Very nice review. I'm kind of on the fence about picking one of these up. I recently finished my AEG build and was looking for something cheap to turn into an HPA platform. I've always had a soft spot for the HK416 but getting the VFC is simply too expensive if I'm going to gut the thing. At first I was looking at the Specna Arms sa-h02 but I can't find them anywhere and again the newer version, the sa-h20 is too much because of the Gate Aster. Long story short I'm only looking for good quality externals.
Would you recommend the Double Bell HK style replicas and would it be worth it to upgrade the hopup chamber as well as the inner barrel (shorter version)?
I kind of like the fact that the DB ones don't have 'trades' like the SA one so I can have them laser engraved locally.
