working, it opens and closes fine
now. Here are a few more photos as well as a photo of my 203:
Here's
the front of the launcher. The shortie handguard works well after mucho dremel
work. Leaf sight provided by a friend. Pictured here with two of my 40mm
buckshot rounds.
