Hey hi hello. Here is one design of a few railed outer barrel extensions I've been working on for the AAP-01 GBB airsoft pistol.
This is a replacement for the original outer barrel and uses the same screws so make sure you have those hand.
 

So recently I've had a bit of a personal dilemma. I've always wanted to experiment with a DMR kit/extension but I've always hated the most common ones out there. 
Their pseudo-futuristic-frankenstein appearance just really doesn't do it for me and I love my AAP-01 far too much to taint it that way.
 

What I do like however is Big. Chonky. Hand Cannons. Especially the Desert Eagle.

Which is where I got the idea for this design.  I wanted something sleak enough to serve as a standalone pistol but long enough for a potential DMR loadout whenever I felt like slapping a stock and a foregrip on without it looking like some rejected Battlefield 4 concept art or just a simple afterthought. 
 

My crap patter aside here's a look at the unit itself:

- This replaces the pistol's default outer barrel so make sure you're familiar with how to remove and replace that first. (Its not difficult, its just a two different types of hex head screws).
- Outer barrel length is approximately 178mm in length. (it fits the official Action Army 200mm inner barrel with a bit of room to spare.)
- Outer barrel width is 30mm. 
- The top rail is about 235mm in length
- The bottom rail is around 169mm in length.
- Printed in PLA at 50% infill. Sturdy but not unbreakable. Its not CNC Steel so don't go treating it like it is.
- Lightweight at approximately 180g (according to filament used in Simplify3D)


 

PLEASE NOTE THE FOLLOWING BEFORE YOU BUY:
These are made to order. I will always try to get UK orders sent out first but as I have this listed on more international sites I get a lot of attraction from yankee airsofters across the pond which clogs up my work load. Please allow for 4-7 days production but if its urgent feel free to drop me a message prior and I'll see what I can do. 
 

The stand out bit of the top rail is a weak point due to it's dimensions and will most likely break if mishandled or dropped especially if you have a large optic mounted there. If it does snap off the barrel can still be secured without that top screw mounting point and I'm actually going to list a version without the sticky-outy top rail in the future because it can be paired with the official Action Army AAP-01 top rail and secured together with the optic's mount or a rail riser for a full front-to-back top rail.
 

The sloped end of the muzzle has an imperfect finish which is unfortunately unavoidable due to the way it has to be printed with supports but I know it can be done better so I'm always looking into ways to lessen its ugliness. I've tried to show this in one of the images. The best fix for this is to sand it down gently with some 300-500 grit sandpaper then buff it out and repaint it.

I'd advise painting it to match your AAP-01's top slide/receiver portion anyway for a nice uniform look.
