I have done a bit of searching, and PK Firearms was mentioned many times in older posts for sourcing an A2 upper receiver with M4 feed ramps, but I don't see them listed on their site anymore. I'm looking for one of these uppers to go along with a 16" BCM M4 barrel I already have. Yes I know I can use an upper without, and yes I know I can cut my own if need be, but I'd rather not go that route. I would prefer one that is a complete upper so I don't have to source all of the pieces for the sight.

Also would take a C7 upper with M4 feedramps.

I didn't see any listed on gunbroker currently that have M4 feedramps, but I will keep an eye out.

He is expensive all the way around but he usually has that hard to find part I need to complete my project & I don't care to pay a little more to get that hard to find part I need. He usually has several A2's listed but I read the listing & it says " I have several of these for auction. I also have these in black as well". Shoot him a email & I pretty sure he can help you. Hit him up on that shipping, he shipped my stuff free.

Does it have m4 ramps?



I'm wondering if you sent the barrel and the upper to ADCO if they could get the feed ramps machined in?

They dremel them, specialized armament is the only one I know that does it properly, I have 3 colt a2 uppers I was thinking about sending to SA to cut the ramps, then send them to victor at us anodizing to have them re-anodized current production colt black, then sell 2 to pay for the project.

Colt also does the feedramps after anodizing if they have to on uppers and they leave them exposed.

I have a Colt A2 upper that has M4 ramps.

Colt 6520 carbine uppers used to have M4 ramps

I've actually been on the hunt for a 6520 at normal price for a while. All of them on GB are $2k or so, and don't seem to be moving. They were $900 3 years ago.

I still want a 14.5", but if I got the 6520 I could send it to Adco.

there's one 6520 upper for sale on the EE

M4 feed ramps....you can get the M4 feed ramp extension from brownnell's for the barrel

Yes small Drem tool can make your small ramps on the receiver part.

What are you talking about? M4 feed ramps are 2 part, they are machined into the receiver. An m4 barrel extension without an m4 upper is going to give you the same effect as a riffle extension.
Guys please do some research before we spread incorrect info around.

I've been looking at this one for a while for a retro-ish carbine build. The listing explicitly states M4 Ramps.

Not to highjack but how are these guys? Trustworthy? I've been looking all over for one that was not Bushy, or RRA.
