Archived [ARCHIVED THREAD] - Sear blocks
Posted: 7/17/2001 7:31:02 AM EDT
Does only colt have these blocks in their lower receivers?

- Colt placed pinned in blocks in their receivers for a few years - all semi-automatic Ar style receivers have some sort of sear block - usually 'extra' aluminum in the back were the sear would go in a 'normal' gun.

Not all AR lowers have a blocked area...  Only my latest Colt blue label does ( a pinned in type).  My other blue labels don't and neither do my SP1's... DIAS units fit right in with no modification.  I believe BM receivers were fully milled out also (until recently).
