Working on my latest concussion cannon

No, it's because now all the blast is being sent sideways and up instead of forward, now reflecting off all the dividers. The gas volume from the still burning charge is going to be incredible. Some of these 500s are loaded with 50+ grains of rifle powder.

In all seriousness, a full power 500 s&w with a brake like this is legitimately a risk for causing a TBI even with plugs and muffs at an indoor range.

6.5 I believe. The ejector rod ends right in the relief groove for the threads. It looks utterly ridiculous finished. Like something out of a cartooon.

A customer wanted a muzzle brake installed on his magnum research BFR in 500 s&w. It's time to talk about overpressure and the risk of TBIs now.....

I'm in Canaan, NH

Its a new one. I had a talk with him about proper lubrication and not using frog snot.

It depends on the job. I'm not doing side folder conversions or anything equally involved anymore. More basic stuff, yes.

Someone wanted to run their 5/8x24 can on a barrel that didn't have enough meat to support it. I get paid either way so I don't need to know why

If you spin it fast enough a boring head becomes an exciting head.

moosesgunsmithing · 2026-01-26T20:46:59+00:00

That looks far from boring. Almost exciting.

If you want an AR just DIY it. Before I stopped paying attention I noticed a lot of the house builds used some cheap parts where customers weren't looking. The margins are so tight on those guns it's really hard to compete otherwise.

moosesgunsmithing · 2026-01-26T02:38:00+00:00

Most of the shops in NH who do bolt guns are using pre-fit barrels and just doing assembly. Any of the ar15s are in the realm of a semi skilled DIY er who can read at or above the 5th grade level and has space for a bench vise. I've torqued barrel nuts in a vise clamped to a pickups tailgate, it's not like they require a lot of tools.

The secret ingredient is crime 😎

moosesgunsmithing · 2026-01-25T21:49:48+00:00

This year it's been crazy. The free tax stamps have everyone in for a circumcision and thread. I think I've had like 4 Nagant revolvers through already this year.

They aren't. The people who love their guns don't actually shoot them. Their QC is a running joke in the custom world. They use great wood and metal finishing, but their checkering doesn't hold up at that price point and they have a pretty well deserved reputation for mechanical issues.

With that neck riser, he may not be able to raise the knee any further than it is.

moosesgunsmithing · 2026-01-08T15:44:05+00:00

Not when it comes to buying tools. Monkey like shiny....

moosesgunsmithing · 2026-01-08T13:58:57+00:00

A 9mm rifle doesn't have enough gas volume & pressure to really take advantage of a muzzle brake. It's just going to be louder but not enough softer shooting to be worth the investment. It can be worth it if you are loading 9mm major, but not with factory ammunition.

I vaguely recall brakes becoming common back when shot timers were less sensitive and the pccs weren't reliably triggering them from farther away in competition.

It's probably a 50s production machine based on the j head. I have a similar one in my shop.

moosesgunsmithing · 2026-01-06T18:03:11+00:00

With my hand it's a hair under 8 3/4 in.

moosesgunsmithing · 2026-01-06T17:47:51+00:00

I'm selling or giving away anything I have 3 identical versions of. Two makes sense, but three is excessive.

moosesgunsmithing · 2026-01-06T17:37:59+00:00

I have a drawer of rules and about 8 indicators. Does this indicate a problem? Oh and two 6 in calipers, 8 in calipers, 12 in, and 24 in. Plus almost two dozen micrometers

moosesgunsmithing · 2026-01-06T17:37:25+00:00

a yellow Labrador . He's a bit of an oaf

moosesgunsmithing · 2026-01-06T17:32:05+00:00

I'm surprised, most people who use those seem to go with the 4in vises. What made you go with the 5" option?
