Poseidon Custom 17 replica with TWO slide sets!

Poseidon, who's other brand is B&W, a relatively new Taiwanese manufacturer have now directly cloned the Tokyo Marui 17 and then upgraded the daylights out of it with all Poseidon parts, calling it the H17

So just like the TM version, this is a full polymer build with all the necessary trigger and innards in metal. This one however, has custom upgraded innards, a threaded outer barrel, a 'Gucci' aluminium alloy slide set AND a lighter CNC aluminium RMR slide set, both with super cool design cut-outs. Both slides are complete, so you can quick-swap as required.

The Poseidon B&W H17 is fully TM compatible and accepts all TM spares and mags, although we're not sure why you would want to......

You will receive 2 slides and 2 outer barrels (pictured)

Where supplied, Chinese batteries and chargers are warrantied to be not DOA (Dead on Arrival) only. We always recommend swapping out to a better quality battery and charger at the earliest opportunity.

Custom Painted products (Two-Tone) are non-refundable as these are painted to order. 

Unless otherwise stated, all products are sold singly.



Any figures used are based on tests performed on the products when they are first listed. These can vary due to changes by the manufacturer, gas pressure, gas used and a number of other factors. All figures should be treated as an approximate guide and used for reference only. 

All listed FPS are +/- 5% due to differences from rifle to rifle. If you require a guaranteed FPS, please add an upgrade/downgrade option on to your product (this may cost extra).

No airsoft AEG is warrantied for use with an 11.1v LiPo or higher voltage battery at UK velocities (373fps or lower) unless specifically recommended on the product itself. Use of higher voltage batteries can cause failures and will negate any warranty implied or otherwise.
