I should have one for my MP5 in the next 4-6 weeks. Can't wait!
If you drill a recessed hole on the side where the threads come out,you can use the regular push pin instead. I have already done it bro. You have to drill a little bit at a time until the slittle spring clip locks in. Easy as pie."Nutnfancy" on youtube just posted a booth review with Troy. They show the HK rails right at the end of the video just for a bit. They said they'll give a 10% discount with code "nutnancy" on the Troy website. I'm looking at the handguard for my PTR 91 GI. I like that it fits with the factory mounting hardware - the push pin I'm assuming. I love the PTR aluminum handguard on my 91F but I don't like needing an allen wrench to remove it.
