I have a factory DPMS Oracle 5.56 hammer spring with about 600 rounds on it.... that appears is out of spec, or weak..
I got a new spring from Brownells for like $2.. and its FLAT.. and also RED in color if that means anything at all.. but notice how one is FLAT (new one) and one is arched (old one).. granted I did the 15min trigger job and cut 1 leg abit.. which led to the light primer strikes on 1/15 rounds this last weekend.. but should (the original) it be this BENT after 600 rounds?? 
I just installed the new RED (bottom) one from Brownells and now feel even more confidant this was the issue.. what say the 'crew' was the original out of spec?? or did the CUT cause this?? |

cutting the hammer spring is what caused light primer strikes.

I thought they were supposed to be bent...
I did the 15 minute trigger job also and have had no problems 2 years later.

I don't mind it being straight or bent as long as it worked.. and it didn't work AFTER I did the mod.. I never paid it no mind when I did the mod as to how it was originally.. so I ordered the new one.. I'd rather have factory function.. over a light primer strike if SHTF.. just leaving it alone now.. its not going to be an 'accuracy gun' for me anyway per se.. |

Red spring looks like a Wolff Extra Power spring.
It works great in 5.45 ARs with milsurp ammo, but it sure increased the trigger pull. |

Is anyone elses CURVED ?? or FLAT?? |

Bent, but it's like 10 degrees from being flat.
definitely not red though

The slight bend from flat is supposed to be there on a new spring. All the Colt springs I have ever bought had it in them new. Bushmaster springs also.
Never noticed any difference in function between the two. I did not care for the 3 pack of Brownell springs I bought because of the red stuff on them that looked like paint to me. |

Wolf extra power hammer spring:
And, as others have pointed out, the light strikes are because you did the "15 minute" trigger job. |

I dont reccommend cutting the spring I do my trigger job by polishing all mating surfaces and then just bending the hammer spring like a dog leg on both legs and lubing lightly with moly cam shaft lube... Never had any problems with this nor never used ammo I couldnt ignite....

Yes. You WECSOG'ed this and added to the DPMS hate. -! |
