AR Drop-IN trigger adjustment?!

[rockydog]

What the heck are these, I've built 4 ARs and I'm not understanding how this could work. Help me out here guys, do you drill the grip screw hole all the way through and the small screw in the middle hits something? by the way, this is 44.20 @ brownells.

Thanks

Look up Superior Arms lowers. They have a design that lifts the rear of the trigger close to the safety to take out the slack or creep.
That's what that will do to.
Doesn't improve the trigger, just takes out the slack (will not lighten the pull).

i wouldnt venture to give this a try at 50 bucks a pop... spend another 25 and buy a rock river two stage

Or buy a real trigger from JP Rifles

I'd either get a RRA two stage (have 3 of them and they are great) from ar15sales.com for $99 shipped or send my factory trigger to Bill Springfield for about $40.(have not used him but he gets great feedback on ar15.com) If you wanted to used this you are still going to have a heavy trigger but with less take up.

LOL Soooo, no one swears by these? I've had few nice triggers for ARs, my question is how would this work? I can't believe this works at all. I would like to see a diagram of exacty what it does. (must be the engineer in me ) How could it lighten the pull?
Thanks

looks to me like its designed to raise some pressure on the rear of the trigger shoe.... by doing this its essentially "preloading" the trigger.... not good for a number of reasons.
