PSA AR-15 16" MID-LENGTH 5.56 NATO 1/7 NITRIDE 13.5" LIGHTWEIGHT M-LOK MOE EPT RIFLE W/MBUS SIGHT SET.

I just purchased this from PSA  it came with backup sites (polymer)  my 68 year old eyes are having a hard time seeing the front site.  I have a Holosun  HE510C-GR  green dot which works great. Should I just lose the backup sites and make room for 3x  Magnifier.

No I won’t shoot it that much . It’s just a defense just in case rifle.
Looks cool next to my Beretta A300 ultimate patrol.

Funny though I can see the peep sites co witness.  Through  a Holosun  507C. On the A300

IMHO, Lose the backup sight... and the front one as well.

Your Holosun has a 50,000 hour life / battery.

And your Holsun is "probably" as durable as those back up sights.

Backup irons are pretty much optional at this point in my opinion, outside of a dedicated duty or mil rifle. You can definitely lose them.

Ok guys thanks .
Now should I get a 3x magnifier .
Or am I just making things more complicated?
But it would be fun for at the range.

Self defense rifle?

If you think your life is worth $100, buy a cheap Chinese made red dot for $100.

If you think your life is worth more, buy an Aimpoint. And the Aimpoints work great with old eyes.

In my opinion that’s the real problem. There’s an old rule that you should never change your gear unless you shot it for a 1000 rounds.

Whatever you decide to do you should shoot it for at least 1k rounds just to see if it is feasible or not. There is no way any of us would know if your setup works or not but what I can say is that if you never train for it then it’s probably more of a liability than if your gear choice is justified or not.

If you’ve got the funds, no reason not to try it. Certainly makes shooting at distance easier.

That^!

Move the Holosun to a less important rifle. I have an Aimpoint PRO and nothing else on my home defense rifle. I change the battery yearly.
Don't forget about the Trail of Beers Happy Hour!

Maybe but I had Aimpoint pro on my last rifle. I had some starburst on the red dot I like the Holosun green dot a lot better.
And I think it’s faster and works with my eyes 🤷‍♂️

The  polymer backup sites do not .

Nothing wrong with Holosun.
Your boos mean nothing, I've seen what makes you cheer

If you turn down the intensity the starburst goes away. I have bad astigmatism and can't use an eotech because of the ring of fire, but turn down the intensity on the PRO or ML2 and the red dot becomes clear. Polymer sight are fine but in low light you wont see them. The holosun is fine but it won't hold up in adverse conditions like the Aimpoint.

If you do want to keep a front sight, Blitzkrieg spike posts are damn good for those with poor or worsening vision.

Ditch the backup sights if they're little use to you.

I have astigmatism as well, and have issues with my Aimpoint comp M2.  The red dot looks like a smear to my eyes.  Sights using green dots work much better for me.  I understand green is recommended over red for old guys like us with astigmatism.

I like the Holosun green ring . Plus the field of vision and it seems to be good  quality.
Plus, I have it on my handgun and tactical shotgun so they’re familiar to me .

I took off back up sites and   Installed a Holosun 3x magnifier.
