NORINCO MAK 90 DUST COVER SERIAL
The fact that these bolts are serial numbered is very important because they are not always interchangeable. SKS Stocks, AK47 Stocks, MAK90 Stocks, & AK74 Stocks Work only the rough edges do not try to polish the whole bolt. Both our stamped receiver models needed their rough edges buffed. Inspect your MAK 90 bolt for rough edges and burrs left from machining. The bolt from the Hungarian SA 85M is slotted down both sides and appears to be perfect in every way. All three MAK 90 bolts are well finished and properly hardened but the bolt from the machined receiver is much better. Now push the bolt forward and out of its hole in the carrier. To remove the bolt from the bolt carrier, push the bolt to its rear position in the carrier and rotate it clockwise a quarter-turn. You may need to try it several times to get it just right. Remember, a little bit of pressure goes a long way. If the front lip allows the front of the receiver cover to move up and down, take a pair of needle-nose pliers and flatten out the top curve on the lip of the receiver cover. The same procedure will work on the rear of the receiver. If the front is moving from side to side, then squeeze the front bottom edges of the cover together. If your receiver cover was loose, place it back on the receiver without the internal parts inside and try wiggling it again. With the safety on fire, pull the bolt back as far as it will go and lift it up and out of the receiver.
Now it may be lifted up and pulled straight back for removal. With the receiver cover off, you can push the recoil guide and guide spring forward until it clears the guide bars in the receiver. When it comes loose at the rear, lift it up and pull it back out of the receiver to remove it. Push the guide rod into the receiver cover and hold it there while you pull up on the rear of the receiver cover. The rear of the guide rod sticks through the rear of the receiver cover. Wiggle both the front and rear of the receiver cover to make sure there is no excessive movement. Remove the magazine, check the chamber and dry fire the rifle. Poorly fitting parts can be found in the new rifle, but only time and use will show wear points, spring problems, and slippage. When you work on a MAK 90, keep this in mind if you are trying to replace or change parts.Īs we disassemble the rifle, there are several factors to look for that will make a great deal of difference as we go along.Ī rifle that has had a thousand rounds fired through it is much easier to work on than a nearly new rifle. Many intentional changes, from different springs to varied dimensions of internal parts, were made in the different plants that produced these rifles. While some parts may exchange, the key to working this rifle is recognizing that not all parts will. Some MAK 90 parts will exchange but because the rifle was made strictly for sale to the U.
Designed as a military weapon, it is easily disassembled and worked but not necessarily simple.
