M&P 15 Sport questions

[longhornfan69]

I am wanting to get an AR but don't want to break the bank and was wanting to know if the M&P 15 Sport was a decent rifle. Is it easy installing a scope or a handle under the barrel with a built in bipod or is it just entry level and there's not alot you can add on?

The only major ways a 15-Sport differs from a standard AR15 is the omission of a dust cover and forward assist. Other than those two things, the 15-Sport is compatible with all AR15 aftermarket furniture.

You can install a vertical grip and/or bipod under the standard handguards with a rail adapter. You can swap out the front handguard with whatever you'd like.

Forum member Oneyeopn has an AB arms handguard onto which he's mounted a bi-pod. I think it's this one:

He also replaced the A2 front sight/gas block assembly with a railed flat top gas block.

From what you've asked, I think the way Oneyeopn set up his 15-Sport will be up your alley. Check it out by clicking the link below:

The 15-Sport may be entry level priced, but it delivers performance beyond what its retail price point implies. I'm sure you'll be more than satisfied with it. The hard part is finding one.

It's a very good rifle. Maybe the absolute best 'bang' for the buck in the AR realm.
It will accept any AR based doo-hickey, optic, etc. you would want to add to it.

Thanks for the input, I shot my first AR over the weekend and really liked the way it shot and pretty much got hooked. I just don't know alot about them but I guess I have to start somewhere.

Boy dont let me get started:

How do I love my Sport, let me count the ways!!!!LOL

 

[oneyeopn]

These are pics I took today, I had to take the hand guard off but will be putting it back on in a couple of days. This is one prairie dog getting rifle and is way more accurate than any I have compared it against that are similar, colt and bushmaster. I would recommend this to anyone except someone heading to Iraq, and only because of no dustcover.
If you can get one you wont regret it...

Ok. Quick points on the 15-Sport as I think of them.

Melonite: A salt bath nitriding process that imparts hardness and corrosion resistance to the barrel's metal. Melonite imparts properties similar to hard chrome at a lower cost than hard chrome. The Melonite process treats the metal itself, it doesn't layer onto the metal like hard chrome.

1:8 5R Progressive Rifling:

5R Rifling info= Technology - Thompson/Center
Lands & grooves are opposite to each other leads to less projectile deformation in the barrel, lending itself to being more accurate.

1:8 = Twist rate. Normally you'll find 1:7 or 1:9 rifling. With 1:8, it lets you shoot a wider range of projectile weight. Just don't go too high or too low.

Progressive Gain = Rifling starts out loose then tightens up to 1:8 towards the muzzle. The advantage is that it's easier on the projectile as it travels through the barrel, leading to accuracy.

Direct Impingement = Hot combustion gasses are redirected via gas-tube and act directly upon the action to cycle the bolt.

Gas Piston = Not the 15-Sport. Gas Piston systems direct hot combustion gasses into a gas port/valve. The energy is then transmitted to a piston, to a rod, which then impacts the bolt to cycle the action.

The 15-Sport uses an A2 "F" marked front post sight/gas block assembly.

The 15-Sport is issued with a carbine weight buffer.

... I'll post more as I think of them. If you have any questions, just ask.

Great rifle and way more accurate than I'll ever need. No malfunctions to date with assorted brass ammo. I'm a lefty and have no issues with the function.

Added some risers, one inch rings, and a four power scope. Third shot and it was three inches high at 100 yards. I've NEVER had a rifle site in that fast before but maybe it was just luck and not the rifle.

 

[BillyJack2012]

It's an outstanding value and a great rifle. I tried to get one but the store sold it minutes before I got there. I looked for weeks to find one also. Stores can't keep them in stock. I stayed in the Smith family and got an OR. However, I'm still keeping my eyes open for a Sport locally.

You won't be disappointed owning a Sport model.

I lucked out in picking up my Sport. I went to a LGS looking to buy a Noveske N4 they had on sale. But when I got there I spent some time looking through all the ARs the store had on display and got to talking to the guy behind the counter.

We started discussing the Sport and how he felt that the lack of a FA and dust cover really weren't an issue for a non-battle rifle, and that he personally sets up all his personal ARs without a FA to reduce any protrusions off the upper...well that and the $400 savings off the N4 sold me on the Sport.

Not a single moment of buyer's regret after making that decision.

I gotta step in here. You say those weren't an issue for a "non-battle" rifle. After the testing we did with my Sport, I don't think they're an issue for a "battle" rifle either. We buried it in mud, caked on snow and mud, threw mud, dirt and other debris at it while firing and it NEVER choked once. It functioned far more reliably than the "battle" rifle I was issued from 1998 to 2002 and was more accurate as well.

No obviously, the above torturing was done with a mag inserted and the bolt forward, but hell, if the bolt was open the dust cover would be too if you had one. As for the FA, I used mine exactly 3 times while I was in. Those were when the PMI and DI said to. After that, it was clear the jam and fire. I couldn't be happier with my Sport. Get yourself good mags and decent ammo, you will be too.

Edit: I wish the video came out, but my buddy's wife was not so good with her cell phone. I'm sure there are gonna be nay sayers, but the above is no BS!

No need to call BS on this. There's a write up on a torture test done at Gunsite Academy. The Sport is definitely a winner in my book.

MY SPORT

from accuracy stand point: 5 shot group .669MOA from reloads, best so far. 2-3MOA from commercial ammo.

i'd like someone definitive - state that the sport has "progressive" (gain twist) rifling.

no failures due to rifle, several failures due to weak magazine springs.
fun to shoot as recoil is very low.

only accessories so far is:
rubber falcon ergo sure grip,
black cotton web sling, and
S&B3-12x50 scope,
burris extra high signature rings.

Phil, take your cleaning rod and a patch. put a piece of tape around the cleaning rod like a flag up by the handle. Start at the chamber end and run it down 8 inches and see how far the flag turns. then start at the muzzle end and run it into the barrel 8 inches see how much further the flag turns. You with your very own eyes will be able to see the difference. From the chamber end it appears to be about a 1-11 twist and from the muzzle end it appears to be about a 1-5 twist when you average the twist rate it becomes 1-8

I saw the video you linked. We did a side by side with my Sport and his Stag. His Stag had all the things the nay sayers condemn the Sport for not having: Chrome lined barrel, dust cover, forward assist. The point of it was supposed to be 2 rednecks couldn't jam a rifle that was supposed to be "non combat" ready.

i'll see how definitive i am.

first AR rifle

I've been a S&W guy for many years. Now own 3 M&P's .40FS,
.45c and 9mm compact. My first was and still is an old model 10. I have been wanting a Sport for a while now but they have been "out of stock" in the Dayton Ohio area for a while. I check 4 local guns shops on a weekly basis, one being a pretty big chain store. I get the same answer from everyone. Out of stock, they can't make them fast enough and one dealer told me he was told by his distributor they are on indefinite back order. I called a big store in another state and they had one. It is put on hold and I am driving 250 miles next weekend to pick it up.
I can't wait until I can get my hands on it. $699.99

 

[longhornfan69]

Well I did it!!! I finally found and ordered me a Sport, found it on GunsAmerica.com all the way in Alabama, I can't wait for it to get here, picked it up for $639.

That's what I paid at one of the "higher priced" LGS. Cost me $689.00 out the door. I found a good deal on PMags at CDNN Investments and I'm a happy boy. Sold an old .40 cal that I haven't shot in ages and that got me 1000 rounds of XM193 plus some loose 20 packs. Great for the zombies!
