AR-15 Light Strikes Please help!

[bronsonb1]

Ok guys here is what I am dealing with. I built my AR about a year ago with a JD lower and Delton everything else. After doing a trigger job a few months ago (I copied the job done on the AGI video, the trigger feels so great!) I have been getting light strikes with PMC Bronze ammo and Federal black box 223. With Federal law enforcement grade ammo however, my gun was functioning flawlessly. I would like to avoid doing any more mods to the trigger becuase I love where it is at. But I cannot accept these light strikes, I want my gun to be very reliable with all ammo. If you have any advice or experience with this sort of thing I would greatly appreciate it if you would share that with me.

Thanks,

hammer spring tension was changed because of your mod.
swap to different hammer spring and test again.
springs are cheap and you need to go from light to standard weight.
trimming leg on hammer spring can be unreliable (light strikes) if too much is taken off.
some primers are harder than others and require more force. hammer spring.

Spring was put correct way in? You using a bulletbutton that runs through hammer pin?

If you cut the trigger spring, you might need to bob the hammer (cut the spur off of the end) to regain some of the inertia lost due to the lighter spring. I have a few rifles done with the 15 minute trigger job, had issues with light strikes until I bobbed the hammers on all of them. More like a "30 minute trigger job" now.

Another issue you might have is if you took to much material off when making the sear face less positive. If thats the case it will cause the hammer to sit more forward than its intended position causing less striking force when the sear releases hammer. Lite strikes is a common sympton in general with most types of triggers when the faces had a little to much material removed. One stroke is all it takes to go to far.

also check your firing pin protrusion

Make sure you didn't put in the hammer spring incorrectly. If that doesn't help, try a full power spring.

Thank you all for the replys! I finally had a chance to tear the lower apart this morning and I did put the hammer spring on backwards lol. That was probably the problem. Hopefully I will be able to take it out sometime soon to verify that it was indeed that which caused the light strikes.
Now my trigger is still light, but after correctly installing the hammer spring it has become more gritty feeling. Any tips to smooth that out would be appreciated.

Don't mean to be a smart arse but buy a drop in trigger. I've never been a fan of modifying the stock trigger. Just too much frustration and to much possibility of fouling something up beyond repair.

I know a drop in trigger is not cheep but it is money well spent. and you won't be disapointed.

Start simple.

It worked before, then you performed a trigger job, now no worky worky 100%.

I'd start w/ NEW hammer spring = cheapest and easiest 1st attempt to fix.

YMMV - good luck!

Is hammer spring installed the correct way? Easy to install upside down by accident
