Cammer said:Okay, everyone knew it had to come up sooner or later. With the group buy going on I have to ask the perpetual noob question - what is best, single or double hook FCG's? :newbie:
I have a Polish PMKMS kit and (hopefully) a Vulcan receiver on the way. I know that the Vulcan receivers are cut for a single hook, but that can be changed without too much effort, if it's an advantage. But that is really the question, isn't it?
"Better" is a relative term. The original AK-47 trigger was double hook. The only reason the single hook even exists is that when the stamped AKM was first fielded, the designers noted that the gun would occasionally fire out of battery due to excessive bolt carrier bounce when the gun was fired on full-auto. The designers added a "hammer retarder" to the right side of the trigger to slow down the hammer fall, and thus one of the hooks on the trigger had to go.
People report that single hook FCG's are more prone to trigger slap than double hook FCG's. Fit of the parts is also a factor. Trigger slap is a complex problem with as many opinions as to its origin as there are guns that suffer from it. Suffice it to say, if your receiver is cut for a double hook trigger, then you're better off with a double hook trigger. :rockin:
