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.

A highlight is the TDC (Top Dead Center). I don't know of any 0.5 Joule Sniper that has a TDC installed out of the box. The TDC presses the hopup rubber down perfectly in the middle from above. This ensures very good precision and range.

An upgrade bucking with a large patch area is already installed. This means that the hopup rubber has maximum contact area with the BB.

The BTG Compact Sniper has a short stroke. The repeating travel is 45mm shorter. This means you can repeat faster."
