Another video from AMOPS taken during the Airsoft Showcase 2016 and this features Crawley Surplus Store... "In this video overview Dan from Crawley Surplus Store talks to us about two of their 'special' products that they have on display on their stand at the Airsoft Showcase 2016 the S.R.U. BUP P1, and the S.R.U. PDW P3. The former is a conversion kit for the WE Scar-L GBBR and the latter is a conversion kit for the WE G17/18 (Gen.3). Both of these products are highly detailed, highly durable, and are made by the manufacturing process called '3D' printing."
