Sawed off / chopped barrel for 500's
Hello all. I have not seen much info about cutting down or sawing off barrel's here, so I checked YouTube and some other places and just bit the bullet and did it. The original gun was bought used for $149, a well worn standard Mossberg 500 12ga. with hardwood stocks and a 26" vent rib barrel with modified choke and a bead sight. I decided it was cheaper for me to cut this barrel than buy a new 18" one for $80+/- since I have other guns to take the place of the 500 12ga. If I ever bird, squirell or rabbit hunt I'll use a 20ga. If I hunt larger game I'll use a rifle or the 20ga. with slugs or even this cut down 12ga. if it still patterns well with buck or slug.
I disassembled the gun completely, cleaned the metal innards, polished the wear spots, lubed and reassembled with an ATI front fore-end and pistol grip (which I already had). I degreased, then used a dollop of fluorescent orange paint in the worn out safety dot hole and sealed it with clear enamel nail polish to make the safety shine. I also filed/buffed down the sharp edges in the bottom loading port and touched up with aluma-black.
I added the small loop of leather strip to the rear grip screw to allow me to hang the gun on the back of a door on a hook, nicely disguised with a robe over it.
I left the vent rib attached so that I could mount the HiViz glow sights (about $25 total) which in conjunction with the small harbor freight push button flashlight taped to the side of the barrel allows me to see which way the barrel front is pointed when held at the hip; or as a glowing 3-dot combo when used in conjunction with a regular rear stock if aimed from the shoulder. The rear sight is clamped down onto the rib with 4 screws and blue loc-tite. The front sight is magnetic and seemed pretty strong, but as I planned on not being especially careful with how I handle this "beater", I went ahead and used some hot melt glue on the plastic sight base and vent rib to make it semi-permanent. The cheap $2 AA flashlight is simply duct taped to the side. I made sure to find something with a button rather than a "twist on". Yes, I know it's looks ugly and is not strong enough to be considered a tactical light, but I mainly just wanted something to illuminate a person in my house and add enough ambient side light to make the front sight glow bright.
Cutting the barrel was easy enough. After carefully measuring to make sure I had at least 18" and deciding where to cut the rib off, I used several layers of masking tape wrapped to protect the barrel finish. I left the barrel longer than the rib to help protect the sight and rib. I clamped vise-grips above and below the spot to cut (not squeezing the rib) and mounted it all in a wood vise. The vise-grips have flat sides which made the 30 tooth quality hacksaw blade run straight and true by going slow and easy. The more care you use cutting, the less time you waste trying to clean up a crappy cut with teeth marks! I cleaned up the crown with large felt wheel "bobs" using first rough, then fine compounds in my Dremel, which took out the few teeth mark scratches left. Flitz polish on a 3rd felt bob finished making the cut mirror bright and ready for cold blue. (*used the Flitz to polish the interior parts which smoothed the action an AMAZING amount).
Hope this helps anyone who's pondering the same question of whether to cut or not.
