The concussion is bad if you are not the one shooting it. My father-in-law was about 10 feet to the left of me and said he could feel the sound hitting his face and he didn't like it. I wear electronic earmuffs all the time so the increased noise doesn't bother me. I can watch the bullets impacting the target through my scope which is impressive. I haven't tried it at 4x yet, but at 50 yards on 1x it is great. All I really feel is the bolt hitting the buffer tube and no noticable muzzle lift.
The pattern is a vector drawing about 20" x 36" of a Kryptec swatch I found on the internet. I drew it with my sign program (4 hours) and used white vinyl for my stencil. With all the different surfaces on these guns, It was the most difficult stenciling I have ever done and probably won't do it again. My Benjamin Titan Air rifle served as my practice gun and I used Krylon on it. It was much darker with more contrast. I considered darkening this paint job a bit by dusting with a little dark olive or black, but I'm afraid I'll not like it as much and with duracoat, there is no erasing.
