I'm new here and found nothing on this subject by searching... so sorry if it's been covered.
I'm thinking about changing the barrel on my NHM-91 to a MAK-90 barrel. The NHM is too long.
It looks as if the barrel / upper reciever assembly is held in place with three pins that have peened heads on both (?) sides of the receiver. I assume that the heads will have to be chopped off to remove the current barrel... is this the case?
Also, is it possible to change the pins from the peened to a friction fit pin such as the AR rifles use? If not where can I get some of the standard pins?
Any other considerations to making the change? All comments and suggestions would be greatly appreciated!
By the way, I have a MAK-90 parts kit which has the barrel / upper, gas piston / bolt carrier and bolt.
Thanks & Happy Shooting!
