hey guys l was just checking out the ACP site and waseondering the difference between the MR-1 DELRIN BOLT and TERMINUS BOLT

The delrin bolt is a straight up thermoplastic polymer bolt, wheras the Terminus is a thermoplastic polymer bolt with an anti-chop design. Basically, when it clips a ball, it contracts the spring inside of it and does not continue forward, while the hammer continues forward, opens the valve, and produces enough air out of the valve to recock the marker. That's the theory at least.

I bought a low blow bolt from them along with a striker and so far it works great and not chopping any.
