I should have an NEA DMR rifle waiting for me when I get home. Looking for suggestions on accessories and optics to turn it into a slick unit. So far looking at a Magpul PRS stock and the rest is up in the air. Price isn't much of an issue so I am open to all suggestions.
 
If you're using higher powered optics, I would look at getting an extended charging handle as it's a bit difficult to operate one with a scope in the way. BCM Gunfighter Mod 3 or 4 would be my personal suggestion.
 
I've been dying to make a DMR build ever since I've seen this one.

But for the most part get a Geiselle trigger, PRS stock as you mentioned, bipod, and for optics..... I used a Bushnell 6500 at it is beast. Lastly if you have the equipment, skills and time, I'd suggest finding a stainless barrel for your AR. This isn't quite my department so you'll need to talk to ATRS or another CGN member that can guide you on this part.

Oh did I mention, you want precision? Gotta do your own reloads.
 
The Atlas Accu-Shot Bipods from Wolverine seem to be on a lot of guys' builds... I'll probably get one myself sooner or later.

A good scope would be good with a good mount, the Vortex or ADM mounts are really good for the money, (relative to the scope)... maybe some 45 degree offset iron sights just to be cool... but for sure a Gieselle trigger! Think that's a must on any DMR
 
I like the looks of the nightforce 2.5-10x. No paralax adjustment though. Sightron has a 3.5-10. Larger objective lens and no zero stop though. For a DMR build i would go with something along those lines and load up some 77gr SMK's.

Update the trigger, switch out the 6-position stock with a solid A2 style, bipod of choice, then scope of choice.
For my DMR project, I was thinking of getting a Vortex 6-24x, but I think I'll get a max of 6 or 8x, to keep things realistic, within budget, and moreso like a traditional military DMR.
 
I'm assuming that by "DMR rifle", you are looking to set up a better than average AR from the accuracy standpoint.
A good trigger is a start. The aftermarket ones will make a difference. Wil you be shooting it in competitions? If so, be careful; there might be minimum allowed trigger weights, and many aftermarket triggers are too light. Factory triggers can be worked over.
Also, if you are going to compete, check if bipods are allowed.
I would sugest a good brake. Really enhances shooting performance if any double taps or rapid fire is to be done.
You will want a quality scope with easy to make, repeatable adjustments for windage and elevation. Parallax adjustment is nice, but may not be necessary. It is easy to put a too big scope on top of an AR. This makes it top heavy and contributes little.
There are all sorts of good scopes, with attractive power ranges, made by Leupold. Korth, the Leupold distributor, can install target turrets on any that are not factory equipped with them. There are other makes and models of scopes that are just as good. The sky is the limit if your pockets are deep enough.
Remember that tackiekewl doesn't necessarily equal enhanced precision shooting performance. Put your money into things that will materially contribute to shooting effectiveness.
Good ammunition makes a difference. Bulk 55gr ball is fine for CQB, not so much for longer range precision shooting.
I don't know if the barrels that NEA puts in its DMR rifles are selected or tested in any particular manner to insure precision shooting. In any rifle, the quality of the barrel is the bottom line in accuracy.
 
In its product description it's mentioned several time that the PRS stock is a replacement for A1/A2 fixed stocks. Does that mean it won't work with my NEA? It comes with an M4 style collapsible stock. I am new to the AR scene...
 
The A2 and M4 use different buffer tubes, springs and buffers.
Does the stock come with the buffer tube assembly?

Length adjustment on the M4 can be useful for fitting the rifle to you. I would suggest that you shoot it first, see how well it shoots, before starting to swap out parts and assemblies.
 
Really? The only thing DMR about that Rifle is the 18" Barrel.
I would have picked a higher quality unit to start a DMR project.

First thing is to go over that rifle. Make sure it is built properly.
Reading the reviews here does not give alot of confidence.


But if you must. A trigger from Geiselle trigger would be a good step.

A Compensator next.

Make sure you post pics of how your build goes.


When I decided to build a DMR style unit, I started with the most important part. The barrel, a Stainless Noveske.
Then went from there with high quality components from Proven Manufacturers. Companies that start up over a few months don;t have a track record to be trusted.
 
why do you have to sh!t on the OP for his rifle choice? he already has it so why not just accept the fact and move on?

get a good trigger or just a spring kit.

the stock is a commercial 6 position, so i if/when you swap it for a PRS, you need a rifle length buffer.

a good comp is more important than a flash hider.

start with a decent scope 4-12/16 is good. don't know about your ranges, but around here 200m is about max for me 99% of the time.

a good bipod and a modpod for the stick as well.
 

Nice build, mine's starting to look a lot like that, but, I'll be running slick handguards, in an attempt to keep weight down. I'm trying to source some Daniel Defense MRF 12" or Troy Alpha/Bravo 12" rails... they're just a little scarce right now it seems.

I'm debating of the stock (for myself at least)... not sure if I want the PRS or the UBR... just have a standard collapsible stock, though maybe I'll keep it simple with an A2 fixed stock, I think those are still relatively inexpensive?

@liquid_1477 how's the weight on that puppy anyways?

When I was looking for a stock for my DMR project, I intially decided to go with a PRS stock, but then an A2 stock came up on the EE for a hell of a deal, so I picked that up and saved myself close to $40.
 
I realize the NEA may not be the perfect platform but it's what I have. If the AR bug bites maybe I will start sinking serious money into some bigger name rifles. Still lots of good info, I can't wait to get home and start putting it all together!

There is nothing wrong with the NEA, its just that a lot of users here give them a hard time because of QA issues and other issues that have come along with the company. I have an NEA lower for my DMR starting point, and I think its going to be a great base to work off of.

Price isn't much of an issue so I am open to all suggestions.

NEA and "Open Budget" do not belong together. If the OP want to stick with NEA then I am sure it will be great, if he does not roll a lemon. 18" does not make it a DMR anymore than a 20" makes something a "sniper rifle".

Start with your barrel, decide if you need to worry about competition restrictions (bi/mono pod) and think real hard on selling the NEA just so you can move upto .308 and really reach out.
