I have some of the old Bear Razorheads that I plan to use for hunting on aluminum arrows.  I am curious to what size broadhead adaptors that I need to use, 5/16" or 11/32".  If some one could assist me in this it would be greatly appreciated.  Thanks,  Jeremy

11/32" short adaptor will put you in business and allow you to use the bleeder blades  

Chuck,

Thanks for the info.

Your Welcome!!!!! Good Luck with them!!!!!

Last September,my good friend and next door nieghbor passed away and his wife gave me all of his old hunting equipment.Among the assorted archery gear were about 3 dozen old green Razorheads. (some with inserts,some without) I mounted some glue-ons on my woodies and some screw-ons on my aluminiums. (2016 "autumn orange" XX75's that used to belong to my friend Lew)

I'll be using them for a LONG time.....  

5/16" fit better.

Chuck,

That sounds awesome.  It's kind of like spending time in the woods with your old friend when you take those Razorheads and arrows hunting.  The spirt lives on.  

I'm also shooting 2016 aluminum.  Thanks for all your help.  This was my first post to TradGang and you made the experience great.

Glad I could help,Good Luck My Friend!!!!!
