Taper Pin Reamer
Checked "Right Tool" in the "Pros" column, because it is the correct size and shape for AR Taper Pin holes. Remove and throw the plastic handle away, replace with a "T" handle or better to chuck in drill press in order to get enough pressure to cut the correct taper for front sight pins. Installed two AR front sights, not sure the tool will hold up long enough to do a third.
Bad experience
Brock almost immediately. After receiving it I thought it would. But I tried it anyway. Did not even get 1 full use out of it. I was not that hard on it. I am returning for a refund. I would look for another option, this one is not a deal.
Why is this the only option on Brownells
This reamer is cheaply made. The handle is useless. It just makes the picture of the tool on the website look more user friendly. The reamer broke before I finished the taper. You may have more luck with yours but no one in their right mind would claim this tool could install more than one sight block.
Mission not accomplished
This type of tool is a great idea, however this one falls short and has several flaws. The handle loosened after a few turns and had to be discarded. The tool was eventually chucked in a drill press, as the flutes were found to be not efficient for hand reaming. Nothing worse then ordering a special tool for a job then finding out it is not effective. Better off just buying a 2/0 reamer from the local tool supply.
Not well made
Brownells, I love you, but this product is subpar. The plastic handle slips off the metal with the slightest bit of resistance. Totally ineffective for something that's supposed to ream metal.
