Bigger AR type rifle

[FC]

Completely agree to a point. 

No offense but from what I've seen, John is putting together a pretty nice rifle. Throwing a ghetto trigger in it with a slower lock time just seems like a waste of time 

I've done a LOT of the 15 minute trigger jobs. 

I've done a LOT of things that I regret too! 

The only problem I've had is they tend to not have enough snap to set off some of the harder military or sometimes even Remington primers. 

Strong evidence of the slowed lock time you get from cutting that spring, you won't likely have any other problems per se but you will absolutely not have as accurate of a rifle as you could have with a proper trigger with a full power hammer spring.

Could you use an Aluminum hammer in an AR?  Just thinking less mass to accelerate would equal faster lock time.

I really don't see why it would be a waste of time.  It is not the best by any means but it does no harm to the gun and at most it costs less than $5 to replace the springs if you don't like it.  John's gun is awesome and i agree at some time a nice trigger would be awesome in that setup.  Sometimes though it is hard to pony all the cash up front to get a gun setup exactly how you want it. Personally my trigger was so bad that I could not get decent groups since the pull was so heavy. So I did the ghetto trigger and it helped and now have very nice groups and was able to shoot my gun much more since I did put the money into being setup for reloading for this gun.

I don't think you can get aluminum hard enough to last more than a very few shots. If you look at all the better hammers they all have a fairly thin post leading to an enlarged head with as much of their weight as possible concentrating the force of the strike on the firing pin contact surface. Even with the enlarged head they are still quite light weight.

@coop, I well understand not having the dough to get a rifle setup how you like right away but I've also seen a lot of guys do just as you have and never replace the trigger since they haven't experienced a good one.

fwiw, if you can do your own AR trigger that is anything close to a RRA NM trigger than you should be doing them for a living 

The Geissele and Timney are both awesome triggers although I have doubts about the Timney lasting due to it being single stage.

Just did a search on this and I got this link.  Decent info.

Just shoot it as is for a couple of weeks or whatever it takes you to buy a good trigger, you will crap your pants at how much easier to shoot it will be after you swap it!

I cant wait to crap my pants!

You will probably cut your groups in size by half.

We shall see! That will be the first upgrade I get for it when I can swing it.

any grendel guys in NW wa? ( near bellingham? !

[JohnVH]

well, as my luck is, this thing doesnt like any of the two boxes of hornady stuff, have to force the bolt to close all the way, have not shot it yet as at the range it wouldnt close enough to work. Calling Bill Alexander tomorrow, then seeing where to go from here.

If the bolt won't close on a factory round then the barrel isn't chambered right, did you see that it wasn't closing or try did you try and fire it?

[JohnVH]

went to the range and tried to fire it, CLICK, I was like, wtf, pulled it back and no ding on the primer, tried another, same thing, after examining at home I realized the issue. not obvious if it doesnt close all the way on these things.  Ive heard that early hornady stuff had some sizing issues, wondering if I got some of that bad batch.  Thats why I was wondering if there were any grendel guys close that I could try another brand of ammo...

[FC]

Did you verify that your firing pin was in place and undamaged?

[JohnVH]

yep, when the bolt is closed it sticks out enough, at the range I never got it closed enough.

Just checkin', I've seen a few guys who had a problem with their rifle not going off and after much drama finally figured out that they had left the firing pin out.
