The barrels of milled receiver MAK-90 and 91 rifles are not threaded. The post ban models MAK-90,MAK-91,AK Hunter and Poly Tech Legend pre bans have the 386 in a oval. All the milled receiver Chinese rifles have 386 in a oval. The chamber is the largest diameter then steps down at the rear sight block, next the gas block, and finally the smallest diameter is at the front sight.Īll Poly Tech AKs have an oval 386 stamped on the receiver. 584".Īll AK's have barrels that are 4 different diameters in different places. 580" diameter barrels and Romanian's are. 684" diameter barrel and the NHM-91 has a. I took some measurements: All measurements were taken with calipers and the barrels were measured 1/2 way between the front sight and gas block. (I cleaned up the grammar a little bit, for clarity):Īll Chinese AK rifles have barrels that are larger in diameter than European AK's. "JA" posted the following remarks on the Gunsnet Forum in 1999-2000. Original model name ground off, and re-stamped MAK-90 Sporter They were named "Sporter," and sold with a five-round magazine, to make them seem more like hunting rifles.
NORINCO MAK 90 THUMBHOLE SERIAL NUMBER
Some had 90 added to the serial number that denoted the year of import (1990). The model name was ground off (or lined through) and the new model name MAK-90 was stamped. What appears to be threads are just machine tool marks.
If your entire barrel on your MAK-90 seems to be threaded, then it is NOT. The LH means that the threads are left hand and to screw a muzzle brake onto the barrel you will have to turn it to the left/counter clockwise." I think a lot of MAK-90 owners think they have a threaded muzzle when they really don't. This means the diameter of the threads is 14mm and the pitch is 1mm. According to "J.A.," ".The standard thread size for AK-47 type rifles is 14x1mmLH. The bayonet lug was ground down to eliminate the possibility of the MAK-90 having an "evil" bayonet. In 1990 the Chinese AK factories screwed a nut on the muzzle to cover the threads, and some were tack welded on. Standard WASR-10 As Modified and Sold by Century International Arms (In contrast to the MAK-90, you may note that the WASR-10 has stocks of cheap plywood, a ribbed receiver cover, open-top sights, no "dimple" in the receiver, and a Soviet-style scope-mount welded on the left side of the receiver.) Century International Arms takes the WASR-10 imports from Romania, reams out the magazine hole to accomodate a double-stack 30 round standard magazine, and then replaces enough parts in the WASR-10 to make it 922r compliant.
The WASR-10 is based on a CUGIR Romanian model, but is modified to be "922r compliant" and distributed in the USA by Century Interational Arms.) On April 6,1998 a ruling by the Treasury Secretary banned the import of semi-automatic rifles that use a magazine holding more then ten rounds. (I would venture to opine that the most common model NOW (2009) for sale in the USA is the WASR-10, modified for 30-round magazines. They often were sold with three 5-round magazines, an oil bottle, a cleaning kit and a sling. The retail price for a new MAK-90s was often less than $200. A very few were made to shoot 5.45 x 39 ammo. According to "JA," of, more MAK-90 rifles were imported from China than any other model of semi automatic AK type rifle from any other country. Around a million MAK-90s were exported to the USA in the early 90s. (The earlier AKs were banned because of their "evil" features: pistol grips, folding stocks, threaded muzzles and bayonets.) The new model was basically an AK with a wood thumb-hole stock and no bayonet lug (although you do sometimes see MAK-90 receivers with under-folder holes drilled and filled). Following the import ban in 1989, the Chinese developed an AK which met the "sporting purposes" clause. The MAK-90 is a Chinese factory built AK model exported to the USA from China from 1990 through 1994 by two Chinese export companies: Norinco and PolyTech.
I have owned three of them, and share some of my photos in this web page. The letters/numbers MAK-90 stand for Modified AK-1990. Receiver metal thickness: 1.6mm (most other stamped AKs have 1mm thick receivers)
