After much reading here before a couple of builds I decided to buy the lapping tool. My dad kind of gave me one of those looks, like I was smoking something. And much debate with someone that is as stubborn as I am, I asked him what will it hurt? Well he could not really answer that, so he actually ordered the tool before I could. When we started to put together the 300 blk rifles I was the first one to lap the receiver. You should have seen his face when it started to look like the receiver in LRRP's first picture.
Now I cannot say for sure what it did for the accuracy of this rifle, I can say it shoots much better than I thought it would. With a $135 SS barrel, with nice finish quality, and a nice looking bore. I will get a chance to do some testing but both his rifle, and the rifle I built for the wife is showing MOA accuracy. So my carbine is a 16" Wilson SS NM 1-8 chambered in 223 wylde. This rifle is already MOA or better with my 55gr FMJ loads, and put down some amazing shots at 500yds with 77gr SMK's. I tore this thing down to refinish it, and it will be lapped with the tool. The price of the tool kind of makes it a no brainier when building uppers.
