Do not try this – it can cause injury or death and is not normal use nor covered by the warranty. Barrels of this length are spewing unburned powder. Use 10 inches or longer for anything real.
The suppressor had no damage except that nearly all of the finish vaporized. There were no baffle strikes. The blast baffle was fine, and the end cap had no errosion.
Robert – that is nuts. The detonation and the flames around the mag would have really tightened me up. It seems like when doing R&D that is dangerous it might be a good idea to use a fixture and remotely fire the gun.
When I went to the range that day, I had no intention attaching a beta mag. Someone else there had the beta mag, and I though it would be cool. The worst thing I expected was a baffle strike from the heat.
My can was already hot and baked the alumahide off before the beta mag. I didnt expect it to get red, and had I seen it turn red I would have stopped immediately.
In the end the OPS can bulged 50 thousandts(total) out the sides and 25 thousandths(total) on the top and bottom where it turned orange. It seems to have had no effect on how it suppresses or accuracy.
I have no intention of ever doing it again with any suppressor on a barrel that short.
Interesting where any thread related to a suppressor goes. I have received a few emails calling bullshit on my video - the mag must not have been full, I shot in bursts so it doesnt mean as much, the can was destroyed and didnt really shoot those groups.
I just did it during a day at the range, spending ammo with friends.
If someone thinks the AAC is a better can, great. I sell what I believe are good products. I sell the AAC SCAR-SD, which I make much more money on than I do the OPS cans, so it dont bother me if I sell more AAC:)
Buy what you want, for my own “cool” factor I like OPS cans.
I was not making fun of ADCO. I wanted to make the video because I enjoyed theirs, and because a guy on AR-15 said “I dont think an AAC SCAR-SD would hold up. That could be a health hazzard but may be fun to find out.”
We tried Cerekote and it is softer than KG and skuffs easily. So KG is better most of the time. Black Oxide offers no salt-spray protection and does not look very good even when new.
Yes. I wish I had videod the flash/concussion without the can on it. It is a-mazing. It would really show how punishing a 7.5 can be. The flames from the magwell is unburned powder detonating. It builds up in the can. Another suppressor maker told me he has blown up a few cans from that. A 7.5 is just a novelty rifle and I only use it for extreme testing. My real rifles are 10.5 or more.
There was no damage in the can and no baffle strikes either. This was just a warm-up video with my old can. I will make sure to photograph the new can that I put more than one Beta through. I am worried about the rifle though and think it may melt the barrel.
That is a 500+ degree Silicon mitt. Silicon is used for the plumbing that connects a turbo charger to the intercooler on a car. It is amazing stuff and stays much cooler than my leather welding gloves.
BTW, it is not luck that the can did not melt. That was designed into it with very specific choices of materials and structures. If I ever find a way to make one melt, I will further have the design tuned so that the rifle always breaks before the can.
It looks like one of those silicone oven mitts my fiance and I put on our registry at target.
Yes silicone tubing is used in the plumbing between components in a turbocharged car but that doesn’t mean it will stop molten shrapnel in the event the barrel or suppressor blow. It’s used because it is flexible, won’t get old and crack and can handle the pressure- not so that it can contain turbo compressor impellers and parts if one decides to blow.
Robert- don’t do that again. Like it was mentioned before, use a fixture and make a box like those goofs on mythbusters do. It will be a fun project that I know you will enjoy. Then you can use it over and over for tests like that. At least remotely fire your first attempt at anything like that. LaRue makes tough stuff, but that baseball cap, your motorcycle jacket and oven mit wouldn’t have prevented you from getting injured if anything had gone wrong. It looks like you were worried about getting burnt. Looking at that video, an explosion looked possible and usually explosions inolve high speed metal, none of which your gear could have helped you with.
I am making a polycarbonate shield. I want to try a silencer with Grade-2 Titanium construction or parts. Also I am looking to try some thread-together with Locktite 303 stainless models.
