So I put together a lower for the first time last night with a trigger I’d been using in another lower. I used Wilson lpk and a Wilson flat wire spring with an h2 buffer. How many rounds should I run through it and how should I go about it to make sure it cycles correctly?
The upper has been getting used with an h buffer and was completely reliable. It’s a 556 setup, and 77gr at 2503fps.
