I don't think you can get sepearte fittings for the G&P ones but you could probably pick up the Dboys/E&C 3in1 version new cheaper than your mates one anyway. They come will all three types of fitting (including RIS).
Ah, right! You'll be needing a speedloader then! http://www.ebay.co.uk/itm/AIRSOFT-BB-BBS-XL-470RDS-6MM-SPEED-LOADER-FAST-UK-DELIVERY-extra-large-mid-cap-/371070847315?pt=UK_SportingGoods_Hunting_ShootingSports_ET&hash=item56658bc953
Right, so if you just want it as a non firing prop, why do you need a magazine? The bottom part as you say completely covers the magazine anyway so you'll never see it. You can't fix the mag to the clip to be able to slap one in like the film either because the innards of the magwell don't match the magazine used in the film...
There is an airsoft Colonial Marines group that might be more able to help out though.. https://www.facebook.com/groups/426066200772765/?fref=ts
Again - Viper 3 point tactical sling. It comes with a loop that will go through the sling point on your stock and a hook at the other end for the front ring. It also has the adjustment loop and fastex clip mid length like your SA80 sling does which will allow you to carry it in multiple configurations. Plus, being Viper - it's dirt cheap.
Have a look at the Viper 3 point tactical sling. It has a similar system to the one you already have but it also has a hook that will work with your front sling hole.
Nothing off the shelf will fit perfectly. But if you look on the DIY thread you'll see how to mod the mask to fit better. Any decent set of goggles will work fine but you'll need to make the effort if you want to minimise fogging. Revision Desert Locust seems pretty popular, could also try Bolle X1000 or my personal preference ESS V12 Advancers.
No, but your reply could easily have been misinterpreted.
Just FYI, JT Sports, Dye, Sly and Proto are all decent makers of paintball masks (among other kit) that are more than acceptable for airsoft use.
Maybe you should do a bit of research then.
JT sports have been around for donkeys years in the paintball world, they make good if not stellar gear. That mask is absolutely fine but will probably fog up quicker than a peados glasses on a rainy day in the playground.
I've got to say - if I'd wanted to shlep around the woods in combat gear carrying a gun in the pissing rain getting wet and cold for 8 hours at a time, I'd have joined the army.
Snow intrigues me though. Cold I can do, cold and wet? Fuck that for a game of soldiers.
(see what I did there?)
