Hi all,
I'm new to the Forum, but not to Bullpup rifles. And, I share with others of our sport-shooting community the disappointment that Kel-Tec and K&M Arms will not be producing their respective Bullpup models chambered for the 6.5mm Grendel cartridge, as promised.
A few years ago, I built a Bullpup rifle based on the AR-15 platform, with switch Barrels and Bolts chambered/machined for the 5.56x45mm and 6.5mm Grendel cartridges ---
However, I never did get comfortable with the fact that the AR-15 Bolt face, 0.378" diameter, has to be opened to 0.440" to accept the 6.5mm Grendel cartridge. I was reminded to the cartridge developer's warning,
"We shoehorned a bigger cartridge into the gun . . . Add the 6.5mm Grendel geometry, and you are right at the tipping point."
Now, CMMG offers their 6.5mm Grendel Pistol Banshee MKW-15, 12.5" barrel, with their PowerBolt (AR-10 Bolt) ---
However, in that this model is classified as a Pistol, adding a vertical fore grip can conflict with federal regulations:
Can I Add a Vertical Fore Grip to My AR-15 Pistol? <
www.guntrustguru.com/can-i-add-a-vertical-fore-grip-to-my-ar-15-pistol.html > I contacted CMMG Tech Support and asked the overall length of the pistol, with the flash hider removed. The answer,
"About 27.3 inches, roughly." That overall length allows the owner of the CMMG pistol to attach a vertical grip, legally.
