Top Notch February 22, 2018
Reviewer: Customer from Houston, TX  
I've been waiting for PWS to come back out with their MK109 300 Blackout.... finally it's back again. This thing is absolutely amazing and very reliable. Easy to clean and accurate. Running it with JP silent spring heavy buffer in a PWS enhanced pistol buffer tube with a KAK shockwave stabilizer. Looks great. No issues.
