Hope to get some range time shortly.
I used a new KAC rear sight, along with a AimPoint that is zero'ed on another rifle. The rear sight, while centered, was perfectly aligned with the AimPoint. I then used an "in chamber" laser bore sight. Dead on for windage, elevation was off due to the distance and sight to bore offset.How did you determine there is no cant to the FSB? Just visually? Let us know how much windage your sights need after you zero it. I'm just curious because my PSA upper needs quite a bit of windage yet visually the FSB doesn't look off at all.
I knew I would hear that. So, I rolled the dice, bought a PSA, and now I'm having to eat crow.As critical as youve been of PSA, Im surprised you went this route. My limited experience with them has been very positive. Good luck.
Glad to see you are happy with your purchase.I knew I would hear that. So, I rolled the dice, bought a PSA, and now I'm having to eat crow.
I do believe, if you have cared to follow any of my posts, I admit when I am wrong. In this case, I shelled out some cash to make a point.
The point is, if this PSA shoots as well as it looks thus far, it can be an acceptable light use carbine.
The threads on my PSA upper appeared to have been greased with motor oil. When I pulled it apart to fix the canted FSB, I fixed that problem.Well, I could not leave well enough alone. Installed a DD Omega X FSP 12.0 rail assy.
Discovered a few things.
-PSA used taper pins
-PSA parked under the front sight base.
-PSA did NOT use a molybdenum compound on the receiver threads. There was evidence of galling from the nut on the receiver.
-PSA did tighten the nut properly, it broke at 62 ftlbs.
-The PSA upper receiver is stamped "M4" in the same location as Colt receivers.
**More pics tomorrow
When I reassembled, I used to proper molyb' compound, step torqued to 60.The threads on my PSA upper appeared to have been greased with motor oil. When I pulled it apart to fix the canted FSB, I fixed that problem.
Would expect that kind of accuracy, doubt it is possible with the current trigger. I do have an LMT two stage that may find it's way in at a later date.Hopefully yours gives you accuracy in line with what my PSA upper does NOW (<1.25MOA with good ammo) and not what it did when I first got it (>=4MOA with good ammo).
