Reader Questions: 6.5×55 Chamber, M47 Clips, Side-Mounted Oprods

Today I’m answering some questions sent in last week – I think this will be a fun and interesting regular feature for the site. If you have a question you’ve been wondering about, please email it to me, and I’ll see if I can get you an answer for the next Reader Questions column! I [...]

Prototype Clausius Model 1905?

A few weeks ago, I wrote a post about a series of pistols designed by a German inventor named Claus Claudius, which began with a long-recoil design in 1895. He then progressed to a floating chamber design in 1900, and finally a fairly conventional short-recoil design in 1905. We found a book with photos of [...]

The Husqvarna M 40 Pistol

Today we have a guest post by Peter Rasmussen on some of the history of the Husqvarna M40 pistol, also commonly called the Lahti. We will cover the mechanical aspects of the pistol in a later post, but this information from Peter is an excellent overview of the different markings found on different batches of [...]

Swedish Army Documents

Thanks to Carolus L., we have a batch of Swedish military manuals for you today. We always enjoy getting international mail, and the package from Carolus was no exception. The most interesting piece of material was a 1951 general manual covering all type of material from bicycles and gas masks to flame throwers and machine [...]

Swedish FM59 Ljungman

In the midst of World War II, the Swedish government adopted the AG-42 Ljungman self-loading rifle, which was chambered for their standard 6.5x55mm cartridge. It was issued to supplement squad firepower, and proved to be an accurate and reliable weapon. In 1965, it and the M96 Swedish Mausers were replaced by the AK4 rifle (an [...]

Direct Gas Impingement Video

Many people already know everything I’m going to say in today’s video, but I think it’s important to get it out there for the folks who don’t have as much mechanical experience with their rifles. Specifically, today we’re looking at how the AR uses direct gas impingement to operate, and how it’s different from the [...]

Ljungman AG42B Video

Being right in the depths of winter, it seemed like a good time to take a Scandinavian rifle out to the range. Specifically, a Swedish Ljungman AG-42B. This is one of the few semiauto military rifles chambered for a full-power cartridge lighter than the 7.62 NATO (the other common one being the FN49 in 7×57), [...]

Mystery Swede

We found these photos of a Swedish semiauto conversion, and have no information on the design. Have you seen this rifle?

Any insights? The only reason we’re even saying it’s Swedish is the “Stockholms Vapenfabrik” inscription on the receiver. The rear sight is a Lange type like on a Gewehr [...]

Flapper Locking video

By request, today we’re going to look at one of the less common locking systems used in firearms design: flapper locking. The idea was first patented by a Swede named Friberg in 1870, but a practical gun was not built on the design until the 1907 Kjellman. The most extensive use of the system was [...]

Snabb Semiauto Conversion

A reader named Roy sent us a link to a very interesting system for converting bolt action rifles to semiauto function. One of them was sold back in 2009 at auction, and (interestingly) the exact same gun is coming up for sale again in a couple weeks at Rock Island.

Snabb conversion of a [...]
