after assembly was there any problems firing the weapon?

BEST ANSWER: Absolutely not. I honestly couldn’t find for certain what the blem was. I concluded that it was the slight ringing in the finish on the barrel where the front sight was installed. Mine has seen hundreds of rounds, flawless.

Quality Product and I still don't know why it was a blem...
Quality Product and I still don't know why it was a blem kit. The does it's work with heavier weight projectiles but loses a bit of accuracy when you get to 55gr projectiles. Would easily buy this again.

Definitely worth it
To call this a blem is almost unfair. Perfect function and honestly I scratched my head for a while trying to figure out what the blemish was. The only think I could come up with was a small “ring pattern” on the barrel from where the front sight post marred the finish on install. You would never notice unless you knew it was there and looking for it. Great rifle kit.

Fast Shipping, Decent quality
Seems to be of good quality except the bolt carrier is rough looking. Shipping was quick. I intend to buy more items from PSA, but may use the bcg that comes with it as a spare.
