I have, sadly, admitted that I prefer playing with my DMR over my sniper rifle, so here is my beloved Silverback SRS A2 16" Sportline, and a whole bunch of upgrades.

This is everything you need for a great sniper set up.
 

1x Silverback SRS A2 16" Sportline
Originally black, it has had a custom paint job, as you can see.
The gun is used, but not worn out by a long way. I have fielded it probably 5 or 6 full days. There is some superficial wear to it, but no damage. 
It is working perfectly.
The base gun comes with the piston, bolt sleeve assembly and spring disassembled, as you would receive it brand new.
You can assemble it with the default spring and piston, which are included, or set the rifle up to suit you with any of these upgrades which are included in this sale:

1x Sniper Mechanics W.A.S.P. piston package (This is brand new, had around 10 rounds through it, never fielded)
1x Silverback FAST hop unit (Sealed in box, not fitted) 
4x Silverback 70 degree SBA buckings with 4 matching nubs (Sealed in box, not fitted)
2x Silverback v1 ‘chub nubs’ (Sealed in box, not fitted)
2x Silverback 120 Newton springs
1x Silverback 95 Newton spring
1x Rapax 2+ Joule/Blue spring
1x Rapax 3+ Joule/Red spring
2x Extra mags (3 total)
1x Silverback magazine pouch (Molle/PALS)

All original packaging, including Silverback brand grease, and Silverback Airsoft patch.

I would obviously prefer collection, but will post at buyer's expense.
Payment via Paypal G&S.

Buy this, grab your grandma's plastic ferns and zip tie them to your boonie and you're all set.
