WOLFF - AR15/M16 TRIGGER FUNCTION PAK

Quick shipping and a good price. Worked just like advertised.

An easy install with no fitting. I reduced my trigger pull weight by 1-1/2 pounds with no polishing

Have used these on a few lowers. I start out with a Critical Capabilities LPK with ELG trigger. Pull weight is reduced and with some polishing on the trigger and hammer engagement surfaces I was able to get a very nice smooth pull between 4.5 and 6 lbs, (avg 5.25 lbs) with no loss of reliability on hard primers.,

I've used two sets of these springs and they make a very noticeable light and smooth difference in my two ar15s. I will be ordering several more.

I have used a lot of Wolff springs, but always in cowboy shooting guns. Some made a lot of difference, some a little, while others could be made equally well with original parts and some tuning. This is one case to just save your money, as little as they cost to begin with. Actually, save yourself the aggravation of R&R the hammer spring just to get to this. I took seven readings before doing a thing. They varied from7.5 to 6.75 lbs of pull; mostly 7.5. After going through the whole mess, then lubing everything again, I got the same readings. Mostly 7.5 lbs. What a disappointment!! The worst part of it all is that this was replacing a spring out of a DPMS lower parts kit, so pretty bottom of the barrel to begin with. OTOH, the included disconnector spring seems to tighter. It is definitely a little shorter though; not by much.
