    Form 1 50bmg suppressor

    After making my 408 can I was ready to make a can for my 50bmg. 50’s are fun to shoot but the muzzle blast is horrendous.
    After seeing this video I wanted one similar in size. And decited to make it 18x3inches dia

    I wanted to make it out of stainless and I ordered materials from online metals.com.
    I wanted to make it light as possible so I ordered the thinner wall .065 in 3inch dia.

    and the bar material to make the baffles

    I wanted the weight to come in at 6-7 pounds and thought the thinner wall would work and using aluminum spacers to cut the weight and provide more strength for the walls. I found some tubing that fit perfectly.

    This would hold the baffles straight and make it lighter.
    Baffles:
    I went for a simple “tac16” design. 6 baffles and spacers. I thought more complicated ones would be heavier and harder to make.I originally was going to have 7 but dropped one to save weight. I back cut the holes to let the gas expand before hitting the next baffle and save weight.

    I started with a .57 hole and ended with a .61 hole in the end. I “tapered” it to help avoid baffle strikes.

    The baffles were simple but heavy to I turned off the “rim” of each one but the first one and it saved me half a pound in weight. The can still ended up being 8 pounds but being 18 inches long and 3 inches dia. I feel it came out pretty good.
    I had a friend of mine tig weld it together:

    It looked like he was working on a drive shaft not a suppressor!
    It was now ready to me fired. My fired has a 55 gallon drum buried in his shop filled with sand and has rubber layers over it to set weapons so I fired a shot to see how she worked! I have to admit I was a little nervous before firing it but I was confident it would work.

    I was pleasantly supprised with how well it sounded. Didn’t ring my hears and had a good tone. I fired a few more to make sure nothing was coming apart then drove out to on open area to see how it sounded away from the metal buildings.

    It was very pleasant to shoot with no muzzle blast and recoil was not bad at all.
    The gun: Original Cheytac intervention (made by EDM arms) with 50bmg barrel conversion from EDM arms. (Switch barrel)

    I have some more detail work to do on the can before I coat it but I’m psyched how well it came out and works. I have about 280$ into it and only about 10 hours of lathe work. The baffles were done on a CNC machine and after programmed took 7 minutes to make each. I love the fact that I made it my self and how well it works.
    did I mention this is huge. I'm 6'7"....

    If you dont mind was your form 1 a trust or individual and how long did it take to get back after you sent off? Ive got one in the works pending right now. Was this done recently? Great job by the way, your .50 bmg is a slight step up from my .22lr but Im tryin.

    I did a trust. I can't remember how long it took. I have had it a while before I got started.
