Here's a twist. You know the old Cliche' about "if it's too good to be true..." Well, if you know what you are doing, it really can be a good deal. This makes twice now that I have traded for a complete lower with an upside down hammer spring for a really really good deal. The first time I traded for one, I shot it first before noting the problem. I had about a 50/50 bang-nobang ratio. I did some switching of upper to another lower and quickly narrowed it down to the lower. So I started stripping the lower but only had to pull the hammer because I quickly realized the hammer spring was on backwards. Not going to name names but this particular ODTer seemed a little uneasy when I asked questions about function. Anyway, no big deal. I turned the spring around and bang bang bang every time thereafter.
This latest upside down hammer spring lower I traded for, I saw it and corrected it before I ever shot it. I have a suspicion that why I got such a great deal on this particular lower was because someone dumped it because of poor performance. But I do NOT believe that the member I got it from was aware and was likely just passing on a good deal having probably never fired it. I've quit caring about function on ARs. I just strip them down completely when I trade for them now and reassemble replacing or correcting anything as I do so. Everything on an AR can be replaced fairly cheap these days.
So here's the public service announcement part. Note the correct orientation of the hammer spring in this photo. If you are having light strikes with nonfired rounds but usually a dented primer, CHECK THIS FIRST! See how he spring loops UNDER and the arms lie flat? If your spring arms are looped over and angle down, then your spring is on backwards. You might want to consider flipping that around before dumping the lower on the cheap.

Are you telling me I traded you that lower too cheap? I could got more outta you? Dangit!
