Fulcrum goes over the Specna Arms PRIME MK18 AEG, a licensed Daniel Defense replica that trades the polymer of its cheaper siblings for a metal exterior. While the build quality feels solid, he was slightly let down to find that the imitation bolt release is purely for show, unlike on some other models. It seems that even when you pay for the "Prime" experience, some parts of the gun prefer to remain stationary and unbothered.
