    recently bought a DPMS AR im not new to the rifles just got it at a steal and wanted to know if something like this would be worth rebuilding all the internals just use the lower upper and barrel and start a quality AR build?

    Maybe upgrade the trigger and shoot it is what I would do.

    The fire group is all that comes out easily without punching out roll pins. Chalky triggers suck, swap them out. You putting In a drop in set up or a kit? I prefer a kit than a drop in.

    DPMS may not be top shelf, but there not so bad that you have strip everything and throw it away. Make sure the gas key is on tight and staked and enjoy shooting your AR.

    There is a lot of brands: Jewlell , Jp, Cmc, Geissele , Timney, almost allot the American Brands have match grade triggers. There single stage or two stage. I guess a lot comes down to preference, shooting style and purpose. I personal just use single stage match grade triggers. I do fine with them. I actually have tried the Mega Arms trigger. I like it a lot. You can adjust the creep and the over travel out of it, it is light and crisp. That is just an opinion,It might not be for everyone.

    Not necessary unless there are problems with the receiver and/or FCG.

    If you have a nasty trigger pull, first things first. Remove the FCG and clean it. Oil and lube it. Get some good oil or high quality grease on the sear surfaces and contact points. One great place to grease it is on the pins themselves.

    Reinstall it, try it out. Then if it isn't any better, dry fire it a couple hours. (just make sure the hammer doesn't hit the reciever). I like to watch Walking Dead, Game of Thrones or whatever is on the dvr. Drives my wife nuts, but it will smooth out your trigger.

    JP spring are great, the only downside is that you may have FTFs with hard primered mil spec ammo or the cheaper russian stuff. As alwasy, test it out. You can always lighten the hammer to compensate.

    Work great for me so far regardless what kind of ammo. Maybe my ARs use Spike's ST2 buffers in them.

    Lightening the hammer spring MAY cause light primer strikes on hard primers. MAY being the key word. I've run into some issues with russian steel case. (MFS 55 gr and 62 gr, wolf 55 grain) Lightening up the hammer (grinding off the tail on my bench grinder takes about 20 seconds) solves this.
