The inside diameter ( ID )
of the Grizzly stick is close to 9/32 0r .28100 we make our inserts about .275 so we know they will fit .We also taper them slightly ,001 so the can be started into the arrow. All arrows measurements vary regardless what the manufactures stipulate.
We call the OD. 11/32. following industry standards and refer to this insert on our web site for !1/32 arrows. It all makes about as much sense as arrow designations between manufactures
Having said that we have in stock just 200 grain for the 11/32 grizzly stick arrow and since they are custom made , like all of our inserts ,it will be a while before they are in production. Sorry
i am not positive but do not believe this size adaptor fits or interchanges with other arrow brands…. May be some else has had experience with this.
JIM B Shame on you for forgetting us.
