Replacement/ Building a New TM Glock 17 Hop Up

[Kungpow]

I have some extra parts laying around to make a new slide assembly. All I need is a Glock 17/18 hop up assembly. Is there any WE/TM Hop Ups pre built? I have found a few hop up parts but I am missing a few.

What I am looking for is TM Glock part NO#: 12, 20 and 21
I cannot seem to find these parts, and are preventing me from assembling a new hop up.

Those pieces are the hop tension arm and dial + oring?

In the classifieds there are a few ppl selling those parts. They are for the 1911 model I think.. but I'm 99% sure they are identical in the glock.. also u can probably find the same pieces from hong Kong sites by searchin hop dial and tension arm!

Part 12 is just a hop-up tensioner: Prog4 does them for hi-capa and is compatible with G17.

Part 20 + 21 is just a generic hop-up dial + o-ring which again is common between 1911 and G17.
