Newbie Question

[Antonrx]

Hey all. I just picked up my first AK variant... MAK 90 underfolder... It shot well and other than a little sight adjustment, it's awesome! The only thing is I can't figure out what year it is? I've read that the serial number will have a prefix stating the year but mine doesn't (0079xx)... It has a threaded barrel end; which I've heard is more sought after... It doesn't have the double hook trigger though? Only single hook? Looks like a Tapco handle too. On the left side at the back it says:

MAK 90
7.62 X 39 MM
Made in China
By Norinco

Sorry for the long description. How do you post pics?

Thanx

Welcome to the board Antonrx.
Welcome to your new AK addiction.

Imanaknut here is the resident expert on Chinese AKs. I'm sure he will be seeing this shortly. He more than likely will have the info you seek.

I opened an account (free) at Photobucket.. www.photobucket.com and upload my pics there to post here. If you decide to go the Photobucket route, and have a problem, just post back here and we'll help you out.

[Antonrx]

Thanx buddy... I'll post some pics once I set up the photobucket account.

[Antonrx]

[slamfire51]

I fixed for you.

[slamfire51]

Hey, that's a nice Mak.
I like.

Go back to Photobucket, click on a pic in your album.
There is a box to the right of the pic.
Left click on IMG code. It will turn yellow and say, "COPIED".

Now go to where you want to post it and right click and click paste.
That's all there is to it.

I did exactly as I described below.

Give it another try.

Welcome to the group, and the AK-addiction !!!

When the MAK-90 came into being thanks to George Bush the First being afraid of bayo lugs, flash hiders, and pistol grips, some of the ones caught in port during the first days of the ban were allowed in with only minor modifications.

Some underfolders just had the famous Bush-hole stock installed over the folded folder with a tang welded on for the stock screw. Most had the folder removed and a rivet holding plates in place was intalled to cover the folder holes before the Bush-hole stock was installed.

Many had a muzzle nut tack welded to the front sight, with the cleaning rod holder still intact but the ears of the bay lug on the gas block ground off.

Yours was just after that with the cleaning rod holders completely ground off because ATF found that an evil bayonet could be clamped onto the front sight cleaning rod holder.

I would guess that your rifle was one with the riveted folder holes. Someone cut the rivet, and installed the folding stock, ground off the tack welds and installed the muzzle brake. Then because of another really stupid rule, originally known as 922(r), the owner removed that great Chinese fire control group and installed the Tapco parts so that the rifle didn't have more than 10 imported parts, per the stupid imported parts rule/sporting purpose clause of the ATF version of the second amendment.

Clear as mud?

Anyway, the only MAK-90s with dated serial numbers were the 1993 and 1994. Rumors of a few with "92" are floating around but I have never seen one. Yours most likely is an late 1990 based on the fact that it doesn't say "MAK-90 Sporter" and was still with the threaded barrel but without the cleaning rod holders.

Regardless of all the stupidity of 922(r), now Title 277 CFR 478.39, and the stupidity of anti-firearm George Bush the First, the MAK-90 maintained the desirable shooting qualities of the early Norinco 56S, just in baby loving angelic form.

Enjoy your rifle, one of the nicer post-bans floating around. I just happen to have a Chinese folding stock just waiting to be installed on a MAK-90 or NHM90 with the receiver set up for the folder, but in full "Bush-gear".

Next time polish your toenails

Welcome nice rifle

[Antonrx]

thanx guys... I appreciate the info! Do you think I should swap out the single trigger for the double tapco trigger? I've done some research so I realize the double trigger is suposed to be more smooth and the fact that the receiver has the cut out for a double makes me feel like I should change it... What you all think?

[imanaknut]

I wouldn't change the trigger unless you don't like the feel.

Someone was worried about your feet, yet failed to mention that the slant brake on your MAK-90 is upside down. There should be a detent pin in the front sight base. That pin fits into a slot in the brake to align it correctly. The brake aids on a real-deal AKM that in full auto climbs up and left. On a semi-auto it is not as noticeable, but should still direct the gases up and left helping push the muzzle down and right.

[Full Otto]

Not worried just trying to be helpful

While your here and I'm guessing it's been asked before.
In regards to the front site block
Is that solid in those without the hole or is there room in there for the spring and detent pin if you drilled the hole for it through the front?

[romak10/63UF]

If you have ever tooking out your fire control group it can be a pain in the ass to get back in... if you have experiance in doing this yes i would tell you to go back an get the right trigger groud for your mac-90.... i personally owend a MAC-90 milled reciver ak-47 hands down that was the best ak-47 i ever had the double hook trigger give you 100% better feel over the rifle when shooting it... This is my thoughts... coming from some one who have owned over 5 differant types of ak-47s in my life time... Im sure the old timers would agree the double hook trigger is smoother than the single hook.

By the way nice rifle.... ! A + deal !

[imanaknut]

I did drill out a sight block to install the retaining pin and it was unfortunately solid.

I'm glad you mentioned that... I noticed a slot in the break that lines up with a hole in the base of the front site but there is no pin to keep it there... What's the best way to fix this?

[imanaknut]

The front cross pin in the sight block holds the locking pin in place. These are the parts you need:

The cross pin is sometimes a bear to drive out. I lay the rifle on my garage floor with a scrap of carpet protecting the rifle itself. Lay the front sight on a 2x4 scrap with a hole drilled in it to catch the cross pin. I use a punch holder so that I can get a good hit on the punch with a heavy hammer or steel mallet. That way I don't have to worry about fingers or a hand getting in the way of an errant hammer blow.

Once you have the cross pin out, clean out the locking pin hole hole, which over the years might have picked up some dirt or a bit of rust. Then install the spring and slide in the locking pin itself, small end first (obviously) and make sure the slot is pointing down so that the cross pin goes under the locking pin. I usually start the cross pin first, just enough so that I can still get the spring and locking pin in. Then lightly tap it into place, with each hammer hit making sure that the locking pin moves freely. You don't need the punch at this time, so you can hold the plunger pin in with one hand and tap the cross pin with the other. It is very easy to have the locking pin slightly sideways and the cross pin will cause it to bind and not allow the cross pin to go in all the way. Once the cross pin is in enough to keep the plunger pin in, and it moves freely, then you can us the punch to fully seat the cross pin.

The reason I say use a garage floor, or other concrete floor is that a work bench regardless as to how sturdy it appears, will have some flex which is just enough to absorb some of the impact of the hammer on the punch, which doesn't allow the full blow to be transmitted to the cross pin.
