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:

I put a double hook FCG in my sar-1 and the difference is like night and day. No more trigger slap and way better trigger pull. Fairly new to AKs so I can just speak from my experience. The extra slot is easy to put in with just a small round file the same size as the existing slot.
Your post illustrates why double-hook FCG's are superior. Arsenal has begun putting single hook FCG's in its SLR101 series, probably because K-VAR thought it was going to be stuck with a bunch of inventory when Century announced it was going to stop importing SAR's.

The genuine newly manufactured Arsenal SA M7's all use double hook triggers, but I guess since Arsenal converts the SLR101's from single-stack guns they thought they could get away with installing single-hook triggers . They probably think that the SLR101's are not part of their "premium line".

I can't argue with their wanting to use up excess parts inventory, but being that the single hook triggers are not as smooth as double hook triggers, I think they are taking a chance on creating an impression that they are starting to skimp on quality.

A lot of companies have premium product lines and economy product lines, but in my opinion, if they consider the SLR101's to be economy grade, then their pricing should be closer to that of a Romanian SAR than the premium grade SA M7.
