M4 colt carbine high cap. Magazine drum style

[jluhm]

I'm wondering about availability of drum style magazine with higher than 30 round capacity. Does anyone know if one is available? I'm also curious about an aftermarket ejcction port cover. Can't get original one to work and it never did work right since purchasing my m4 new. Talked to umarex and they said they were waiting for a shipment from Germany and to check back in 2 weeks.

Black Dog Machine has or had one.

What is wrong with your dust cover?

It would not stay closed, I called umarex and they sent me a new latch mech. But it would not stay together. I assembled it exactly as in drawings. I'm thinking it is slightly bent. I bought display model rifle maybe it was damaged while handled by customers or something.I think it stayed closed about 3 times after I got it home. I'm wondering if someone makes an aftermarket one to fit? I'm hoping they will warranty this as I've only had it 8 months, but I'm not willing to send it in and be without it over this. Otherwise this is a really nice rifle. Thanks for any info or advice!

When I get home from work tonight, I will see if an AR dust cover is the same as the Colt's. I'll get back to ya.

My Colt/Umarex dust cover only remained latched a few times after I bought it. This was an issue with early production but was rectified later in it's production run.

Yours is probably a very early gun.

An annoyance, granted, but that's about all.

An AR15 dust cover is very similar, but the latch is different from the Colt/Umarex. The dust cover on my Colt has always worked just fine.

All of my 5.56 covers worked fine......My Colt Umarex dust cover would occasionally stick closed and I had to use a thin bladed knife to gently pry it loose.....The little block in the center of the door was catching on the back of the bolt so I used a fine jeweler's file to round the block so as to prevent it from catching.

No more problems........
