Hi all, I have been into airsoft for around 6 years now and I have always loved the designs of bullpup rifles. Unfortunately I am not satisfied with any available airsoft options. I have done extensive research on pullpup builds and things of the sort recently and have done a few photoshop mockups of builds I want to try and none are really working out. So, does anyone on these forums know of any real steel or airsoft drop in kits that are still available? If so please tell me. Also if anyone on here has done a custom bullpup build please post pics! Lastly one idea I have is to cut up a p90 or G&G fn2000 but I need a pic of the insides where the gun body is split in half with the gearbox still in it, I will attach a picture specifying what I mean unfortunately the picture I will include does not have the gearbox which is why I need a pic from you guys! Thanks so much!
