Re: What to expect from a Tubb CWS.
Unless you have a gas block turned downed or something weird going on, yes your rifle will cycle. It will cycle better than before. Grease your carrier rails and apply a dab to your lugs. While you're doing Tubb things, run his CS buffer spring too. Then all you'll need is a Giessele trigger or another good one and your set for thousands of rounds of enjoyment.
