We need green guns to make a comeback and dethrone the black/tan two tone zeitgeist.
Yes.
Good eye, yes it did! (Here is an alternative link if the one above doesn't work for people as it didn't for me.)
I purchased it originally from EHobbyAsia in June 2013. It cost me $364.80USD. I really love the look of it - the mid-length barrel combined with a full length M203 just looks really kino to me. And yes, all the tan Magpul parts were made by PTS during their official partnership, and are probably quite rare these days.
I started switching over to Olive Drab furniture as I gradually stopped wearing Multicam gear. I never found any kosher Magpul PTS bits in olive drab, so mixed and matched with RS Magpul and PTS parts;
The ACS stock, rifle-length handguard, and front BUIS are all RS Magpul. The rear BUIS is (I think) "old new" Magpul PTS stock from Firesupport. The motor grip and magazines are contemporary PTS-make, and luckily the Magpul design aesthetic is still very much in PTS's DNA despite the partnership with Magpul being over for a very long time. The M203 grip and ACOG are spray painted with Olive Drab Krylon, again from Firesupport.
I've shifted the rear BUIS forward so the ACOG sits behind it, and it all fits quite comfortably on the top rail without interfering with the charging handle. Luke/Negative Airsoft did mention that the front BUIS atop G&G railed gas-block did cause some consternation with his viewers, but admitted that there was nowhere else to put it. I love how it looks and how I can flatten the iron sights for use with any red dot or other sight, like Old Snake's M4 Custom from MGS4.
I do want to have a magnified optic though, and am willing to ditch the ACOG for anything with better eye relief as long as it's not an LVPO (cos they look too much like a sniper's scope in my opinion).
