Hello all

I'm a new member of bladeforums. Glad to know that there is such a professional place.

Im looking for complete original drawing with dimensions of the M9 bayonet, to make an accurate 3dmodel based on it. I had a lot of searching on internet, I have TM manual and drawing number, but have not found any drawing at all. Just wondering if anyone have copy of original drawings? I'm also looking for M6 bayonet drawing( Found some but not complete) Any help would be greatly appreciated.

Thanks in advance.
 
Try mocityman, their site has a bunch of M9 info.

If they don't have it, they might be able to help.
 
In the past, I had thought that there could be a niche for a Mil-Spec compliant bayonet from a semi-custom maker made from premium materials, steel, handle etc. For instance, in the early Y2K decsde, I bought a Chris Reeve Green Beret for an active duty marine.Atthe time, it was about as good a "combat" knife as could be made. I thought that it would not be that hard to re-design the handle end to create a bayonet.

I think that Zero Tolerance had one for a while and maybe someone else too (Uzi?).

Today, the Marines have dropped the bayonet and maybe the Army too, so n ow it's a moot point . . .but if you do find the drawings and specs a custom maker could recreate one from high end materials . . .which would bee neat to see.

Suggest doing some research. Some bayonets were discarded from Mil use for "reasons", not least their weight and limited utility.

Generic US Bayo info: https://en.wikipedia.org/wiki/Category:Bayonets_of_the_United_States

Note that the various iterations of the M-4 through M-7 series had different attachments to the rifle. M-5 (Garand) had a lug, while the others had a bayonet ring whose I.D. was matched to the barrel/muzzle device of the rifle for which they were intended. IIRC, it is not possible to interchange these bayonets amongst different models of rifles. I would be extremely reluctant to modify an "Original bayonet, but Repros, possibly of indifferent quality abound, and may be fair game.

Commonly available (and fairly inexpensive) M-7 bayonets for the M-16 platform exist and sometimes can be adapted to the Mini-14/Mini-30 platform (and other platforms) depending on O.D. of accessory/OEM muzzle device vice I.D. of bayonet ring. Depending on the specific model of Mini (or other rifle barrel), may require an add-on bayo lug from Cogburn Arsenal: https://cogburnarsenal.com/shop/

Most add-on Mini-14 bayo lugs preclude add-on "barrel struts" which are highly useful on early "pencil-
barrel Mini-14s. Mini-30 users have originally "heavier" barrels, so likely little/no gains from accessory barrel struts. Later Mini-14 have "heavier" barrels, so also less likely to benefit from barrel struts. I'd rather have the accuracy-enhancing barrel strut than a bayonet, but YMMV.

M-9 bayonets usually downgraded by field users on account of weight. Similar with modern USMC AR bayonets; too damn heavy.

If you want a Bayonet, and if your rifle will/can be made to accept such, strongly suggest the common M-7 bayonet, which is fairly lightweight and makes a "passable" field knife. Bonus points for more modern M-10 scabbard instead of far more expensive and inferior antique M-8 scabbard.

None of these GI bayonets and scabbards are becoming cheaper as time goes on.

Suggest not re-inventing the wheel here.

Folks owning an M1 Garand and/or a 1903 Springfield rifle might search for Korean bayonets which were shortened US M1 model Garand bayonets. About the length of M-7 bayonet, occasionally with carefully crafted metal scabbard. Plan on adding an Alice>Molle adaptor to interface Hooks on bayo scabbards onto modern MOLLE platforms. Modern M-10 scabbard should fit this knife.

As for myself, I use aftermarket A2 style flash suppressor (closed bottom to deter dust signature) on my M1s. Requires the later "plug" M5/M5A1 style of M1 bayonet.

Where did you see the USMC has dropped the OKC Bayonet? John

Best I can do is point you at the patent:

US4821356A - Military bayonet and scabbard - Google Patents

A bayonet and scabbard are capable of being pivotally connected to constitute a wire or metal tape cutting implement having a recess shaped to capture the wire or tape before such cutting begins. The bayonet blade has a tang extending into the bayonet handle which is of a yield strength greater...

Has pictures, but not dimensions.

Thanks Knarfeng, no dimensions but it is still very good information. It is also original.​

I had found this website before, but I have't thought of contacting them. I will try. thanks.
 
Have you tried Bayonet world?

And if you want to recreate it 3D, do you need it to be extremely accurate?

You can check on the AR15 forums, some folks love bayonet.

Fortunately, the M-9 bayonet can be completely dis-assembled, using a hex wrench, into component parts most all of which can be fairly easily dimensioned and printed. Not at all sure how one would "print" a decent blade, though.

This person offers some M-9 parts: https://mocityman.com/m9-bayonet-parts/?sort=featured&page=1 The "EOD" variant is simply an M-9 with a different pommel and guard.

Note this extensive listing of info on the M-9: https://mocityman.com/m9-bayonet-resources/

NOTE: If cutting electrically-charged wire(s) the OEM steel pommel screw will allow the Elec charge to be transferred to the pommel. The guard will also conduct electricity, since it is directly connected to the blade. An appropriately threaded and correct length fiber Allen-head screw can be substituted for the steel unit, thus insulating the pommel. When "stabbing" with the bayonet, the screw is under no stress, however, on "retracting" the bayonet, the screw is placed in tension. I admit to not yet "fully" testing the screw in all respects.

It is unknown if "slashing" with the bayonet along with fiber pommel screw will incur any significant stresses on the fiber screw.

A very thin rubber/plastic insulator glued to the handle side of the guard should protect the user from electric shock from the guard but take care that the insulator is not so thick as to preclude attachment of the bayonet to the rifle.

If all this concern about being "shocked" by an electrified wire/fence seems a "bit much", suggest that aside from being thoroughly unpleasant, being shocked may cause user to make unwanted noise/body motions.

Not yet, it's the first i know this name, I will try

And yes, I want to create a highly accurate 3D model. Try to restore the details as accurately as possible. I still have a lot to learn.

reverse engineering is my last resort, it can only provide limited dimensional information and cannot reveal the specific details of the material and heat treatment. If I obtain the dimensions, I will print some parts and CNC machine some parts machined. And really appreciate for your advice

Have you seen the book M9 bayonet the authorized history? There are some dimensions in the book.

Check bookstores online, ebay probably has a few...
