I love the look of the Ruger AR-556 MPR Nato and to know it can be even used for competition.
juan c on Aug 10, 2019
Prior experience with Ruger quality, and then I researched & looked at several reviews.
Joseph B on Aug 10, 2019
I was looking for a Ruger with a little better furniture than the standard one I see all the time. this ar has most of the items I wanted & a price that is less expensive then some other rifles I checked out. The majority of the reviews were good so here I am
David C on Aug 9, 2019
I have been wanting this gun for over a year and could not pass up this deal.
Steve S on Aug 9, 2019
Great Price
Joe M on Aug 9, 2019
I chose this rifle because of the upgraded Elite 452, two stage trigger, CHF barrel with a 1:8 twist, 5R rifling, muzzle brake, and Magpul furniture. There is no other rifle on the market that offers this many upgrades for this little money. And I like the Ruger no questions asked guarantee and fantastic customer service. .
Antonio P on Aug 9, 2019
Great reviews.

feng x on Aug 8, 2019
I wanted a 223 cal or 556 and wanted something I could mount a good scope and shoot distances with a good barrel and sights. I figured I'm better off buying something better than just an average AR style rifle.
william s on Aug 8, 2019
I did a few days of research and reading. This gun gives you the best bang for the buck.
nikodimos A on Aug 8, 2019
I never had a problem with a Ruger firearm & I wanted to get a non handle ar to mount optics.

Ruger favorite maker and this is a price very hard to beat.

Fits what I wanted in a rifle.
John S on Aug 5, 2019
I use grab a gun due to good prices and quick delivery!
Richard L on Aug 4, 2019
This rifle has great upgrades from the base rifle that would cost hundreds of dollars if purchased separately.
William T on Aug 3, 2019
Great price & easy order through website. Very convenient and trouble free so far! Thank you!

The price
Danny O on Jul 24, 2019
I feel that this is a very competitive rifle right out of the box.
Gabe O on Jul 23, 2019
Looks to be a good gun for the price for not ever owning an AR before.
John V on Jul 23, 2019
After quite a bit of research both on the MPR and Grab a Gun, I could not pass up the deal. First time purchase from Grab a Gun hopefully everything will meet my expectations and go smoothly
Erick R on Jun 28, 2019
Price and Features are unbeatable
Thomas H on Jun 23, 2019
Pricing. Trusted brand previously proven through prior purchases. Quality features and furniture on MPR. Plan on setting up for mid range shooting.
John M on Jun 22, 2019
Features for the price put this ahead of the competition. Sure, the SIG M400 Tread seems nice and cool, but its more expensive and I like the handguard on this better. A name that you might trust more than something like Del-Ton but still very affordable
Russell T on Jun 19, 2019
Always wanted an AR rifle-- this is s feature filled weapon at a very good price from a brand name company
Richard E on Jun 19, 2019
Shot one. Best bang for the buck. Awesome trigger.

Larry Y on Aug 16, 2019
Is this a good and powerful enough rifle to use for hogs and deers hunting in public lands? Thanks
Thawng on Dec 31, 2018
BEST ANSWER: In my state we can’t hunt deer with this rifle but my sons both took hogs in Texas with them. We’ve killed numerous coyotes with them. I’m fully confident if your state will allow you to hunt deer with one of these rifles with a good soft point and good shot placement you won’t have any trouble taking a deer out to about 300 yards.
Does this work with the magpul mbus sights?
Georgio on Dec 10, 2018
BEST ANSWER: Should work just fine... has normal picitinny rail. If you want it to cowittness with a red dot just get the right height riser. I used a scope on mine and got the riser high enough to clear the flattened sights....
Does this Ruger MPR 556 rifle come with a case or bag?
David on Feb 27, 2019
BEST ANSWER: At the time I purchased mine it came boxed without a case. Great gun and shoots very good.
Does this gun have a Wylde chamber?
Gene on Aug 1, 2019
BEST ANSWER: No, it is not a wylde barrel but it still shoots .223/5.56. This gun has an excellent barrel. It is a steel at this price. Also has excellent trigger.
Does it come with open sights?
Arthur on Aug 15, 2019
BEST ANSWER: This particular model does NOT come with any sights. The top is basically covered in rail so you can add whatever optics or iron sights you wish.
What is the twist rate?
Cale on Aug 8, 2019
BEST ANSWER: This model has a 1:8" rate of twist.

Good shooter. Decent trigger

Straight shooter. No fluff!
Ruger put all your money in everything that counts. Magpul sl stock. Ruger improved trigger which, unless you shoot competitions, is a heck of an improvement over mil spec. Picatinny/ M-lock front end. 18” bbl. Straght shooter!
Where Ruger didnt spend your money. No Unobtanium coatings. Keep it dry or oiled. Ruger stock bolt carrier and upper. Solid with no fluff.
I have 300+ rounds through it with no issues

Nice gun-- great trigger- loud-- but no real recoil!
Just shot the gun for the first time today-- used Winchester 556 ammo-- it apparently doesn't like Winchester ammo as I had 3 jams-- one ending my shooting session as the bullet was "stuck" in the gun and the charging handle would not budge. ( had to take the lower receiver completely off from the upper to free the round) I am blaming the ammo as I see some small dents in many of the rounds-- next time I fire it, it will be with different ammo- trying PMC X-tac green tip-- so here's hoping that it was just the ammo
The gun makes a lot of noise with the 55 Winchester round-- but really NO recoil that is noticeable-- (though heavy ammonia smell with the Winchester round)-- will update after the next time at the range

Great gun!
Better than expected. Best budget AR on the market. Lightweight, light trigger, virtually no recoil, and have 1k rounds through it with no issues.

Great rifle
Excellent rifle for the price. It has a great trigger and balance. It fires .223 and 5.56 NATO ammo equally well with no problems. It was extremely accurate out of the box.

If you want a quality AR at a good price.
Excellent rifle. Came with all the upgrades I would have put on it. Trigger is amazing. Light gun. Had to center the m lok rail but took 5 minutes. GAG comes through again with a great product at lowest price.
