Received my new M&P 15-22 Sport yesterday. It is a current promo with S&W rifle case and red dot sight. Cleaned it and sighted in the RDS today. What a great firearm! I have a couple M&P 15's in 2 calibers and they are nice in their own right. Light, accurate (1st 5 round group was .938" @ 50 yards), feels really good in the hands and reasonably priced to boot. Shot Federal Premium 36 grain HP to start. Haven't tried Mini-Mags yet.

Love ya Smith & Wesson! Well, not everything is roses. For some reason, the dot is not round and precise in the RDS - at least with my glasses. It's a 4 MOA which I expected would cover the bull at 50 yards and it did. I don't experience the oblong dot on my other, obviously more expensive RDS's but I took the chance anyway and it is what it is. Totally usable as is.

Have to figure out what purpose this little beauty has for me. You can customize it nearly as much as an AR. Scope? Better RDS? Grip? Sling? Suppressor? God it's good to live in a free state of the USA! Hope you all have as much fun as I did today.

It makes a box of ammo empty real quick and having fun doing it. How long it takes to empty a box depends how many full magazines you have.
I have to say I haven't had any jams with it.

Hi Webfarmer

I believe your problem with not seeing a perfect round dot in your rifle sight may be due to you having a slight astigmatism.

I’m a coach/instructor for a club here in the UK and we use the M&P 15-22 fitted with red-dot sights for our guest days where we give non-shooters the opportunity to have a go at our chosen sport.

We generally have anywhere between 20 and 40 people a day so we get a lot of different views (if you’ll excuse the pun).

After hearing a lot of people talk about seeing ‘flared’ dots, two or more dots, elongated dots and various combinations and variations thereof, I did a Google search and discovered it’s a common problem.

The general consensus is to ask your optician/optometrist to run a specific check for astigmatism next time you visit him/her.

Apparently, and I haven’t looked into this (pun intended) so don’t take it as gospel, using a ‘Reflex’ type red-dot sight is the solution but, as everyone’s eyes are different, only you will be able to tell by actually looking through one before buying.

Hope this helps.

I have a very pronounced astigmatism, and red dot sights are useless for me. IF I see one dot, it is in the wrong place. More likely I see multiple dots of varying size/intensity, still in the wrong place(s).

Bottom line I use iron sights or normal scopes.

I agree Iain as I do have an astigmatism. It wasn't so obvious on my better red dots. Will have to look at reflex sights but thinking of scope now. Still haven't figured out it's purpose for me other than a fun gun. Nothing wrong with that

Hi Webfarmer

Just been re-checking my facts (because the question of blurry dots came up at the range today) and I've given you the wrong info earlier in the thread.

You should be looking for a 'Prism' sight and not a reflex sight.

There's a very informative YouTube video by a guy called 'The Daily Shooter' in a video called 'Red Dot Sights and Astigmatism Blurry Dot to Clear Dot'.

I'm not sure how to put in a link to it but it should be easy enough to look up.

Apologies for the misleading info and I hope you get it sorted.

Happy shooting

Iain.S

Fun! Fun! And then more fun!

As to the dot flaring issue, I have astigmatiam and always used to turn the intensity knob on my work M4 to the “recommended” 9-10 o’clock position until I had a low light qualifying shoot and saw how much it flared. Now it sits at between 7 and 8 o’clock on all butbthe brightest days.

I ah e only just started to get into red dots on my personal firearms (my 15-22 was the first) and I turn them down to the lowest intensity to prevent the flaring.

It's easy to check if it's "your eye" or the sight.

Take the sight off rifle, and rotate it as you look
through it. If the aberration rotates with the
sight, the defect is in the sight. If the aberration
maintains it's shape/orientation, the defect is in
yer eye...

Iain, I'll check his vids for that. I am subscribed to him Thanks for the updated info!

Yeah, I did turn mine down to the lowest settings also on both red and green and the it was still there. Need to shoot it again after deer seasons are over (live on my hunting property) but can sure take it outside and try the options everybody offered without firing Thanks!
