What would be the necessary upgrades that I should perform to a new ar15 (bushmaster).  I wanted to know if there is anything specifically that would enhance performance, fix any known issues, etc... Thanks...

First mod i made was replacing the grip with one that tickled my pickle.  Ended up with a Hogue ambi grip.

I think it makes a world of difference, even if some people prefer the standard grip.

I agree, I dont like the standard grip.  I too put on a hogue.  Other than that, my ar is stock and it shoots great.hug.gif

Tune-up the shooter before tuning up the weapon:

Get some quality training.

Once your abilities exceed the rifle, then go ahead and trick it out.

Look at it this way:

If you invest in some good training, your abilities will not depend upon whatever rifle you happen to have in your hand. Having training is a universal thing, it goes with you everywhere......

Good advice and besides when you go to one of those places,theres some good ones,youll see what others have and you will get top see and maybe even shoot other guys weapons so you can see the gadgets for yourself,you will walk away with better weapons handling,experience and be able to save money on not  buying things you wont use because you will alraedy have that knowledge through your experience...priceless..in a way a course of traing will save you money in the long run and give you a good working knowledge and experience with the weapons that you carry.

PISTON UPPER. ....
HK or LMT or KKL. Dosent matter which one.

Best money I've spent was on a RRA (Rock River Arms) NM Trigger.



You can always shoot better with a good trigger.

agree with coyote3

My only upgrade would be to get a 20" govt profile, that Hbar is too heavy.

Do this, but first, get a hogue grip and a gapper.

Is that thee "Drop in" model sold through brownells? Can it be easily tuned? was it much more difficult to put in in comparison to the standard trigger assembly?

What Troy said.

Mags, either USGI 30's or if you can't find those, SA-80 mags from CMMGinc.com.  These come with chrome silicon springs and green followers tossed in.  Install the springs and followers CMMG gives you and toss the ones that came in the mags.  These mags are identical in shape to USGI 30's, but are made of steel instead of aluminum.  They function perfectly and fall free for me.  I would buy at LEAST 8-10 mags per rifle.  

A plain old ordinary GI cleaning kit, if one does not come with your rifle.

A tiny bottle of BreakFree to keep in your buttstock along with the cleaning kit, just for a rainy day.  And a 4 oz bottle (not spray can, the little black plastic bottle) of BreakFree for general cleaning and lubricating.

You can later acquire these spare parts:

Extractor, extr spring & pin, gas rings (either sets of 3 or the one piece McFarland type) get several sets, spare trigger and hammer springs and pins.  Perhaps a spare hammer and trigger, and a couple of disconnectors and springs.  A spare cam pin, firing pin, and several firing pin retainers ("hairpin").

These parts would cover 99.5% of all the parts you would ever need, and probably not need them because you have them.

A mag pouch.  I like the ones sold by www.galatiinternational.com, part number GLMP30.  No Alice gear needed, and each mag is in it's own pocket, so they don't rattle around.  $20 ea.

I buy and shoot only ammo made in the USA, Israel (Israeli Military Industries from Hansen or others), or South Africa ("battle packs").  Read that previous sentence again.  Saves listing all the brands.  55 gr FMJ (M193) is fine, and I see no need to stock up on the much more expensive M855 ("green tip" 62 gr penetrator).

KISS   "Keep it simple, Stupid!"

The only gadget I have bought that really improved my shooting is the Eotech holographic sight.  I like them so much, I have three of them now.

Where can I find the USGI or SA-80 mags for a good price?  I looked at the site suggested, however they do not take internet orders.

trigger

for mags try AMMOMAN
