If they don't make the 1:8 5R barrel then how come my VTAC II supposedly has one (I will now have to go downstairs and look at the barrel). It was purchased with in the past year.
The 1:8 5R barrel on your VTAC II is different than the 1:8 5R barrel that was on the Sport... Made of different grades of steel.
They still make both varieties, just they don't use one on the Sport. Now the 15T is the only one that I am aware of that comes with the 1:8 5R barrel made from 4140 steel. The MOE Mid and VTAC II have 4150 steel.
What do the different grades of steel mean? Absolutely nothing to 99.9% of us. 4150 has just a little more carbon.
