AR guy with AK problems

[MikeSmith]

So i bought my first AK about a year ago and just now trying to fix the problem i had when shooting it for the first time. It's made from a 1960s Polish AK47 parts kit i bought from armsofamerica and it was put together with an NDS-1 Nodak Spud receiver. This was the preformed receiver that needed minimal work.

Problem#1: When pulling the bolt back it seems to hangup on the hammer. When i test fired the gun it doesn't cycle properly because of it. This is the original Polish trigger group.

Problem#2: When trying to remove the safety lever to replace the original trigger group the safety lever won't rotate all the way up because it hits on the sear. I bought a tapco G2 single hook trigger to replace but I'm now unsure if this is going to solve my problems.

Pic#1 is showing how the safety lever hits the sear.
Pic#2 is showing how the original trigger hammer has been hitting the bolt and the new tapco trigger hammer has a taper built in.

What problems did you have while shooting it? Does the bolt hang up on the bolt only while manually operating it? If so I'd Lightly grease the bolt and hammer and shoot it.

Problem#2: When trying to remove the safety lever to replace the original trigger group the safety lever won't rotate all the way up because it hits on the sear.

Your semi-auto AK does not have a sear.
Your semi-auto AK has a trigger, a hammer and a disconnector.



It is NORMAL for the unmodified selector to hit the disconnector.
That is a full-auto selector.
A full auto AK uses the selector to hold the tail of the disconnector down when in the full auto mode.
Then, the auto-sear releases the hammer after the bolt locks up and the carrier is fully forward.

When you convert the gun to semi-auto-only, you lose the auto sear and typically modify the selector to get rid of the part that holds the disconnector down.
That makes it possible to rotate the selector into and out of the rifle without first removing the trigger pin and disconnector.



Your rifle was probably assembled by rotating the selector the other way, or by installing the selector before the disconnector.

The fix is to trim your auto selector to be like a semi-auto selector.

Let the disconnector go back down, then turn the safety lever and it will push it back enough to slide over it. Right now it's to high up so it just hitting it straight on.

Will prevent the safety for rotating when to high up

Everything in position it slides over it http://prnt.sc/c5pid2

Everything in position it slides over it

Did you even notice how the selector has been clearanced in your picture to let that happen?

Thanks Randall that is good info. I did rotate the safety down and around the buttstock and was able to get it off that way. Now is the full auto safety ok to use in a semi-auto gun?

The OP is not running a modified selector like you are.
Therefore, your advice is not going to apply to his situation.

Now is the full auto safety ok to use in a semi-auto gun?

Yes.
It's just more hassle to remove and install.
If you have a bench grinder, angle grinder or even a dremel with a cutoff wheel, it takes all of a minute or two to clearance your selector a little to make room for it to install/remove the "easy" direction.

See the pictures above for how the selector differs from yours.

As far as problem one, how does the top of the hammer looking after riding the bolt across it?

I would call AR15 Barrels, and see if he can help you out.

Thanks for the tips everyone. Tapco trigger is installed. Although I'm not sure why everyone raves about this trigger. It feels exactly the same as my Polish trigger. Long single action pull except super gritty feeling. I actually like my original Polish trigger better it was long but smooth. Anyways I'll have to test fire it to see if it cycles now. It still feels like the bolt hangs up on the hammer a bit. I'll try some grease and test fire it. If that doesn't work i guess a file will do the job.

If that doesn't work i guess a file will do the job.

Don't file the hammer.
If you file enough off to eliminate the bump when the carrier goes over the hammer, you will have a problem with the hammer following the carrier.
The carrier MUST push the hammer down as it slides over the hammer in order for the disconnector to get ahold of the hammer.
