ar occasionally not reseting trigger

[cofi]

Went shooting yesterday shot about 500 rounds twice I had an issue with the trigger not resetting and a live round was chambered.... my rifles got about 15,000 rounds on it so I'm sure something is needing replacement

I actually had a spent primer laying in my trigger group once that prevented mine from resetting every so many rounds!

^^^ a good place to start Ian. Give it a thorough cleaning paying attention to the trigger group. A bit of crud built up on the sear surface of the hammer could do it as could crud in the disconnect or groove of the trigger. Check the condition of the sear surfaces for battering.

I'm a big fan of compressed air. If you have an air compressor, fill 'er and blow the lower receiver trigger group area out real well then finish with a very thorough cleaning.

At 15k rounds, you could be due for a set of new trigger springs too. Your disconnector spring might be weak enough to occasionally fail.

Lets do some math..... 15,000 rounds times $.50 = $7,500 spent in ammo shot through the gun

New Sd3g Gisselle trigger = $250

You have spent 30 times the cost of a new trigger in ammo alone. Replace the trigger with a new one and happily shoot another 15,000 rounds until the next one fails.

Nothing lasts forever and the service life of components vs cost of things needs to be put into perspective of the big picture.

Man, when you do the math it damn near makes you want to give up shooting. [Coffee]

Ian bumps everyone for ammo whenever we are at the range. His true cost is actually only few thousand rounds, few barn glasses (ask Jim), and some sod (due to fire... sorry Ian).

I don't mean to alarm anyone by the numbers, but it is what it is. I just find it funny that people put more value or expectations on certain things when it does not make financial sense in the big picture. The way I see it, if I shot $7,500 worth of ammo through an AR and it started to fail, I could financially justify throwing away the failed AR and simply buying a new one at that point. The gun its self is the cheapest factor in the equation at that point.

That being said, I probably shot about 25,000 rounds of .40 ammo last year though a couple of different competition pistols. Knowing how much $$$ in ammo was shot through these guns I really don't get worked up or bummed out when they have a catastrophic failure that requires replacing the whole gun. Sure I rebuild or replace what can be fixed, but I also don't whine about the cost of maintenance either. Mechanical stuff does not last forever and given the cost of ammo the expense of maintaining a firearm when you shoot tens of thousands of rounds through it each year is a drop in the bucket.

I understand the point you are trying to make but you might be going about it the wrong way. It's kind of like saying if you put $12,000 worth of gas in your truck then it might be worth putting a $3,000 engine in it when it craps out. Maybe it is worth it, maybe it isn't. Really doesn't matter how much money you spent on gas for it.

Anyhow, I am straying off topic.


I'm trying to agree with cha-lee. After 15,000 rounds there might be some repairs that need to be made. Some people will run something until it actually develops problems and then fix it. Other people, like myself, will constantly monitor the condition of their equipment and replace parts before they reach the point of failure. Either way is fine. It's just personal preference. Anything mechanical will eventually wear out. Hell, sometimes mechanical things will just fail on their own for no apparent reason. It's just the nature of the beast.

Man...no wonder I never hear complaints from the buyers of my "used" guns. I might put 500-1000 rounds a year through my favorite ones with emphasis on the might :p

I'd second (or third, fourth, whatever) the checking/replacing your springs. I forgot a spring once in a fcg and it did the same thing (only every shot not intermittent).

Must be nice. Maybe you need to work more hours. I wish I had time in my schedule to shoot that much. [Coffee]

I think I've put like..... 50 rounds through my bolt guns..... Maybe 100.... I donno.

Five rounds at a time? Like when you sighted in last time? [Coffee]

[JM Ver. 2.0]

Yep.

Hey i put in 60 hours last week...........but yeah i need to get some practice time in soon.

(Bolt guns....i put 10 rounds through my .338 in the last 2 years......I really need to get out more)

This rifle is being retired when I finish buying parts for my new one BUT I don't want to retire a broken rifle and I wasn't bitching about replacing parts if you read my post at this point I'm expecting stuff to break
Btw I've only shot steel through it @23c per round the first time it's seen brass was this year

So I contacted gissele about buying either new springs or possibly a new trigger if they didn't sell the springs separately.....even though I stated I bought the trigger 3 years ago and that it had over 15k on it they offered to send me new springs free of charge.....great guys I can't recommend them enough

This was my first "nice"ar I've never owned one long enough to think about scheduled maintenance outside of the normal stuff I replaced the buffer spring @ 10k extractor spring o ring and post every 5k thinking about it the trigger probably has 50-60k worth of dry fires on it....Lol I'm surprised it has lasted as long as it has.....what else should I be replacing before I put this rifle up?
