Apologies in advance if <See SiteNews> links aren't allowed; What do you guys make of this to fit to a GSG 5? http://www.<See SiteNews>.co.uk/itm/New-Metal-Airsoft-RIS-Rail-Handguard-AEG-MP5-/320879639604?pt=LH_DefaultDomain_0&hash=item4ab5eabc34#ht_2140wt_905 It looks like it has the hole for the push pin, provided that all lines up and I get a shorter screw for under the barrel, what else would it need to fit securely? I don't see a collar included. Over here in the UK we're a bit stifled for parts without importing them from the US or massive price hikes. Oh and there's 3 left apparently. Please don't buy them all before me! -edit- I see the forum removes the word, it's the well known auction site!
