2. ALL GBBRs are temp sensitive. About 15deg C and you'll dump a mag...more so with the open bolt. NONE of them work very well in FA in the cold on propane. Semi is so-so in cold weather. CO2...semi isn't an issue, can't comment on CO2 on full auto in the sub-10deg weather.
3. It's somewhat of a moot point in practice. Most times you are faced with the opportunity to "take a break" and reload...where you would be silly not to top off with gas as well. Either a between sets break...or a resupply opportunity in a milsim. However, on propane, you'll usually get a mag and a half of BBs dependably...more with the open bolt. More with semi...less so with full auto.
4. Best to ask whomever you're buying from to confirm that batch right then and there. Also, with some setups that allow for barrel extensions...the short barrel may finish with one thread, and the tip of the extension might finish with the reverse. |
LOL this came a tad late :P I've been playing and dissembling my SCAR since I got it in March :P
For 2; the mags are still crap and I can't get blue gasket sealant in HK. Asked a friend to get me some from home depot or canadian tire here so I should get it once hes back for christmas :P
For 3, it's a moot point but I what I was trying to get at was if I were to modify the mags or gun such that the setup uses more gas than the stock gun the mags would still have sufficient gas to push out all 30 bbs. Actually speaking of the RATECH bolt I heard it's crap (through a friend who's been browsing ASC's other SCAR thread). The Gunsmodify one is lighter and should work better (also more aesthetically correct). I'm not sinking more money to the SCAR for now as I realised the ergonomics of the gun is not as suitable for me compared to an M4 (mostly the butt-stock being too concave, the tip of the stock digs into my chest too much). My money's being spent on AEG builds at the moment as I've been trying to do some crazy stuff with AEGs ever since I found out about their potential to shoot some 60 rps on a single sector build
For 4, I can confirm it's -14mm. I've attached the VFC long barrel extension and it fits, although the WE SCAR barrel is a lighter shade of grey (VFC's black) so you'll see some colouring issues where the 2 barrels meet (the gas block area).
