So I picked up a mossberg 500 combo deal from Big 5 about a month ago. Took it to an indoor range and put 40 rds of slugs through it, no problem. I go to BCSP today, put about 250 target loads, about 60 00buck, and 25 slugs through it. The during last remaining rounds, the pin for the forend fell out, both of them. The forend grip was loose from the rods. It was impossible to find them through the mix of casings, shells, dirt and rocks so we gave up. Turns out the synthetic forend cracked, allowing the rods to come loose. I remember another member lost one, but I lost both, and the forend is cracked. Is there a replacement part that uses the lug system rather than the one-piece forend deal? More importantly, would it fit snugly over my mag tube?
