Ok so I picked up an Aero-chamber hop-up unit for my CA M24, now I bought this on the impression that it would drop right in and function. Of course I was lied to, it doesn't fit into the position it should is there anything I can do to make it work?? Or should I just bite the bullet and buy a PDI that will work?

We have an entire section devoted to the Classic Army rifles.

I answered this same exact question when you asked it on MIA, and the answer remains the same.

The aero chamber is designed for an APS 2, and is one of the only items that isn't interchangeable between the M24 and APS.
