New "Bump Fire System" coming for Scorpions?

[Shady]

seeing its not like a bump fire stock and it has something that pulls the trigger for you I would want to see an approval letter before I sent any hard earned cash

There is one on their site. https://www.bairarms.com/pages/atf-approval

I think I will wait a while before I even consider this.

9mm has a bad habit of suffering from out of battery detonations while bump firing.

True, but doesn't the firing pin block in the EVO prevent OOB detonations ?

There has been atleast one oob with the scorpion that was on ar15.com.
I'm not sure how it could have happened since the firing pin safety should prevent that, but my guess is the fp safety disengages a fairly wide range when the bolt is closed, which may allow for pin movement is the round is just barely not chambered? I will have to try this tonight with a pencil....

Thanks for that I had not seen it.

Its easy to out run the bolt on an AK and AR both just by using a little too much forward pressure. Too much forward pressure = light primer strike. 9mm blow back bolt carbines are much more forgiving to bump shoot with heavier triggers and without out running your bolt.

Have you had any issues with the bolt out running. With the retarder the auto trigger pack uses I just curious is all. I bump fire ak rifles a lot Ive never had a problem. I'm just curious is all.

I've bumped out over 2 cases of 9mm ammo last year and my only oobd's (3) came from glock mag carbines. Both my PSA 9mm glock mag rifles cannot seem to chamber 20 rounds per second.

I think I will wait a while before I even consider this.

Yeah, me too! I bet it would not be an issue though.

I would be interested as well if it will work with my HBi flat trigger.

Any idea on when these will be in stock?

[Magnum Mike]

Here you go guys. Preorder them while you can. We uploaded a new video from a range where we could shoot FA. Check it out.

I just made a new topic with pretty order info

I wonder if it will work with all the modifications to my Scorpion.

I have the Yeti Wurks Switchback grip with a Hogue slip-on, Shooter's Element flat trigger, and an HBI trigger spring.

Does anyone know if they sell left-hand models?

[Magnum Mike]

Dave, it should work but that configuration has not been tested. If it doesn't fit and break your trigger in dry fire you can send it back for a refund.

ATF said that this device on a pistol "could" be considered an AOW. I don't agree since you can absolutely fire a pistol with one hand as originally designed with this device installed. Just like an angled foregrip

Curious why he specifies that it is not approved for pistols.
