Tech AR question - Post 94 Colt Lower

[ralfabco]

I have a Post 1994 Colt Match Target lower. As far as I know, these have a sear block.

You need a mil-spec hammer, to work with the HK, MR 556 upper.

Can I install a mil-spec hammer with this receiver ?

Is it a large pin receiver? The hammer and trigger pins were different size.

First you need to determine:
Do you have large fire control group pins?
Do you have a sear block installed?
You can also try calling Colt to see if they will help you.
