Welcome to the clan, UG, from the great state of Texas! There are threads buried in this tab relating to a Grendel that I built for my nephew. He fell out of a tree stand and broke his back and is now paralyzed from the ribcage down and with limited strength up. I built him a 20" and you can hold it at arms length when firing with virtually no recoil. The keys are a good muzzle brake and the longest practical gas system for the chosen barrel length. Using a longer gas tube spreads the recoil impulse out over time so that the associated weight of the rifle overcomes the majority of the recoil impulse. To date, he has taken several deer and coyotes with it.
