Gun Science!

This blog is 99.999% about guns (with a little wombat side action) and contains my internal debates, conclusions and reasons for gun... stuff... like cartridges, barrels, and spriiiings.
Billet AR Receivers: Worth the money?
A new manufacture process for AR-15/AR-10 receivers in which the receiver is 100% machined from a bar stock of aluminum. These receivers are pretty and come with some cool features like a flared mag well, ambidextrous bolt catch, and a built in trigger guard. Another thing is that the billet process allows for tighter tolerances and very tight upper to lower fit. People say the better tolerances will increase the accuracy of the rifle, but will it? Yes, but by such a small amount that you wouldn’t notice if you are not an AR fanatic. The whole reason behind it is that the forging process has some flaws in it where the dimensions are not always concentric or the rails are not always perfectly flat, where as the billet process makes it perfect every time. Now does the lower matter for accuracy? No, as long as it fits to the upper you should be fine with forged. Is the tighter tolerances worth a couple hundred more dollars? That’s up to you, if your are running an unmagnified or low powered optic you are fine, but if you are running a 5-25x50mm optic taking shots at +800 yards while trying to get that 1” group it’s worth the money.

    I have this exact weapon. The lower did cost about $100 more than a forged one, but my wife has spent that much on shoes...
