They are "top tier" and good-to-go. Excellent QA/QC program. Paul puts out superlative products. As said, a little pricey but "buy once.....cry once".

If you plan on running a carbine hard, consider Bravo Company. I have seen carbines with improperly staked carrier keys, cheap bolts, and low quality triggers fail during prolonged firing schedules at classes.

Speaking for myself, I will spend the extra money for piece of mind.
