View Full Version : CA m15a4 Upgrades

I have 2 questions that pertain to barrel upgrades.

I was looking on WGC at inner barrels for the Classic Army M15a4 and I noticed their were 2 different types of systemas. One was a normal 6.04mm Inner barrel and the other one was a systema BS inner barrel and it was significantly cheaper. What is the difference between the 2 types?

Then, on War 4 Toys I noticed that they had a First Factory 6.03mm Barrel for about the same price as the 6.04mm. Is there anything I should know about 6.03mm barrels to help me make my choice on a new inner barrel?
