I recently acquired an HK imported M1 Super 90 package. It came with a PG stock, straight stock, 20” barrel, 26” barrel, and optic mount. The proof mark on the 26” barrel is AS, which as I understand dates it to 1987. It has several upgrades, a GG&G magazine follower, oversized safety, and anti walk pin, optic mount, etc. Also has Velcro on the left side of the receiver and came with 3 shell cards. (Not sure I am gonna keep that in place). It was sold as LE Package, and the original paperwork verified that. Not sure if it was a Benelli, HK, or LGS package. The seller got it from a local retired LEO.
I have been trying to locate choke tubes, as I understand they are the 2nd gen tubes, not Mobil or Crio tubes. Any ideas on where to find them?
Wondering about the optic mount….I have read adding weight can affect reliable cycling. I plan on adding a small mag tube rail to mount my light, but don’t want to add too much weight
Would removing the Velcro by soaking it in Goof Off or Goo Gone and carefully using a plastic scraper be a good idea?
Thanks for any info
