Contest Entry: Get Your Mosin Bayonet to Fit Perfectly in Less Than 10 Seconds


By Collin Buckles

Buying a Mosin-Nagant is a very exciting experience. However, finding out that your bayonet does not fit your rifle can put a slight damper on the celebration. Here are some very simple steps to get your bayonet to fit perfectly in less than 10 seconds without any power tools.

Supplies needed:
1. Shop rag
2. Any sort of hammer
3. A sturdy metal corner (such as the base of a bench vice) . . .

Step 1: Holding the bayonet by the blade place the open end of the cylinder at the base of the bayonet around the edge of your sturdy metal corner as seen in the picture below.

Step 2: Place your shop rag over the base of the bayonet to prevent any scratching.
Step 3: Lightly but firmly hit the cylindrical base of the bayonet with the hammer. Center your strikes as much as possible to the corner so that the bayonet opens up evenly.


Step 4:
Every few strikes check how the bayonet fits in your rifle.

If you open up your bayonet too far and it fits loosely on the rifle, do not worry. The bayonets seem rather ductile and are very forgiving. Simply lay the base of the bayonet on a flat surface and hammer it closed until it fits correctly as shown in the picture below.


Finally, now that you have your bayonet properly fit onto your Mosin-Nagant, it will most likely shoot much more accurately when using iron sights. Just a warning though; you may also find yourself stabbing cardboard boxes in your backyard because a bayonet is not simply attached to a rifle and ignored. Enjoy!

    I’ve owned my Moisen for over 25 years, and NOW I want a bayonet. What kind of ball park dollar figure do they cost in generic useful condition?

    1. avatar Joe R. says:

      That’s how it starts, you want a bayonet, then you want an Archangel Stock with 5 and 10 round mags, a comp trigger, a bipod, some long-range optics, 2000 rounds of surplus ammo, 500 rounds of soft-tip hunting ammo. . .

      But, the rifle is only $129.00.

      1. avatar Chicago Steve says:

        I have the boyd’s tacti-cool stock and really like it for mine.

        So no detachable mag, but the only decent rifle range in driving distance of northern IL is single load only. (darn you wisconsonites!)

    2. avatar Stinkeye says:

      A decent 91/30 bayonet will cost you about $20-$30.

      1. avatar bontai Joe says:

        I only paid $35 for the rifle back in the 1980’s. But in today’s dollars, $30 seems like a pretty good deal.

  2. avatar Defens says:

    Pretty cool! It would appear that Mr. Buckles may have apprenticed at the Century Arms College of Gunsmithing. 🙂

    Seriously though – articles on little gunsmithing projects are fun to read, and helpful for folks who get all flustered at the sight of a screwdriver. Nice job and good on you for writing it up.

    “What is the spirit of the bayonet?”

    “To KILL, KILL, KILL cardboard boxes!”

  4. avatar PeterK says:

    I actually had to sand mine out a little. I did try a similar trick, though. It’s fun with that bayo mounted.

    Just don’t ask me about the time I stuck it in the roof getting it off. Yeah. (that was before I fitted it. :p)

    1. avatar ShaunL. says:

      I have 2 holes in the ceiling from trying to put one back on the rack without taking off the bayo.

      1. avatar fiundagner says:

        only 2?

  5. avatar ShaunL. says:

    You may also clothesline yourself with the sling while walking through the nearest door. When you sling a 91/30 with a bayo on your shoulder you become MUCH taller than you remember….. Trust me.

  6. avatar Swarf says:

    Best Mosin trick I’ve figured out is to clean the area where the bullet seats with a shotgun brush soaked in mineral spirits attached to a cordless drill.

    Most people’s problem with stuck cases stem from not being able to get all the gunk out of the chamber. This includes lacquer that heats up with firing the hardens back up, resulting in the reason you take a hunk of 2×4 to the range. This fixes that.

    I used a 12ga bore mop, but that was a little too tight. 16ga might be better.

    1. avatar JWM says:

      If memory serves I used a brass 20 ga brush on my sticky chamber.

  7. avatar JWM says:

    First thing I noticed when I was young and studying up on ww2. Russian soldiers didn’t appear to have scabbards for their bayonets and the bayonet was always fixed to the rifle. Turns out there’s a reason for that. Unfixing a 91/30 bayonet can be a dangerous pain in the as*.

    I only have one 91/30 left. It’s bayonet is in my garage and I’ve never even attempted to fix it. Some things are just too broke to fix.

    The m44, however, has a bayonet system that, at least in my experience, works like a charm. Some of my m44’s, of which I have given all away, shot better with the bayo extended. Some not. Each had it’s own personal;ity.

    1. avatar Art out West says:

      I’ve also got the M44 with the side folding bayonet. Mine shoots better with the bayonet extended. I think the under folding bayonet on the SKS is even better.

    2. avatar C says:

      The sights were zeroed with fixed/extended bayonet.

  8. avatar C says:

    My bayonet was also tight on the barrel. I finally got it fit only to discover that the the sight post channel is about a quarter inch too shallow for the thing to turn and lock. So it will turn, but not far enough for the lock to engage. It’s my understanding that the bayonet was fit to a specific rifle at the time of manufacture. That’s why virtually none of them fit right out of the box.

    People actually spend this much time and energy on a Mosin? Well, God bless ’em, I guess it’s more fun than hammering on rusty rebar or old drive shafts.

    1. avatar Swarf says:

      Don’t be disrespecting Mosins.

      I could use mine as a driveshaft in a pinch. Try that with your Tinker Toy AR.

    2. avatar bontai Joe says:

      “People actually spend this much time and energy on a Mosin? Well, God bless ’em, I guess it’s more fun than hammering on rusty rebar or old drive shafts.”

      I own several pretty rifles, many wood stocked shiny blued pieces of art and a couple of old battle scarred military rifles, one of which is a Mosin. It’s much better than an equal length of rebar, because it can easily shoot 300 yards with inexpensive ammo. And when necessary, it CAN be used as a tent pole, a boat paddle, as exercise equipment and as the comforting object I hold while sleeping, that keeps the boogey man away. I don’t love my Mosin more than my other rifles, but I respect what it is and wouldn’t hesitate to grab it if I needed it.

    I’d like an article on adding a ‘thing that goes up’. The bayonet isn’t intimidating enough.

    1. avatar JWM says:

      In all honesty the bayonet is just an over sized screw driver. The 91/30 with bayonet should be in the record books as the worlds longest and heaviest screwdriver.

  11. avatar Clem says:

    Instructions unclear. Penis caught in ceiling fan.

    1. avatar JWM says:

      I had a similer problem til I learned to sleep on my stomach and wear briefs to bed.

  12. A recoil buttpad is an accessory you add to your rifle to take the sting out of those shots from your high-powered Mosin-Nagant.
