RRD-4C 14F KeyMo

Written by Aaron on Feb 26th 2020

The part looked well machined and designed, but also aesthetically pleasing. It is being placed on a build I am having completed. Once I get it back I will update and give impressions on how it handles.

RRD4C 14F is amazing quality

Written by Zachary Alexander on Feb 22nd 2020

Absolutely love the quality and functionality of this RRD4C 14F comp. Not only is it one of the best brakes/comps on the market, but one of the best if not THE best "Dead Air" suppressor host on the market! Thanks Jmac Customs for the quality products and the great customer service you have provided as well. Ashley has responded to every email/question i have had and in a timely manner! 5 STARS for sure! Already recommending Jmac products to my friends/family!
