BEN en 3D talks about its new 3D printed kit. The BENen3D MSBS Grot Conversion Kit transforms an A&K AEG ACR into a C10.5A2 or C16A2 model, featuring a new 10.5" or 16" M-Lok handguard, foldable and adjustable stock, and a signature MSBS muzzle brake/flash hider. This kit maintains battery compatibility both at the front, like the original ACR, and in the stock, offering flexibility for airsoft enthusiasts.
