I am new to this forum so if this question has been answered before I am sorry, but is it possible to add iron sights to the Axis or is the barrel to thin? I had read a few reviews saying barrels were thin enough to heat up after just a few shots. I do not own an Axis yet just curious, I am stuck between the Axis and the HogHunter any suggestions. Unfortunately I am on a very tight budget with this rifle.
