I am thinking about putting together a PS90 from parts using an Effen90 receiver. I do already have a SBR'd PS90 that I love, and understand how the rifle works. However I have a few questions/concerns.
Parts I already have. Green stock, trigger pack, end plate, flash hider,
Parts I need to order. Effen90 receiver, barrel (once my form is back), cocking handle, cocking handle spring, barrel lock, barrel lock spring, barrel return spring, and the moving parts assembly.
MGW has everything except the barrel return spring(HDD has them), but they offer two versions of the moving parts assembly.
I always thought that the full auto bolt assembly was the same as the semi auto version. Is there a reason to get one over the other? Is there a difference?
Those of you that have seen the Effen 90 receivers, it looks like you can remove the side rails since they are held on with screws, can you confirm this?
Are there directions anywhere on how to put the receiver together? When I removed my barrel last time I followed it out with a dowel. I was told it was really hard to get it all lined up otherwise. I have seen a parts diagram, but is there a tutorial posted anywhere?
Any parts I missed?
Anything else I missed?
Any reason not to put one together this way? It probably isn't saving any money, but I already had the stock and trigger pack, and PS90's aren't in any of my local shops.
