Looking for shell ejecting + recoil replicas

Hello everyone,

In order to build a small collection of replicas used as movie props, I am actively looking some full metal kinds of replicas, with shell ejecting and recoil. 

I know those replicas are rares but if someone here got some, I could be interested.

(however I am not interested by models without those characteristics, and I am not looking for: shotguns, revolvers or old rifles)

I am looking for some precise models of assault rifles, pistols and precision rifles :

-M-4 or AR-15. 
-Colt 1911. 
-Glock. 
-Beretta. 
-M-700 or M40A. 
-Barrett 107.

Well, if you have this kind of stuff in stock, you could have a buyer.

Best regards

Alex
