I'm sorry for being so dense. I understand the principle but I'm hesitant to cut on the FSG any more without a picture or two.
If you wouldn't mind shooting a pic or two, I'd greatly appreciate it. I've read and reread your posting, and viewed the pics over and over.
I guess if I know what/where to chop off, I'll try cutting it again.
BTW, I just got my KNS LL protector. It's one tight fit, getting the rear pin pushed thru. I actually filed down the upper pin area (on the bottom) a little and now it shuts nicely. I didn't have any problems without the KNS.
Now to get it out and shooting. I haven't gotten a chance to shoot it yet. I think about maybe getting an 11" upper from Armalite, just to make more noise/flash on the line. (Don't know if I want to SBR it tho)
BTW, the LL works great in 5.56.
Hope it works as well in the Armalite.
