ICS M4 & KJW 1911 MEU upgrades.
 

So I was wondering if anyone has suggestions for my ICS M4. I'm looking to get it upgraded. Same for my KJW 1911.

My ICS m4 likes to misfeed BBs. Idk if its the hopup or just the King arms mags I have. I'm really just looking for accuracy, not FPS.

Same with my 1911. I want accuracy, not FPS.

Any suggestions would be great seeing as I don't know what to start with.

Most likely mags and the hop-up rubber that might be worn.

ICS usually feed really well...

Hmm, possibly might be the hop-up rubber. Or the mags, maybe I'll just get a new hop up rubber. What mags would you suggest? I heard King arms were pretty good. But thats what I have right now. So idk where the problem is. I bought the m4 a year ago from someone on ASC but he fucked my over with so many problems with the m4.

I personally like chineses metal M4s... they are about 8$ each and feed well.
One batch I had to modify the BB retainer (take the mag appart and remove a molded stop), but they still work A1 now.

I would start with the hop-up rubber. The stock ICS one is not the best there is...

Suggestion for the hop-up rubber then? I'm ordering from airsoftparts.ca.
