    Hey was wondering what size width the inside of the hand gaurd is I
    bought one of these with a 10.5" barrel with the FGS Handguard I wanted
    to buy a Flash Can Concussion Linear Brake for it to replace the muzzle
    that comes with it and dont want to wait till gun gets here to order one
    and want to make sure I dont buy one thats to wide because I know that
    1/2 x 28 threads sit inside the handgaurd a bit Thanks

    what type are those additional rails? radical says MOE will work…but that means the hand guard needs to be removed

    I believe the handguard is 1.56" which makes it suppressor/flash can friendly. I’m going to use one of their 12" rails and mount my suppressor under it, it’ll look very nice 🙂

    Travis, do you have a video of the Radical 8.5 shooting sub-sonic ammo ? If so would you please copy and paste the vid link in a reply to this comment. If not, would you please post a short video showing the pistol shooting sub-sonic ammo ? Thank you in advance for your consideration of this matter.

    Been buying Radical Firearms products for years… They’re honestly one of the best kept secrets out there. I actually moved to Richmond TX a couple years back for a job, realized the office was a few miles away and I stopped in to meet a few of the guys. GREAT guys who just enjoy building firearms and they’ve gotten REALLY REALLY GOOD at it.
