SPF to m4fun
I have a GMP upper that I am looking to sell to fund another build. My eyesight isn’t what it used to be, so the build will have a magnified optic. I don’t want to mount a magnified optic in the GMP, so I decided it would be best to sell it to someone that would get more use out of it.
I bought the upper used, but the round count doesn’t look to be too high as the shell deflector doesn’t look that marked up.
When I bought it, it had a national match front sight post which was too small for my liking. I replaced it with one of the posts that has a ball shape on top, but I can change them out or included the thinner post. I bought it without the Spikes bolt carrier, but I can provide a BCG.
Prices shipped CONUS:
As pictured with the DD 1.5 rear sight
BCM mod 4 charging handle
BCG (one of the bolt carriers LaRue sold years ago, they were not marked. I never used it in a different rifle, so it is practically new).
$535
Or
With no charging handle, no rear sight, no BCG
$405
Feel free to make offers, the worse I can say is no.
Trades:
ACOG (TA-33 or TA-11)
1-6 or maybe 1-4 optics



Here is the front sight post I installed.
