I almost pulled the trigger on the m4 but then found out they got rid of the 1st reg. Why did they get rid of the first reg for? To save cost? Or were ppl having too much problem with the 1st reg. I think I saw where ppl say they getting leaks from it. If fx got rid of the 1st reg then why sell it for $2199? Why not sell for $2000 since you removed the 1st reg and put a plug in. Now we have to spend $40 on a new gauge and $100-150 to get complete 1st reg to install on the m4. I could just get a m3 but the m4 look way cooler with other upgrades so why would I downgrade to the m3. But I am not gonna get the m4 due to them removing the 1st reg. Aint gonna spend $150-200 extra to install that. The reason I want 1st reg is to use 300 bar bottle and also lower the bottle pressure from 300 bar to 180 bar b4 it goes into the 2nd reg so less stress on 2nd reg. It will also creep less and also get more shots. Isnt that the reason they put the 1st reg in the m3? To battle reg creep and put less stress on the 2nd reg. Can't believe they would downgrade on that part. I guess I will wait for the m5 and see what happens.
