In what way? "... the first thing I noticed was how uncomfortable the 18hole “radial brake” was."
First- The shockwave that hits you in the face Everytime you pull the trigger. Million posts on the web about the MPR and the brake that comes on it.
Second- the noise.
I totally concur. My girlfriend has one and the damn thing was too obnoxious to shoot. She complained about it and I tried it out and she was right. Ruger had their heads up their azzes on that one. I replaced the one she had with a linear comp and it is much better now. A few weekends ago, my girlfriend and I went to one of my buddies houses and we were shooting our AR's. My buddy has the MPR and my girlfriend said she wanted to see if his was as obnoxious as hers used to be and he said she could shoot it, but we all felt the muzzle blast from his rifle. It wasn't even necessary to get directly behind it and shoot it because it was so obvious. She said, "no, I don't need to shoot it". "I can tell from 10' back that it is bad"!!!
