Previously few years, a “do-it-yourself shotgun” package has develop into standard, billed as a survival gun.

Constructing a Pipe Shotgun

A number of retailers carry this package. We ordered ours from Bud-Okay for $130 with free transport.

The pipe shotgun bundle arrived through FedEx Good Options, which means that FedEx did all of the heavy lifting getting it to inside 20 miles of me and transferring closing supply to my native publish workplace. Bud-Okay packaged it properly sufficient, however after opening it up I spotted there was no instruction sheet.

This wasn’t a giant deal, because the package is simple with a video on the corporate’s web site. When compiling the gadgets wanted to complete it up, I went to double test on the web site what a “jam nipple” was and realized the firing pin wasn’t included within the cargo.

Bud-Okay’s customer support desk started searching for extras of their warehouse. In the event that they have been unsuccessful, they’d have me return the package in trade for a brand new one. A number of days later, they suggested that the producer would ship out the lacking parts instantly. After a few week, it arrived.

Completion of the package requires the next ½-inch pipe elements:

  • one ½-inch tee
  • three ½-inch caps
  • two 4-inch nipples
  • one 3-inch nipple
  • two 45-degree elbows
  • one 90-degree elbow
  • two jam nipples
  • one 5-inch nipple

The one elements that have been considerably tough to seek out have been the so-called jam nipples. These are quick nipples which are utterly threaded. I discovered them below quite a lot of names similar to zero nipples and flush nipples. Maybe jam nipples are a colloquialism in sure elements of the nation or an older plumbing time period, however I couldn’t discover them below that title in shops close to me.
After a fast journey to Residence Depot and $32 later, I had all the things I wanted to place the Pop-A 410 collectively.

Meeting took about quarter-hour, if that lengthy. One of many trickier issues to get proper was making certain that the angled pipe connectors aligned correctly. They may line up completely whereas solely greedy two or three threads, however then could be completely out of alignment when tightened all the best way down. Lucas Oil Gun Grease and a small pipe wrench at the side of a vise acquired all the things correctly into place. I threaded so far as I may, backed off, and repeated with a purpose to grasp extra threads to make it sturdy and straight.

After you have an thought on how all the things strains up, you can also make it semi-permanent by utilizing plumbers’ tape, Loctite, or one other adhesive. Some builders have used JB Weld for a extra everlasting repair, however that could be extreme.

An important piece of this meeting is the ½-inch tee piece. This acts as your receiver, for lack of a greater time period, and the firing pin ought to be capable to cross utterly by it.

Above: For lower than $35 in pipe fittings, you may full the Pop-A 410 package and have a single-shot shotgun.

When completed, you could have principally a two-piece pipe shotgun composed of a chambered, spring-loaded barrel, a do-it-yourself receiver containing a set firing pin, a do-it-yourself inventory, and pistol grips. A “security” is included within the type of a clip that inserts between the firing pin and primer, connected to a brief piece of twine so that you don’t lose it. There’s no sighting system, however the ahead pistol grip has a Weaver-style base so you may mount a crimson dot or seen laser. A brief sheet steel screw with a rounded head may make for an improvised bead sight.

You’ll be able to depart the Pop-A 410 unfinished, “within the white,” or you may escape some Krylon, Duracoat, and even Cerakote when you really feel fancy and coat it in a protecting end.

Firing the Pop-A 410 Pipe Shotgun

To fireplace the Pop-A 410 you load the chamber, shoulder the pipe shotgun, snatch the ahead grip, purpose, and slam the barrel rearward. The influence of the firing pin in opposition to the primer of the shell causes ignition and fires the projectile.

The primary spherical was a little bit of a doozy. The thought that saved going by my thoughts from the second I loaded the chamber till I truly fired it was, “Will that galvanized pipe becoming and that two-piece barrel meeting that I purchased be sufficient to deal with 12,500 to fifteen,000 psi?”

Above: Taking pictures the Pop-A 410 pipe shotgun is a bit difficult because of the lack of a set off, however not tough. Shoulder it, take purpose, and slam the shell rearward into the firing pin.

It turned out that it was. The burst ranking on this kind of pipe is 21,000 to 26,000 psi, whereas pressurized. The quick impulse of firing a single spherical of ammunition performs a task, too. Nonetheless, nobody will get “tens of millions of rounds out of this” weapon. I fired near 150 rounds of varied birdshot, buckshot, and buck and ball shot, with out incident.

Past the enjoyable issue, this can be a firearm of final resort. As an example, when you needed to construct one thing out of scrap to forage for birds and squirrels in a survival state of affairs. Or, in a darker state of affairs, when you wanted to make one thing with a purpose to take out the opposition and scavenge his weapon.

Various Weapons

Whereas this was a enjoyable venture, it’s a bit costly for what you get. It’s principally a slam-fire .410. You’ll be able to stroll away with the satisfaction that you simply constructed a firearm by yourself. Plus, placing it collectively might present a greater sense of how firearms work, together with the satisfaction all of us get at any time when we construct one thing with our personal two arms.

Above: For the price of a accomplished Pop-A 410, a shooter can choose up a purpose-built shotgun in the identical caliber, many made earlier than 1968 additionally lack a serial quantity similar to this single-shot Winchester Mannequin 37 and an over/below Stevens Mannequin 420.

In case you’re primarily intrigued by the truth that you may construct a firearm with out a serial quantity and questioning why you’d make investments the money and time in one among these, there are different alternate options.

For instance, there are untold numbers of firearms, largely shotguns and rimfire rifles, constructed earlier than 1968 that haven’t any serial numbers and could be bought for a lot lower than what was invested on this venture. These aren’t simply rusty single-shot cracked-stock scatterguns, both.

Through the years I’ve acquired single-shot shotguns made by Hopkins & Allen, New England Firearms, Harrington & Richardson, Iver Johnson, Savage/Stevens, and Winchester for lower than $90 every — and within the case of the Hopkins & Allen and Stevens fashions, lower than $40. An over/below Stevens 420 in .410 made 75 years in the past set me again $110, and a bolt-action Sears 12-gauge price me $60. None of those firearms have serial numbers; neither do a handful of twenty-two bolt-action and single-shot rifles I’ve acquired through the years.

Closing Ideas

Above: It will not be a collector-grade, heirloom-quality firearm, however the Pop-A 410 survival shotgun represents a studying device and a light-weight firearm that could be sufficient to maintain you alive.

Any ready particular person ought to have low-cost firearms readily available, as a result of they’re low cost, straightforward to discover ways to use, and could be loaned, bartered, or in any other case utilized within the occasion of a large-scale long-term catastrophe.

The Pop-A 410 survival shotgun can fill this position, however it’s extra important alongside the strains of a first-time gun-builder understanding how a firearm could be constructed, together with the inspiration for concepts on the way to construct your personal, ought to you end up in a state of affairs the place making a firearm from scratch could also be your solely choice.

Look at your ammunition sorts readily available and see how they slot in numerous pipes or tubes. Discover pipes or tubes in an acceptable grade of steel to comprise the chamber strain of the firing sequence and experiment.
