The tricky part about actually finishing some of my recent airsoft builds is the little details. The larger parts that really change up the weight, feel and aesthetic are comparatively easier to decide on and get hold of, but it took more hunting around for the smaller touches that make something genuinely different (at least to the eye of the keen observer). Manufacturers by and large tend to ship out rifles with all sorts of different stocks, grips and forends but usually it’s fictional stuff, and even if the small items like the trigger and selector aren’t just the plain old USGI designs then again it’s usually not a pattern that really exists on a firearm and I’m not personally a fan of that look.
The other aspect is that airsoft brands copy firearm products more than people realise, it’s not as common now but historically it happened a lot and they just never put the original name to the item to save themselves legal hassle. So again tracking down that replica part takes a lot of trawling and you have to have the prerequisite knowledge. A couple of stores I like for these small parts and accessories are ehobbyasia.com in Hong Kong and Dave’s Custom Airsoft LTD here in the UK. At the time of writing eHobby actually carry some quality gear like G-Code Holsters and a lot of other items that US stores won’t let you export as an individual because of the pointlessly over-reaching arse covering exercise that is elements of ITAR, so that’s handy.
One thing I’ll say is I strongly recommend avoiding APS like the plague. I’d always gotten the impression just from the look of their stuff online and the pricing that the quality would be pretty dire and my suspicions were thoroughly confirmed. I figured hey it’s an anti-rotation link for an AEG, purely cosmetic item so why not? Now I may have a biased view because of my work, but the metal on these things is in my opinion the living embodiment of that old trope when they say something is “made of cheese”. The no-name ACM charging handles also took work on the dremel to fit my particular RIFs but I almost prefer that in a way, it’s a lot more satisfying when they eventually fit and work. That said, if higher quality alternatives were common and stocked widely I’d opt for them. They generally aren’t however because that market is fairly dead these days in the realm of AEGs.
