I ended up getting a KAC trigger, and have problems getting it set to where I want it. The first stage comes on early - about 2lbs, and then the 2nd at 4.5. Feels that the 2nd stage is crisp, but too firm. Maybe its just me, but I'd rather have the 1st stage around 3-3.5 with a lighter 2nd stage topping off at 4.5. Any input on how to tweak this? |

www.highpowerrifle.com/Stoner.htm You have the heavier of two springs that ship with the KAC trigger installed. |
| Its not designed to do what you want. Its designed to be rugged. All you can adjust for weight is the 3.5# spring in place of the 4.5# spring. You can not adjust individual amounts of pressure to each stage, over travel, etc. You can eliminate creep and swap springs... thats it. |
| The combined weight of the first and second stage will always equal the nominal weight of the installed spring, regardless how you set the screws. If you have the 4.5 pound spring installed, you can adjust the individual pressures of the trigger stages, but the total break-off weight will be 4.5 pounds. For example, if you have the first stage set to 1.5 pound the second will be 3 pounds. If you tighten the first stage to 2 pounds, the second stage will break at 2.5 pounds etc. |
Thanks for all the help guys! |

MY experience with the Knight Trigger is the same that USAMU was having. The adjustment would not remain where you put it. Plus, the trigger is not easily adjustable; if you get the weight right, the creep is wrong. Shooting service rifle and not being able to get a smooth pull even though the break is at 4.5 was inacceptable. Repeatability is also an issue. Now you can get a smooth creep if you lighten the pull considerably by about .75 lbs, but the weight is too light for SR comp and too little for combat/LE apps. I got so fed up with mine (the 3rd one after they replaced the first 2), that I got another brand . Geissele makes what I consider to be the best trigger for servive rifle at 4.5 and other for 3.5. It is drop-in, needs little if any tweaking , and is as consistent as the day is long. The USAMU is testing the trigger and my guess is most of their shooters will be using that trigger or the not-to-be-found-out-of=production Milazzo. Bill Geissele has engineered a trigger with an incredibly fast lock time; there is nothing out there like it. check it out at www.geissele.com. I have two now. You won't be sorry and the difference will amaze you. Alan |
If you still have any KAC triggers around that you don't want/need, I'll gladly relieve you of them all. How much, drop me an IM?  If this is the 2nd gen trigger with two set screws, I ain't kidding you.I've run my KAC trigger (2nd gen) for 18 months in combination with four different uppers ranging from an 11.5" shorty to an 18" SPR. The combined round count with this trigger is well above 6000, but I'm not sure how many exactly, and the setting hasn't changed one bit. I set the second stage break-off where I wanted it and used the left screw to eliminate creep, that's it. I tipped the screws with Loctite first, and since then I have had no need to touch them The trigger is damn near perfect, easily the best I've tried in any automatic rifle. I have the 3.5lb spring installed and the weight is good even with winter mittens on. Thanks for the tip on Geissele, looks pretty good. How does their system prevent the weight from changing over a course of time? Does it have a proprietary hammer or does it work with a standard hammer. What about full-auto? |
| I don't have any more Knights, I sold them all. Granted it is a good trigger if you get the right one and it works. Mine did not. Several other peole I know sing their praises and some don't. With the geissele, I've never had a problem and it is easily adjustable. It does have a proprietary hammer and this reduces standard lock(release) time by about 50%. heir screws are treatde with a proprietary polymer compound which produces a prevailing torque that keeps the adjustment screws stable. The pins for the hammer and trigger are alos proprietary with a pivot circlip that captures and prevents slop and movement. I do not think Bill has put a full auto fire control system into production yet. You may have to email him to find this info out. Take care! alan |
