Bought my Romeo1 in June and after only 250'ish rounds mine cracked on the right side. Never dropped, traveled in foam case, only evident damage was brass hitting optic. I've been using a 15lb recoil spring that came with my Gray Guns guide rod. I did test with a 13 and thought the 15 felt softer anyways. Seems odd, but I'm curious if I need to go back to the 13lb like the post above to keep the brass from hitting the optic?
