Default AK muzzle device washer.

As usual necessity is the mother of invention of sorts for cheap skates .

I needed a muzzle device washer for my rifle and thought to try a spark plug washer. Once the small thread bumps are ground away it is almost a perfect match for the 14 -1 mm LH muzzle.

If you do a small cut for the muzzle device lock plunger it fits great and it is a compression washer to top it off.

Hope this help some cheap skates out there.

What'd you do with the spark plug? Make it pseudo-tazer at the end of the bayonet?

Oh I see. Generally just as easy to use a file to relieve a bit of material off the rear of the brake so it indexes and is snug when it hits the plunger detent. No washer needed. But whatever works.

LOL, yea I know. It just so happen this one application in particular needed a lot of filing just to get to the point of indexing .

The other day I was installing one of this on my new 54r Vepr http://shop.grizzlygunworks.com/prod...&categoryId=17

It required to grind down a washer to custom thickness for proper indexing. Why, because the face of the muzzle device is receded, so it had to have a washer.

The idea of the washer is to make it easier or better say an alternative. If you can get it there with a little filing great, but if the washer gets you there then cool.

I use high-temp silicone o-rings, myself.


Thanks for the tip about the washer

Do you find these at your local hardware store? I found some small c-rings at my local lowe's hardware store and they fit perfect.

I had some brake wobble myself and instead of filing i used the c-ring washers and fits and work's great.

No you will not, if you do your own tune up on your car they usually get thrown away with the old spark plugs.

That's another good idea with the C-rings.

Depending on the brand of plugs they may variate in size

Sparkplug washer 2

Here is one installed in a project of mine.

Sparkplug washer 3

Depending on the initial cut on the threads on the barrel muzzle, the spark plug washer may just fit right in with no grinding of the inside diameter stubs. A dremel will work rally good on this for a good fit and the lock plunger cut.

That appears to be a neutered AK74 FSB with no plunger. You can add a plunger buy using one with the cutout like in a AKM and drill a smll retaining hole in the FSB just behind the small swell in the block to hold the plunger. No need for a washer to hold the brake in place etc.

Just an FYI. I did it on a Khyber Pass build.>
