I see Cogburn Arsenal has 2 piece clamp on bayonet attachments that should fit a Mini-14. Bayonet Lugs – Cogburn Arsenal

The question is, they have them for M-14, M-16, and AK bayonets, which one would best fit a 582 Ranch rifle barrel?

Also, what is the diameter of that barrel?

Thanks!

580 and up series barrel = .625". Ranch rifle with clamp on bayonet lug is a terrible idea as you don't have sufficient space/width in the front to seat bayonet properly unless you move the front sight. Too much work & $$$ and not giving you much benefit of actually using one.

Thanks for the info, what you say makes perfect sense.

Just an idea I was tossing around in my head, the practicality is probably nil. lol

a bit off topic but here goes anyway. Cogburn made a lug for my Swiss bayonet - STGW? - that is a one piece requiring front sight removal which fit my 189 series Mini 30 barrel perfect. I have a no longer made Eagle brake-flash hider with the H-K style front sight incorporated which is a tight slide on fit to the bayonet bolster (not sure correct term) mounted. this is a sturdy mount for an item I'm doubtful I'll ever have to wield in a fight. it's mostly a conversation starter I admit, but sure looks impressive.
Cogburn seems to make fine products. I recommend.

Good products, but he's not so hot on replying to e-mails, unfortunately. Must be extremely busy.

If you want to go to the trouble and expense, probably the least hassle is to dismount current front sight, and substitute a Choate flash suppressor/front sight unit: Mini 14 (580 Series) Cage S.S. for barrel diameter of .625 – Choate Machine & Tool – Choate Store Home

Then add approprite rear bayo lug for M-7 (M-16) bayonet, which is by far the least expensive of the US bayonets, and almost identical to the other ones mentioned. Get a less expensive M-10 scabbard for the bayo.

DO shop around.


In the unlikely, but possible event you ever mount an under-barrel strut to your Mini, the bayo lug will need to be removed in most cases.

Check state and local laws as some do not allow bayonet mounts.

to clarify my post #4 the Cogburn lug required removing the front sight to slip the lug down the barrel to the correct spot, where the clamp is tightened to secure the lug.
the bolster ring may be known as 'muzzle ring' to some.

It’s your rifle but why?
It's better to have it and not need it than to need it and not have it.


I like the gb style front sight from cogburn it will shorten your sight radius but give you more room for the front bayonet ring.

I don't actually have that sight, we can't have bayonet lugs in my state.

I’ll agree that a knife is always loaded and I love the bayonets that go on my ‘03s, Krags, garand, M12 and 97 trench guns but not on a sporting rifle. Too many episodes of Walking Dead?

Well, I do have a SKS with a spike bayonet, so I guess that takes care of my bayonet needs.

That's quite a different one in your picture, what rifle is that affixed to?

That is a Krag Bowie that was designed as a combination trenching tool and bayonet. Its on my real deal 1899 Constabulary-school rifle. It proved too fragile and did not pass field trials. Surviving Krag Bowies run $4-5000.00 which is why I built mine. I made it from a 1917 Bolo knife that was missing it’s guard and grips and a rough Krag bayonet. As valuable as they are they are often faked. I’ve only seen one in the flesh and wasn't sure that it wasn’t a fake. The tell is the scabbard, there’s no faking it. A beautiful hunk of steel.

If you have a Ranch Rifle without a muzzle device the only options (beyond having the barrel threaded by a gunsmith) is to buy a John Masen pin on combination flash hider & muzzle brake to add the correct length/diameter to the end of the barrel(or if in a non-AWB state the Choate pin on flash hider which requires drilling new roll pin keyways on the bottom of the barrel). In an AWB state (while also staying under the feature limit), you'll have to cut off the flash hider portion of the John Masen brake and re-blue the end. 580+ series is a .625" OD barrel for the clamp on lug. M7, M9, and OKC-3S bayonets will fit the lug and the muzzle rings will fit over the John Masen brakes/Ruger standard flash hiders. Below is a John Masen pin on combination flasher & muzzle brake with the flash hider sawn off and re-blued as described for AWB compliance.
