It's okay, but...

by Jerry68, Verified Owner from NC, United States Written on October 23, 2019
This is a decent looking upper and handguard. The psuedo-monolith idea is novel, and it seems to lock up relatively tight. The finish is good, and 3-6-9 rails are M-lok, it's pretty light, and the nut doesn't require precision alignment for the gas tube. I would have given it 5 stars, but it's a little pricy (for what it is) compared to some of the other offerings on the market. Also, due to the non-standard upper design, you cannot use most extended/enhanced bolt releases, but a standard bolt release works just fine.
Pros:
  • good lock up between receiver and rail
Cons:
  • A little pricey for what it is
Best Used for:
  • Probably PCC (I'm using it with 300BLK)
Would recommend: Yes
