The r301 should have a bass magazine of 20 the same as most most of the other guns as early game before you find extended mag it just doesn't have the stopping power other weapons have the main thing...
@Hilshire12 It's base capacity is 18. That's enough to kill most players if you can hit your shots. It definitely has the stopping power, it just isn't as forgiving with the aim.
@Sir_Named I think its totally fine as it is. It's my personal favourite AR along with the Hemlock and I use it a lot. It's not hard to find a blue or purple mag for it and I think if it had a larger mag it would become op. Yes it has low damage but the recoil is so manageable and it also has a great rof. It's just consistent to put it into one word.
