DON'T ATTEMPT THIS IF YOU ARE NOT FAMILIAR W. YOUR GUN.

 

I ASSUME NO LIABILITY IF YOU ARE A DUMBASS AND F*&^ THINGS UP.

 

IF YOU AREN'T FAMILIAR W. BASIC GUNSMITHING, TAKE YOUR GUN TO A REAL 'SMITH!

 

Ok, disclaimers done.

 

I have a 20" Bushmaster w. A2 upper that I use for iron sight practice. Very reliable, more accurate than I am w. my crappy eyes and fun to shoot.

 

However, the trigger was an abomination. Long, gritty and ~8#.

 

So I wanted to buy a new trigger for it. An RRA 2 stage match, or maybe spend some real coin on a Geissele. Then I stumbled across this: http://www.sargenthome.com/15_Minute_AR_Trigger_Job.htm and decided to do a little amateur smithing.

 

It didn't take me 15 minutes... more like 30. But I'm fairly happy w. the results.

 

The pull is now at 3.5# (plus or minus .2# on my cheapo analog gauge) A bit lighter than I wanted, but springs are cheap so I can experiment if I choose. The break is pretty crisp. I surely wouldn't call it a glass rod snapping, but it's a huge improvement over stock. The takeup is still a bit vague to me. But that could be me not being used to it.

 

I repeatedly smashed the buttstock HARD against my wood floor and the hammer did not release. I guess the next test is at the range. I'll be sure to fire one shot at a time for a while, then move up to two, then three. Results to follow.

Being that I've been accused of being nasty and bitter....LOL

 

I respectfully say I'm not crazy about the modification in that link.

 

The polishing compound doesn't really smooth out things enough and I'm dead set against cutting and bending springs.

 

Along the same lines as what you did I like to stone the hammer sear surface moderately and for $10-12 install JP springs. Going one step farther you can install a sear engagement limiting device.

 

Now this takes a little more time and a bit of skill but the cutting/bending springs... I don't get warm and fuzzy about that.

Just get JP springs. That'll improve your trigger pull a ton.

 

True to a point but you have to get rid of the grittiness too Nick. Granted some LPKs are better than others.

 

Nick have you tried my triggers? I don't remember.

IMHO, smashing the buttstock to check for the safety of the "Safety" is totally crazy! You gotta be nuts if this is your go/no-go for the effectiveness of the gun's safety.

Nope but I've swapped in an ALG and i'm gonna swap in JP springs in my other lower with the PSA LPK.

 

How you like the ALG? Is it worth it?

Don't cut the spring. Sure it FEELS nicer. But an unreliable trigger that feels good isn't worth much.

In case I wasn't clear enough, this was an experiment. I was planning on a new trigger for this gun anyway. I have several ARs. This is not a go-to gun or an HD gun in any way.

 

If this mod doesn't work, no harm - no foul!

I think it was to make sure that the hammer didn't release while cocked. If jostled hard and the hammer stays in the same place seems gtg

It's not to test the safety, it's to test that you have sufficient and safe sear engagement and is a perfectly valid test for that. Yanking on a trigger with the safety on subjects it to much more force than mortaring it would, but for accidentally tripping the sear, mortaring it is about the most obnoxious real world thing you will be doing to it. I do the mortar test with and without the safety engaged. The hammer should not trip in either circumstance IMO. OTOH I can only smash the but into the floor so hard.

I smashed it on the floor to test engagement only because my neighbors would have called the cops if they saw a man repeatedly throwing an "assault weapon" off his roof. :p

 

I'm going to get some of those JP springs that were recommended and give them a try in a new PSA lower I just built.

But that would've been more fun!! jk

 

Lighter springs are good for a lighter pull, but don't do much for feel, travel and hard Russkie primers.
