M&P 15 Sport questions

Great to hear it. Sounds silly but, keep it stock untill you put a hundred rounds through it, just for the experience.

^^This, irons don't run on batteries. Therefore they always work! Make sure you can use them before you start adding dots and scopes.
 
i always wanted an ar15 but just couldnt afford one....until the mp15 sport came out. i love mine and the extra money i saved was used for accessories and ammo etc. my brother special ordered a RRA for twice what my sport cost and he has been waiting for 3 months. ive been shooting mine for 3 months and have it decked out with cool aftermarket goodies...and my brother will have to wait another 3 months to save up for accessories. yeah i guess you coould say i got the brains in the family:cool:
 
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.

Thanks for the excellent info; I've searched and might have overlooked, but what is the range for 223/556 grain bullets for the 1:8 twist on the Sport? I wrote down 55-68 but not sure where I found that. I ask because locally there is a ton of 45 and 50 grain 223 but not much 62-68 and hardly anything in 5.56.
 
I have a question for you guys now that I got my optic installed. What was this weapon actually zeroed for from the factory? I grouped ok, but was mostly using Kentucky Windage to adjust and I figure I should set it up for 50 yds as that'll get me .36 inches high at 200 yds and 1.47 low at 25 yds. All of which are acceptable when you think about where your shot should land...take a ruler to your COM and you'll see what I mean. So again, what was the factory zero? Or is there one?

For 1:8 twist, general guidelines are 40 grain and up. Each individual barrel is different though, so you may find that yours does not handle the 40 well. The 50 grain should not be an issue. Typically, I can find the 55 or 62 grain .223 locally, and fairly cheap. Most of the 5.56 is FMJ and is not allowed at my range. Once you get over 68 grain, the rounds become expensive and not necessary for plinking at 100 yards. But the Sport should handle up to at least the 80 grain without a problem.

Mine was good at 50 yards from factory. I adjusted windage a couple of clicks, but nothing on elevation.

Cool, I may have been at 50 yds when I tested it out the first time. I don't even know as we didn't have anything measured. I'll take it up to the state range and do some known distance shooting to confirm that and dial in the dot. But the way, the UTG Red/Green on a cantilever mount is a really nice low priced option...as long as it works when I shoot with it.;)
 
I can't remember who it is. Someone on this forum put a standard AR receiver on his 15-Sport. It's pretty cool. If I didn't build an AR with a FA & dust cover, I'd be real tempted to try it on my 15-Sport.
 
Well I got my Sport a little over a week ago, fixing to start customizing it. I guess I need to at least shoot it first, I ain't been able to make it to the range yet.

Hey that $683 AR will do everything that the $1500 AR will but with more money left for ammo and goodies. No shame in it, no regrets about it!
 
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?

Its a great ar15. I have one. You can attach a rail system on it and attach any accessory u want. You can do whatever you want to it. It is a cheaper ar15 because it has no dust cover or foward assist. But your arent at war so who cares? I shoot mine outdoors where it is windy and sandy, and I have only had 2 faillures to feed. But that was because of the mag
 
That has to be the funniest misconception in today's times, just because a object cost more doesn't mean its better quality all the time.

I can't tell you how many times I have looked at things and seen name brands that were poorly made and higher cost and lesser known brands that had great quality and lower cost.

You got that right! So we Sport owners are the lucky ones! We got name brand, well made, for a good price. What more could you want?
 
thank you for the info sir! the 50/55gr *is* a lot easier to find versus what I was thinking the 1:8 needed.
 
I recently bought an M&P 15 (811000) for $830 + shipping on Gunbroker. Sounds like I should have shopped around and gotten a "Sport" for much less.

Are their any advantages to the more expensive version I bought or is the $500 extra asking price just wasted money?
