Best SBR upper, and best customer service and shipping!!

by -

This is going to be a two part review. I'll start with the item. Being in the military I grew up using the MK-18. I own one myself. This upper though is definitely an improvement. Between the improved dwell time, recoil impulse, and the extra real-estate on the handguard I have to say that this is a much better system. Not to mention that I love Mlok. Not much more to say about Daniel Defense they know what they are doing.

The next review goes to primary arms. They have earned themselves a new customer for a long time. Not only does their website update in real time but the customer service is awesome. The shipping is exactly what they say it is which I am very impressed with.
