Product Description


The ZNIPER Zextant plunger comes in 4 sizes for a perfect fit on your bow with either stick-on or bolt-on rest.

Questions (1)
was looking at matching this up with a Zniper arrow rest and a Black Elk riser. Would the Small size Zniper Zextant be sufficient for my needs?

Ive just had a look and the small looks to be too short for the Black Elk Riser.
