Silverback Airsoft that the DesertTech SRS Sniper Model 2018 will be released next month... "Hi All! The current version of the SRS is discontinued, a new version, Model 2018, will hit the market mid-October. The Pull bolt system has prevailed, the Push bolt system SRS is discontinued (conversion kit will still be produced).

What’s new:

• Piston: heavier than the previous one (54g instead of 40g), piston end is a bit different for smoother loking on the sear, the head is now a silent cup type.
• Hop up: new rubber, flat type design, better seal and easier to lift heavy bb’s (also compatible with the optional fast hop-up).
• Magazine: SRS are now coming with the black magazine (SBA-MAG-03BK, long flexible follower included)
• Trigger box/safety: design of the safety has been modified, safety buttons are now encased in the safety plate.
• Pull bolt buttplate extension: better fit with the spring guide, reducing vibrations.
• BB tube: there is no O-Ring anymore in the bb tube, last year evolution was not up to our expectations, so SRS will lose 4 bbs when you remove your empty mag, unless you are using a long magazine follower.
• Nylon side rails design is a bit different, closer to the original.

All new parts will be available as spare within a few days, you can check the new user manual, it will answer most of your question.

We are also launching a new website today, you will find additional pictures of the items above, and probably a little bit more…. www.silverback-airsoft.com."
