Hi guys is there a venturi bolt that fits the mr1?

Any spyder bolt will drop in. Maybe a little modding to add a cocking rod.

Why a venturi bolt? They have been proven to be worse than a non venturi bolt.

Just about any NON venturi bolt. ACP is about the only company making new bolt but Ive seen several sales with GOOD older bolts worth what they were asking.

to my knowledge the mr1 bolt is a venturi bolt..

look down the center..if you see a flower or star shape then you have a venturi bolt.

get a low blow

The MR-1 comes with a venturi bolt stock.

ACP has decent delrin bolts that fit the MR-1 and work find. Low-blow not required.

The big difference I noticed when I switched bolts was about 5-10 fps with the non-venturi delrin bolt.
