The hard part is aligning the components of the trigger with the slave pin and then the holes in the lower. I use an old (my grandpas) light hammer with light taps.
Normally you do not need to remove the safety. The only trigger Ive encountered that needs the safety removed is the Geissele DMR.
The KAC is not adjustable in the sense you can control the reset or anthing else. This one came out of my EMC factory set. All you are adjusting for is proper operation not like the DMR. So this KAC trigger would be plug in play in any other lower with proper pin hole spacing.
Nice video, I plan of keeping just one KAC in my inventory, the rest SD’s. Something about the KAC just makes for a fantastic general purpose trigger. The SD-C just blows it away in that same category imho. I always wonder why KAC stays with ole’ adjust(for KAC use)/nonadjust(for end user use) trigger design…turns folks off I think even though it’s not a problem unless you as the user tweek with it.
I wish my SSA-e would have been that easy. The hammer spring is a bitch, making it hard to align the hammer. I got rid of the slave pin and it was a bit easier.
Installed my SD-E last night and it was my first time messing with an AR trigger. I learned a quick lesson in what happens when you pop the pin out of the hammer/hammer spring without anything to stop it from FLYING ACROSS THE ROOM.
Then the KAC Match trigger fell into 3 different pieces (not looking forward to putting that back together).
Awesome to hear that you like it, it not only feels amazing, it’s uber reliable. I am around 7k fired on the first SD-E I got…zero hiccups…1 tube of lube expended:cool:
Funny thing, I let my brother (who is not a gun guy but was over last night after I installed it) dry fire it a few times. He looked at me and said “why don’t they make all triggers like this?”
I used to sit with my legs crossed and cradle the lower receiver. This would keep the platform stable and I could ‘finger f__’ the trigger & disconnector until the slave pin seated properly. The hammer was also ‘finger f___’ by letting it ‘cycle’ up and down until the slave pin was seated properly.
The sear was a mofo to deal with because of the spring, basically the slave pin would drive the punch out while it seated. I used to take the pistol grip off to get the safety out.
If you are taking the pistol grip off…watch for the spring that holds the detent that holds the safety…it can get lost very easily.
I had to do the above without attracting attention, hammer movements would have gotten me busted by the armorer.
Most triggers don’t require the safety to be removed. The DMR does, though. Ive never messed with any FA triggers aside from cleaning and inspection of duty guns. That 3 round burst cam sure adds a lot of parts, though…
And yeah the spring for the safety detent can be easily lost. On the EMC and SR15 both the safety detent and rear take down pin detent springs are held in by the grip which adds doubly to the probability of losing one.
Yea, I just installed an SSA. First time for me also. The trigger went in slick with the slave pin, but the hammer was a bitch. Finally found that cocking the hammer back a little bit I got the holes to align.
