A better starter gun would be a G&G Wombat Musheen* M4.
Proven to be more reliable and more mag friendly,no fiddly things to do. APS UAR is great and all,but not idea for a starter gun due to little niggles that need sorting.
*Combat Machine,I've got the reddit disease :[
No.
APS claim it's designed for airsoft from the ground up, but if you ask me, it looks somewhat similar to the MSBS Radon, which is a bullpup version, of the Polish version of the ACR/Masada.
