It looks the trend is having more compact sniper rifles in airsoft and in this video Geonox Airsoft checks out one, the BTG Compact Sniper... "Here we look at the BTG Compact Sniper. It is a spring pressure airsoft. Since it has an energy of 0.5 joules, you can play it on a game day for ages 14 and up.

This is a good custom project as Chris Adams Custom reduced the size of the Cybergun FNX-45 GBB Pistol, giving it a more compact look... "Here is the beginning of one of my parallel project, I like the FNX, but... It is a bit too large according to my needs, I am a big fan of the P226 since the eighties. Therefore, My intention was to reduce the size of one of my FNX, to be as close as possible to a Sig dimensions."

If you are looking for the Umarex H&K USP Compact, you can find it at WGC Shop where they are retailing it for US$155.00. The lower frame is made of ABS whilst the slide is full metal. Since it's a compact version, the length is 185mm and has an initial muzzle velocity of 270-300fps using .20g BBs and Top Gas. Package includes the pistol, magazine, and manual.
