Delrin is probably your best choice. Lots of guys build their high speed bolts from Delrin [I think that's what my A5 has]Fwiw.. I'm not sure how long the o-rings are going to last [I see two locations that are suspect]. The one on the end of the 'prong' that goes down the center and the first oring from the right end of the bolt. They both are 'interupted contact' in operation. In my experiance.. anything like that lasts about two cycles before it dies.. but then maybe I'm missing something?
