Mechanic part 4

​I got gunsmith part 4 done without the 260mm barrel, which i got told was required and is currently 200k rn. Instead you can use a standard m4a1 370mm barrel which is about 30k rn.

You end up with 58 ergo, 1000 sighting range, 262 sum recoil.

I just wish i did the maths first and didnt waste 200k on the barrel scalpers
