Default sport trigger

Mine cracks over @ 108 oz. on my old rcbs pull gauge.
About 6.75 lbs. It doesn't feel like it, must be all the excitement during my zombie killing scenarios !

I've tested other types of rifles up to 7 lbs.

That is about right. A lot of shooters get into a bad habits like slapping the trigger on every shot. They then think custom triggers costing hundreds of dollars will stop that from happening.

I need to get a trigger pull gauge. I've been experimenting with my trigger, going by feel.

On my built AR, I've carefully polished the sear & disconnect. I've also installed a set of JP Enterprises "yellow" reduced power springs.

I've pulled the trigger on my 15-Sport (untouched stock trigger) and my built AR. The built AR's trigger feels lighter & less gritty. There's just a little take up (is that what is called creep?), then it breaks clean. Since I don't have a gauge, I can't quantify it.

I'm very tempted to try out an ALG Defense Combat Trigger (ACT).

Yup! Been there. I'm not ready to drop the dough on a Super Semi-automatic 2-stage combat Geissele trigger yet. That trigger alone is 1/3 the cost of my 15-22 or AR build. LOL. I'll buy one if I ever buy a "top-tier" AR or build one from so called "top tier" parts.

ALG Defense was started by Amy Geissle & offers a more affordable single stage combat trigger. I'm real curious to see how good it actually is.

Check out the ALG Defense ACT trigger. The company is owned by Geissele's wife, and the triggers are engineered by Geissele. They're only $65, and they provide a smoother version of the standard AR trigger. It's made for people that want a better trigger, while not compromising safety in a standard working environment.

I am considering just polishing up some of the parts of my stock trigger to get rid of the little bit of gritty that I feel. I am also hoping that after use it will smooth up on its own.....and yes MPDC that is what is refered to as "creep" my old mausers had about a half a mile of it!!! Timney and Bold triggers are wonderful replacements for Mausers!!

JaPes asked about the "creep", I was quoting his post. I define creep as movement ocurring AFTER initial resistance that

With credit to Mr. Bennett at the Firearms Forum.........
The sear engagement in a simple hammer and sear trigger system is a narrow notch usually on the hammer. The sear is held into that notch which measures in the 10 of thousandths of an inch, by the sear spring with the engagement angles such that the sear tends to stay engaged. A correct trigger has those angles such that the hammer must move ever so slightly farther to the rear to release. No matter what happens before or after, the motion of the trigger to move the sear off that hammer notch is commonly termed creep. All trigger systems must have enough creep (sear engagement in the hammer) to assure the gun is safe. Trigger jobs minimize the creep but can not or should not eliminate it as the gun would be totally unsafe if the creep was zero. A small amount of creep is not normally felt by the shooter.

As to what is pre-travel and what is creep, in the technical sense only the motion of the trigger to move the sear out of engagement when the sear drags across the hammer notch is "travel" or creep. The motion before the sear starts to move is pre-travel and the motion after the hammer falls is over-travel. Good single stage triggers minimize these two phases of the trigger pull.

Two stage triggers usually have lots of creep but with a low force level and a silky smooth feel required to move the trigger to the break point. Close to that break point in the trigger travel, an additional force is added, which is easily felt, to get the hammer to fall. Some of these two stage trigger have spring loaded protrusion that provide the extra force. Some, mostly military triggers, change the leverage ratio when the sear is about to break to get the extra force so you can recognize the break point is near.

I have seen trigger systems where the sear engagement surfaces are so highly polished or even chrome plated such that the creep was long but the action during that phase so smooth as to make you believe the trigger had no creep at all. The problem with that is that the break point is almost random to the feel of the trigger pull and such a trigger is exceedingly smooth but hard to control.

Thank You Very Much When a day goes by and I haven't felt like I learned anything, I almost consider it a waste. I always thought that the take up was creep but I am wrong. I really do appreciate this post, like I said I learned something today!! I would hate to polish it up to the point where you couldnt feel the creep come up (the resistance change) but I think the pretravel could be a little smoother. IMHO
