Anyone polished their AR FCG?

[Jakashh]

Saw these at what seems like not too bad a price. My factory A2 trigger on the DD sucks horribly, wondering if i should grab me one of these. Don't feel like bothering messing with my own.

Polished Mil-Spec Fire Control Group ? Ground Zero Precision

Are you just trying to get rid of that gritty feel, or trying to reduce weight? I was going to break out the dremel and polish the factory trigger parts, but then I read around and found that polishing will perhaps make it a little more smooth, but the weight won't be any different since that is controlled by the springs. I just went and bought a new one since I wanted a lighter weight.

might try a set of the JP springs....$11 or $12

I use a Dremel to polish all kinds of firearms parts. Feed ramps, triggers, etc. I use Flitz as the agent and a variety of cotton wheel and tips from Dremel. Its not hard

The springs sounds like a cheap enough idea to try.

I have done the polish job on my AR. It smoothed it up a bit, but that's all. Still had a bit of creep and a pull of 7 1/2 lbs. So, I installed a Wolff reduced power trigger spring and disconnector spring. That dropped the pull to an average 6.50-6.75 lbs. About a one pound improvement. I left the original hammer spring, as I didn't want to increase the possibility of light primer strikes.

It's still not the way I want it, so I have an ALG Defense (QMS) trigger on the way. I don't really want it lighter, just crisper. I don't know how they compare to the Ground Zero triggers, but ALG has good reviews.

the trigger group is probably out of spec on that DD. Get a mil-spec Spikes unit.

Polish, bob the hammer, throw in some JP yellow springs and do the set screw pretravel adjustment and you can make a killer single stage out of a milspec trigger group.

I might have to try that kit.....I'm a bit timid to try it on my own, and ice got a couple I'd really like to clean up.

JP AR trigger springs

JP - Spring Kits

JP Reduced Power Spring Kit This spring kit will yield a 4.0-4.5 lb. pull with standard AR-15 trigger parts and 3.0-3.5 lb. with JP trigger parts. Application: Use of this spring kit requires the use of US-manufactured (domestic) ammunition or reloads with domestic (non-NATO spec) primers as ignition reliability will be reduced with hard, low-sensitivity primers such as those found in NATO-spec and various foreign-manufactured ammunitions. These springs are for recreational or competition shooting only and should not be installed in any rifle used for defense or duty applications or any AR-10 type rifle.

yep, them springs are winners...

Are the springs really that bad with nato rounds? Will replacing everything but the hammer spring make a noticeable difference?

I changed the springs out on my milspec trigger and it lightened it up considerably, but I did do both the hammer & trigger springs, takes 2 minutes. Plus I did a little polishing

 

[jparks54]

Im just worried that changing the hammer spring will make it less reliable with nato rounds as thats all i have.

they are kinda a "can't loose" kinda thing. They only cost $11 -$13 so yer not out much if you don't like em. Can always go back to what ya had. I know a few others really liked em.
