SARB-15 - Bullpup MWS

I am selling my SARB-15 - a bullpup MWS/AR15 rifle. Complete rifle with kit.
The base rifle is a Tokyo Marui MWS, installed in the SARB-15 kit from SRU. This kit is the version for real firearms, so it is made out of carbon reinforced nylon and built extremely well. You can read more about the kit itself on SRU's website.

The rifle comes with a short bolt with a Guns Modify nozzle and Waldo Customs return spring. It has a 4UAD hup-up rubber and nub. Shoots well and far. Output is around 1,5 J with 0,36 gram bbs at 130 psi. All other internals are standard TM.

The package also includes different buffer springs for the short bolt: A softer one to allow shooting under freezing conditions, and a stiffer one for HPA or warm summers. 
An extended MLOK front "handguard" for the SARB-15 kit is included, as well as an ordinary ar15 12,5" mlok handguard if you prefer a longer setup.
A series of vertical grips are included - all of them 3d-printed.
The original stock buffer tube is included, so you can transform it back into a normal AR15 (no full size bolt or buffer spring included though). 
One V3 Guns Modify PMAG included as well. 
Red dot is a scrapper from Vector, installed on a no-name mount. 

The rifle and kit has been used for some years, so there are wear marks. Everything is cosmetic - the rifle shoots and functions well. 

Buyer covers shipping, but I'll ship it in a rifle bag for no extra cost. 

Everything in the pictures included. All in all the new price of the package is around 1500 EUR. Get it for 800 EUR.
