Unbreakable Posted April 7, 2008 Share Posted April 7, 2008 Ok all, I have an older HK M1S90. I want to give it a complete cleaning and maybe even replace the recoil spring as the weapon has about 1,000 rounds through it. But I can't for the life of me figure out how to get this recoil assembly apart. It's completely round and does have anything resembling a nut. I mean there was a 13mm nut that held the stock on... but the recoil tube is round and smooth. I assume I'll have to heat it up to break it loose. But what part do I heat up and with how much heat will hurt the metal? How do I turn it once I've heated it up? I appreciate any info or detailed pics on this.
