[efrenbmxrider]

did you made it full automatic??

[Duckhunterbow]

@efrenbmxrider No, doing this just smooths out the trigger pull.

i have read that doing this to mil spec metle surfaces will cause them to fail in time. not sure how long but its the coating on it that you are filing away and that weakens the mettle causing it to fail. is this a problem. id like to try this on my gritty trigger. thanks good vid.

[Duckhunterbow]

@mjmoto72 It's not a problem. Normally the metal surfaces that rub on each other in triggers are not coated. They need to be smooth and polished to preform well.

Thank you for the great informative video this one with a couple of others gave me the balls to fine tune my stock dpms trigger and hammer and then I bent the springs to decrease the pull poundage. Fuck all theses u tube police who hide behind there keyboards.Anyone can turn up the volume and hear this fine. I get so tired of these fuckheads with there bonehead comments on my channel also. keep up the great work bro and thanks.....

[Duckhunterbow]

@mannexx111 Thanks man. I'm sure most of the people bitching on here don't even have an AR and most of them that are self proclaimed experts on how to make a video, don't even have any uploads on their channels.... Anyways, how did your trigger turn out?

[CTKix]

@ktulu32live Agreed. I often forget about that as all my AR's I own, I built. No warranty, but so much fun (and I just do my own repair). Breaking in is also very important. I often don't touch my trigger until I have at least 1,000 rounds down range.

[ktulu32live]

@CTKix Yeah personally I like the factory trigger in my bushmaster but everyone has different tastes. I have a few friends that swear by the match grade triggers but there is also a big difference between wanting a match grade rifle and wanting a service rifle. I had the chance to adjust the travel on mine but its not even broke in yet so Im going to wait and see where it goes on its own. Ive also been burned on warrantees because i did things on my own but if it works for you thats awesome.

@ktulu32live I have a rifle with an adjustable trigger - a pricey one at that. Guess how much I've adjusted it? Once. Never touched the feature again and I shoot the rifle regularly and have for years. I can work my AR trigger, gradually, to just the pull I want. Works like a charm. If I make a mistake, I can replace the part for a few dollars and still have a hundred fifty left over. Worth buying if someone doesn't have the skills to do their own. I'm far more hands on.

[ktulu32live]

@CTKix Those triggers are adjustable and well worth the money. If you take too much off a trigger you cant put it back. Most after market triggers are fully adjustable. Saving money is great and all but some things are worth buying.

[ktulu32live]

I did basically this same thing to a .40 auto a while back and it worked great but it was just because I wasnt patient enough for the gun to break in on its own. Ultimately this will shorten the life of the trigger because its basically forcing the weapon to break in faster than it would have naturally. Personally from now on I would rather just buy an after market trigger with tension and travel adjustment capability. Awesome weapon duckhunter, rock on.

[ktulu32live]

@TexasStraightShooter Youre right about that. It takes a lot of "polishing" to remove that much metal , but it doesnt take much sanding at all. He isnt using a buffer pad or a polish cloth , he is using sandpaper and I have seen many triggers ruined that way. To each their own, if you are very careful you can get away with it but I personally would rather deal with a heavy trigger than worry about it failing alltogether. But like I said, its not my rifle and if he likes it more power to him.

[DevLcL]

You should redo this video so that we can actually hear what your saying.

[TexasStraightShooter]

@trickykwoo2

You have to remove 10 to 15 thousandths of an inch to remove that, and when you are only polishing and removing tool marks, you are not removing much of anything-- it would take a lot of polishing to remove 3 thousandths.

[MrSchpankme]

Your going to make your object (trigger) concave by sanding it on that soft rubber block; best to put your sanding paper on a flat hard surface.

Just completed an Ar 15 build lower I have a problem with the trigger group.When I fire it and hold back the trigger no problem when I stage the trigger it fires another round.I think it's the sear but am not sure
