Could use some help with my AR build project UPDATED w/addl question about ADCO
EDIT: OK, so I'm aware I need to have it sent off to ADCO for drilling/pinning.
My question I have is their site states the following:
Install Your FSB we pin your FSB in place $90.00
You supply the FSB and we pin it in place with 2 barrel pins. We do NOT install FSBs on any surface coated/hardened barrel.
I haven't done anything with the barrel, but I'm sure it has some sort of coating on it. How do I know??
ORIGINAL QUESTION:
I'm trying to surprise the GF with a Xmas gift and this is my first attempt at a build.
I've ordered the parts from Surplus Ammo and Arms, PSA, and Brownells.
I'm working on the upper/barrel assembly currently and haven't had any issues up to this point.
However, I'm stuck on mounting the A2 front sight/gas block.
I'm confused how the darn thing actually mounts to the barrel.
My guess is I've got the wrong part, but I thought I'd run it past the folks here first.
This is the front sight/gas block I ordered.
This is the upper assembly I ordered from Surplus Ammo and Arms.
Here are the photos I took. Note that the barrel has no holes in it to pin the front sight. The only hole is for the gas tube.
I'm confused, but I'm betting I've got a case of the stupid and ordered incompatible parts.
