Re: Taran Carrier (lifter, elevator, whatever)
I've put TTI's carrier in several of my guns and was going to do it on my M4. However, like you, it hasn't bitten me yet. The pic below shows why (IMHO). Left is M1/2(I can't remember which) with a TTI. Right is M1/2 with factory carrier. Middle is the M4. The factory M4 extends further into the loading port and the shape of the tip is different than that of the factory M1/2. The M1/2 will definitely grab your thumb during a hurried standard reload. There's not as much room between the end of the M4's carrier and the front of the receiver so the thumb-bite, I've found, is much less likely. Hence, I didn't see the need to change it out. But that's just me.
