Pushrod
Master Blaster
Just finished the Bullpup build of the 870. The original kit that I purchased I wasn't really happy with and I was able to exchange it for the newer kit. The original was 25% glass impregnated polypropylene while the new kit is 30% glass filled nylon, which is much stronger and more rigid. The problems with the first kit are gone (warped parts and poor fit) and the new kit went together like a dream with perfect fit and performance. The trigger isn't bad for a bullpup, as it is a straight push metal link to the trigger, so there is very little play. The slide is a little stiff, not bad, and I think it will get better with use. The whole firearm with kit feels absolutely solid in my hands. I give it a 10 out of 10! Definetly worth the ~$350 price.
