Just looking for advice on which type (and is readily available) of BUIS fits the Canadian C7 service rifle upper receiver rails (Weaver?). I'd rather not use the issue plactic POS and it will be used in conjunction (co-witnessed) with an Eotech 552 and a BU to an ACOG.

I've heard the Troy Industries works on our rails and I was going to order one through Brownells in the States. Any better suggestions?

Thanks.
 
Any of the modern back up sites will work that are for rail mounting. The one you choose is personal preference, as every person likes different sights. I would stick with one for a known manufacturer like:

Troy
Magpul
YHM
GGG
Midwest ind

I am sure there are more but I can't remember them right now. As for getting one check with some of the dealers above. I would suggest Dave's Surplus, Oneshot Tactical or Wolverine Supplies.

YMMV

From what I understand the rails on the Diemaco C7 upper receivers are not M1913 spec and not all the BUIS's out there fit all that well.

I'll probably get a Troy from One Shot as I just put in an order with them for some other stuff.
 
I used a KAC 300m BIUS over seas. ARMS 40 should fit, it's in the system for issue to some units (no I'm not in one of them).

Mistake in first post, put the ARMS on my personal carbine, not my C8. The KAC is good to go.

I had an ARMS40L that didnt fit on my work upper, the ARMS BUIS in the system has been modded to fit our non spec rails.
 
If you want an ARMS BUIS get the #40C it is configured for the archaic Weaver rails on out rifles.
Personally I prefer the Troy system YMMV
