So, I requested a replacement about 7 months ago and got a call about a month ago that my replacement F was in and Caracal sent me a FedEx pre-paid shipping label to send my gun in for replacement. Less than a week later I had my new F in my hands.
-Free magazine, shirt, hat, & pen.
-Free installation of a front fiber optic front sight (had to pay for the part though)
-Included a 15% discount coupon off my next Caracal purchase
-Still has a great trigger (more on this in the video below)
-Quick turnaround once I sent it in.
-Took a while for the replacement gun to get into the country; still waiting on my replacement C model
Here's the video with some shooting with the new gun, a discussion of the differences between the old and new one, and my overall thoughts of the process:
