Swiss K31 Full Disassembly & Clean

[@Jaden48108]

Bought mine 5 years ago and it was in pristine condition. Took it to the range. At 100 yards, open sights, fired three head shots on a mansize target-- could cover all three bullet holes with a quarter. I would go anywhere with this gun, either hunting or defending my mailbox. Simply incredible. Nice tutorial, sir.

[@teddy2guns404]

[@TomMarvoloRiddle01]

Im olmost in tears watching. Im swiss and i have the original K31 that was handed to my grandfather. I love how pretty much everything about this rifle is made with such a quality. Im gona dissasemble mine and deeo clean it. The rifle hasnt been shot for probably 25 years.

[@Toolness1]

When I got my first one a decade ago for like 325 bucks and took it apart, I saw the crazy good design and craftsmanship and knew the rifle was gonna really shoot up in value eventually, even more so than most of the other milsurp rifles that were really good deals at the time. You can just tell when you handle one of these that the work that went into it is really a step above almost anything else from the time period.

[@franzschmid9079]

Hi all, I have several of them in nearly new condition (one from my grand father as well). They shooting mostly sub moa with Swiss Army Ammo 7.5 x 55. The one with the scope, I get even less then 1/2 Moa. Very important the hold it accurate is, don't screw the front band screw on the stock to hard. Most old Swiss snipers they surrounded the barrel with a peace of soft paper and screwed the band very soft so that nearly no pressure occurs the the barrel. You have to know, that the training distance of every Swiss solder was always 300 meters (330 yards) standard distance. And they hit a target of 10 cm (4") with open side (good shooters only). regards from Switzerland

[@jdc3233]

I just inherited a K31. This video, Eric, is so extremely helpful. I can't thank you enough!!

[@anguisnigra]

Just found a K31 locally and picked it up a few days ago. It's in great shape but badly needed a deep clean. This is the first rifle ive ever owned and this video was super helpful for me. Thank you!

[@alexsakon]

I just got one in fantastic shape. Didn’t realize that the barrel was floated. I’ve been amazed at the quality and figment though

[@type_s_tyler7547]

I was looking for my first milsurp rifle last year, you convinced me to get a K31. I picked one up built in 1935 with a brand new stock and bolt. Thing shoots like a dream, and now I actually have the confidence to take her apart and clean it! Just wish GP11 ammo was easier to come by. Thanks Eric!

[@gordonhuskin7337]

so you don't actually have a 1935 K31 then.......

[@zaca952]

The K31s are stocked up like a No4 Enfield with some up pressure at the muzzle to help with barrel harmonics, Do Not remove this contact portion to free float completely, it will reduce accuracy immensely. Unlike the No4 Enfield the K31 also has some down pressure from the upper handguard as well, do not alter this stocking arrangement as it will reduce accuracy

[@alexanderbrown2717]

I also mentioned the shim in the stock, sometimes they get lost.

[@ger808]

i think you will find he already said that in the video :)

[@zaca952]

@Ger Murps he never mentioned the handguard contact nor the misconception of free floating improving accuracy, The stock contact at the forend was to improve accuracy not for bayonet use as mentioned. This somewhat implies that it could be more accurate free floated completely. Your accuracy would actually be significantly worse as the forend stabilizes the lighter barrel

[@remiman7722]

I bought my K 31 about 7 to 8 years ago, serial number in the 7000's & in excellent condition. Some older guy at my local shop showed me one for the first time, and I was in love. It was my first surplus gun I ever owned, I paid less than 300 for it. Its the nicest gun I own, I haven't checked ammo for it in years but I imagine its expensive as hell right now. This video like all your others will help me give it a proper clean up. Thanks for all you do, you're a top Chanel where on KZbin, and im not talking about just in the gun community. All together.

[@matthewcarlson5505]

12:08. I actually did some calculations on the cost in 1942 to replace the rifle. In 1942, 42 Swiss Francs was about equal to $47.04 USD. And so, calculating for inflation, $47.04 USD in 1942 is the equivalent for about $900.73 USD in 2023. So, the cost to replace a K31 in 1942 was around the cost of $900.73 USD today.

[@bhoward9378]

What about production costs? We are all being robbed by those responsible for inflation.

[@matthewcarlson5505]

@@bhoward9378 Oh yeah. Well, if it COSTS the company around $900.73 to MAKE it, then the end price to the consumer means that it costs somewhere around $3k or somewhere in that ballpark to purchase it today.

[@radieschen79]

I have one of these K31 from my grandfather who served as a radio operator (Funker) during WW2 in the Swiss army, wonder if the old dame is still functional. Nice detail I didn't know about was the troop tag underneath the butt plate, I disassembled it and there it was. 😄 In the handwriting of my gramps... Thanks for letting me know! Edit: He was a trained toolmaker in every day life and would have loved watching your videos.

[@cameronmccreary4758]

The Swiss treated their soldiers with respect. Just look at the quality of the personal arms issued to the soldiers. The Swiss government cared that each soldier was given the opportunity to come back home when an operation was completed. I looked up the pliers and they are box joint made by Friedrich Dick sold by Brownells. They are box joint so the tool doesn't side twist and damage the part being held.

[@elrondmcbong467]

The K31 is still a very popular rifle among sport shooters in Switzerland and in Switzerland it is usually shot at 300m/328 yards. The Swiss Army's requirements for the K31 at the time were that it should be as precise or more precise than the IG11 which is 131cm/4.3feet long but not much longer than the K11 which was 110cm/3.6feet long. Of course, the Waffenfabrik Bern didn't settle for just as good and actually managed to improve the precision of the K31 over that of the IG11 and still have the same length as the K11. Some even say that winchester took "inspiration" from the GP11 to make the .308 because of the oddly similar dimensions and performance. P.S. There's always the rumour, that the GP11 is out of production. This isn't true. True is that RUAG, the producer of the GP11, temporarily stopped production a few years ago due to quality issues but after those were resolved they started production again and this until today. However there are other manufacturers that makes 7.5x55 Swiss which technically is GP11 but because GP11 is the military designation for 7.5x55 Swiss, there's only RUAG that can legally call it's ammo GP11 because they do all the ammo for the swiss army.

Sir great day to you and your team and loved ones !, Sir what a great job you and your production team have made with your educational Video , I very much hope you don't mind that I'm about to mention, just a couple things regarding you and what you have said !! like i was saying its about what you have already mentioned many many times in this production, that been the word( precision ) Sir , with the incredible making of this K31 Rifle . I totally agree with you all day long at that, but really !! does this really surprise you or anyone else viewing this over there precision quality! after all its the amazing Swiss gun smiths & engineers were talking about here, that Name or Word alone speaks for itself( Swiss or Swiss Made )!, they are renowned for precision with the build quality in everything and anything they make in a mechanical aspect ..... for example look at there watches the Swiss are known for there is no other in the world that can match there overall sheer precision and quality in the internals of these watches and that's where it all counts in the end of the day !, anyone can make a watch look pretty but its the sheer precision & accuracy of that time piece that means the world to the owner, if you ask me its the same regarding this magnificent & simple, but beautiful and elegant rifle the engineering that was put into the development of the workings of this rifle is second to none Esp been built in a time that everything war related was rushed through by everyone else in this industry at that time, but the Swiss said no we will build these rifles to perfection, as if there was indeed no war on, so the reliability and quality and precision will all remain at the top and if not next level to every other manufacturer of those time's...The incredible Swiss have ultimate pride in production so I'm not at all surprised ever!!!! Good day to you sir and your team , and hope yall have a great christmas to come 2022, but more importantly may yall have an excellent new year to follow . I wish this also to anyone reading this crazy comment of mine

[@thecanadianlanboy8132]

Like a No.4 or 1903 up pressure near the end of the barrel is crucial for accuracy. This was not done for bayonet security. DO NOT FLOAT A K31 - Accuracy will go out the window

Eric please make a video of you deer hunting with a military surplus rifle

[@Foche_T._Schitt]

Yes remove the follower and spring from your magazine and clean it. I've seen too many neglected magazines. Just remember the orientation. The acids from the wood can fade the writing or the butt plate can stain the troop tag, sandwich it between some archiving plastic like a BCW protective page. It's not unusual for the sling clip to be missing from the sling, they made noise. Soldiers don't like noise. Removal of the sling ferrule may result in wood chipping out of the buttstock. It's not a full floated barrel when assembled. You missed pointing out the shim under the receiver in the stock.They come in different thicknesses and are selected by the arsenal to tip the barrel up so the upper hand guard can bear down on the barrel to dampen the harmonics. *DON'T LOSE THE SHIM* The front receiver screw should be tight. The rear should snugged down drawn up until it starts holding a group. German 101, whenever you see a W pronounce it like a V. Like LuftVvaffe. Vvaffenfabrik.

It is very unfortunate there is no aftermarket ammunition with the same bullet dimensions as what the rifle was designed to eat. All of the PMC (edit *PPU) stuff uses generic dimensions. Take a set of calipers and pull a bullet from a swiss military surplus round and take some measurements compared to that of the PMC (edit *PPU). The dimensions are very different. Make sure to measure the diameter at a couple of different locations along the surplus. It was designed not to be congruent. The PMC (edit *PPU) is consistent and oversized throughout its diameter. The pressure curve and ballistics are going to be very different. The throat and barrel wear are going to be very different (excessive). The accuracy is very different.

Switzerland started producing GP11 again for their machine guns and competitions but I doubt any of it will trickle to the states anytime soon if at all unless you have connections. Militaries usually surplus their ammunition after 25 years. After 50 years the powder is breaking down and it gets hotter which is why everyone says Turk mauser ammo is hot. Because it was freak'n old and stored in awful conditions.
