Simple cone is easy to clamp in a vise and drill from the back side. I wouldn’t think you’d need a jig for that one

Some of us are the people they test "fool-proof" stuff on. And, when I comes to things screwed onto the end of a firearm, I prefer not to be the test fool...

So I'm watching the video on the website for the 22 drill fixture and he mentions the fixture is two pieces. I'm looking at mine and it is only one piece. There is a line scored around the entire fixture but it is superficial and the halves don't separate. Did they change the design? I can't see the back side of his fixture in the video to see if it looks like mine would.

They seperate, try harder. I can see the pins that the top piece slides onto in your pics. Those 2 bigger holes are what bolt.the top to.the bottom...

Got them separated but it took quite a bit of force. These titanium cups are crazy hard to drill. Lubed well, tried slow...fast...took over five minutes to do the first cup and my drill bit snapped on the second.

You put the cups in the right way, like in the video?

Yeah, it took me about an hour to drill all mine out. The bit tends to grab as it breaks through the cup. It chipped one of my flutes on the last cup. Those short 9/32" cobalt bits are ~$10.50 at McMaster.

I drilled out multiple kits now and have had no such issue... slow, firm pressure and using a pecking technique, tap magic applied to top of cup and tip of bit initially and a squirt between each peck...zero issues.. jig secured in my vice and bit in my Milwaukee M18 Fuel. you're having a tough time over there.

The pain of waiting almost a month for something you want so bad and then getting approval but being stuck overseas for the next two weeks. These two were submitted on 9/15 and 9/17. F73E3DBC-DBE9-4124-8748-50BD9B179167.jpeg

My Form1 was approved and I finished my can.

I noticed that the baffles were quite loose in the tube with ~.010-.012" of diametric clearance. I cut a sheet of steel shim stock the length of the can and rolled it around the baffles. A little tricky at first to get everything assembled but now I have a good concentric fit and a fouling barrier with the tube so I can push everything out even when filthy.

So far great performance on my M&P 15-22 with CCI STD ammo. I'm going to try the new CCI poly coated ammo and see if it cuts down on fouling.

You will want to remove that shim so the baffles will come out for cleaning. Powder and lead build up in the baffles you need the clearance to remove them . The end caps hold them in place ,and the baffles swell some as you tighten the caps.

NHR I noticed the same thing but even with a little bit of play between the tube and baffles there should still be plenty of clearance with the 9/32" hole

The point is that the shim comes out with the baffles, and then unrolls so it doesn't matter how much buildup there is. Similar to the Sico rimfire can

That’s really rolling up a burr on the top side for it being a new bit. That leads me to believe you might be running it too fast or not enough lube. If you get the bits hot, they dull a lot faster
I'm thinking I got a bad bit. The new one came today and it is working way better than the bit that broke.

You want to make sure you don’t heat up the Ti. Push firm and get metal removal. If you have lube and a sturdy machine keep going. If you have a drill press or hand drill just peck it repeatedly. If you have the bit touching and not cutting you are making things hard on yourself. It’s easy to go light on pressure and scrape the bit on the surface which dulls the bit and heats/hardens the Ti.

I can't remember if you said that you received your stamp yet, but I am really looking forward to hearing your thoughts on this after you have it drilled and have some rounds down range. This is obviously not a good candidate for hunting, but it would probably work just fine for a bench rifle.
Finally received the stamp for the 223/308 trap. Got back from two weeks in China and within 3 hours from getting off a 19 hour flight I had the baffles and end cap drilled. I was very excited. I wish I had weighed it after drilling because it feels way better now. I will try and bring it into work this week to do so.
Took it out to the range the next day and installed it on a 20” barrel 6.5CM AR-10. Not my first choice since a gas gun will be the loudest but I still haven’t gotten the 3/4-24 threaded cap for my bolt gun. I was shocked at how quiet it was. I figured I would still need hearing protection but that was not the case. The 35 rounds I shot where very comfortable. Now it was a very windy day so I don’t know if that had anything to do with it and it was hard to get a good feel for the sound. The other thing I was surprised about was the accuracy and the point of impact shift. It was probably the best 10 shot group I have ever shot with the cheap $700 PSA and it was only 2” low. Very happy with it and can not wait to try it on the Desert tech. 980EF5D7-0B2A-4EB7-8BFF-F21EC5A2C54D.jpeg

What .22 kit is that?
How reliable has it been?
It is an Advantage arms conversion. https://www.advantagearms.com/

It has been super reliable until this last weekend with the new threaded barrel and new ammo. Not sure who the issue is with at this point. I’m guessing it’s the suppressor ammo since both the new barrel and my AR were having issues closing the bolt all the way.

The regular CCI Standard velocity is subsonic out of a short pistol barrel. I would give that a try. It may give you enough pressure to run the action reliably while still being subsonic.

I've been using the CCI clean blue poly subs in my M&P 15-22 with no issues. Also shot 50 rounds of CCI Suppressor 45gr HPs with no malfunctions. These were surprisingly accurate. The Winchester 45gr solids functioned well but had garbage accuracy. Even from a 15-22
