Warning: Fellow survivalists and gun carriers, whatever you do, DO NOT build this homemade ACP just for fun or curiosity’s sake! It is illegal to make, and not only that, it is downright dangerous.

How to Make a Homemade ACP (Hypothetically)

Youtuber Royal Nonesuch shows us how it is possible to make a homemade ACP .45single-shot pistol. Read on for the details.

YouTuber Royal Nonesuch is at it again. This time, he’s got something really cool and functional in the form of a .45 ACP handgun he, once again, built in his garage with nothing more than a few parts and some really shoddy-looking welds.

Of course, there was some (okay, a lot) of ingenuity involved, but it’s no surprise based on what he usually shows us in his videos. Seriously, I wish I had half the skill this dude has.

It took me two 80% lowers to get it right when I built my homemade AR-15, and I’ll still have to read the instruction manual next time I do it.

But this isn’t about me. Instead, it’s about this striker-fired, single-shot, break-action, .45 ACP handgun. While it’s ugly as sin, it seems to work well and is at least somewhat accurate for a gun with no sights.

He didn’t supply us with a build sheet, so we’ll try to break it down the best we can. Please feel free to point it out in the comments section below if you see something I don’t.

Breakdown of Parts and the Improvisation Process

For the apparent parts, he said he used a paintball gun lower. I’m not sure how well it will handle the recoil from such a heavy caliber self-defense cartridge, but so far, so good.

I’m sure these are more plentiful than an actual handgun lower, plus the lower (where the grip is) is what you consider a solid gun with a serial number. So, if you buy a complete pistol lower from a real handgun, you’ll have to go through a background check for it.

He used an accurate .45 caliber barrel that we (and many gun experts) always recommend over a pipe for many reasons.

First, a pipe can have weak spots, which is not good.

Second, pipes aren’t rifled and are much less accurate. Rifling helps stabilize the bullet pre-flight, and if it comes out of the barrel tumbling, it loses accuracy.

Third, not having a rifled barrel may be illegal.

You can find a barrel on everyone’s favorite auction site for $40 and-150. You can find the things for making a gun in a hardware store. So, there are many nuts and bolts on it, increasing its hideousness tenfold.

One such bolt is used to hold the barrel to the lower. If the bolt is taken out, the barrel breaks open (flipping backward) to be un and re-loaded.

Final Thoughts

Unfortunately, as stated above, he didn’t provide a build sheet for this, and there are reasons.

My guess is that he doesn’t want to be held responsible for the idiocy of others.

Making a gun can be dangerous if you don’t know what you’re doing. But it can’t hurt to speculate a bit, right?

His firing system (and really, the entire pistol) seems similar to a Ruger Mk 3 or S&W Victory, minus some parts usually present.

The hardest part to figure out is how the “firing pin” works when he attaches it to the trigger group. This loading method is tedious, but remember this was built in a garage with a welder and some spare parts.

This homemade ACP is grotesque and gorgeous all at the same time. Much respect to Royal Nonesuch for this creation would be a great survival tool/apocalypse gun.

Again, if you can enlighten us about how he put the rest of it together, I would like to read about it in the comments below.
