Bump Firing A SCAR16S

FourGuysGuns take a Suppressed SBR SCAR16S and bump fire it with a Magpul D60 drum mag feeding it. It is rather impressive the rate of fire they are getting out of this SCAR16S. I wonder what trigger they are running? Possibly a Geissele? I do not think you can get this rate of fire out of the factory trigger.

    “I do not think you can get this rate of fire out of the factory trigger.”

    You may be shocked what relatively poor, gritty factory triggers are capable of. I agree that’s likely an aftermarket, but an ordinary milspec FCG on an AR-15 is perfectly capable of bump-firing at 500+RPM with an experienced shooter. With a Geissele, maxing out the cyclic is normal when bump-firing.

    With a Geissele, Rise, Timney, or other crisp trigger and a light (Al or Ti) BCG in an AR, going past 1,000RPM is possible, and also hilarious.

    Without a look at the target, who cares?

    I find myself bump firing my 16s a lot more, I did just yesterday! I have a dbal, Acog and a sure fire light and let me tell you, ithe weight helps. Super fun way to blast $$ out of your wallet!

    I’m curios about the difference in timing, if any, compared to an ar15. I know I have actually out ran the action bump firing with a rise armament trigger. At least I am assuming the sear released before battery because a cartridge was chambered, but the primer wasn’t marked. It seems like a positive reset makes more difference than an overall “good” trigger when bump firing. I’ve seen videos in 3 gun where they shot too fast, but I’m not sure if they out ran the action or the magazine.

    You’d get it out of a factory trigger if you contacted your canidates for federal office and held their feat to the fire about NFA repeal.
