Radical Firearms Releases 6.8 Caliber Uppers

Stafford, TX –Radical Firearms is happy to announce we’ve added a 1 in 11” twist 6.8 rifle to our long gun production lineup. The addition is a law enforcement grade, MILSPEC 16” flat top HBAR drop in upper receiver with a low profile gas block ready to mount to a MILSPEC lower receiver. The 6.8 Upper will come completely assembled, including bolt carrier group, charging handle, forward assist, barrel nut, ejection port door, A2 flash hider and of course the HBAR profile barrel.

The new upper will retail for $459.99. The reason this price is so low is, quite simply, because Radical builds everything in house. Muzzle device to buffer tube, RF manufactures it in our own facility.


As Radical’s David Spector notes,

“This give us unmatched levels of quality control and allows us to build boutique quality rifles for everyman prices.”

You will not the KeyMod rails on RF rifles are set up differently than some manufacturers. This came about due to a request by a Federal agency.

“We run them like this as a fail safe so gear doesn’t fall off accidentally. Have you ever smacked your accessory up against a door frame on a regular rail? Bye bye accessory! You don’t have to worry about that with our rails.”

    I wish there were more coma nuts doing light weight 6.8 and 6.5 barrels. I see them more as hunting calibers and don’t want a HBAR on my stalking gun.

    Keymod backwards?

    More proof that M-Lok is superior. Can’t see that ever happening.
