AR15: Fixed Front Sight VS Gas Block

[lovemachine]

AR15: Do you prefer a Fixed Front Sight or a Gas Block? (Shorter handguard VS longer handguard)

 

[SSGSAD]

Mine is STOCK, as are all of mine .....

Except for glass .....

 

[phylodog]

Why not both?

Which suppressor is that phylo?

Surefire Socom



I have a midlength with a fixed front sight post, so already have a longer sight radius. That being said, every other AR I have is a low pro gas block with a folding set of BUIS on them

Fixed front sight for a KISS/cause rifle. Folding BUIS on the other cause there is some sort of optic on them

Me personally I prefer a longer handgaurd with a fixed sight. Much like Phylo mentioned.

SOCOM 556RC

I've been looking for a front sight that clamps onto the barrel behind the brake, that's not a block... anybody seen a good one?

Not an AR owner:

But I much prefer the aesthetics of a low profile gas block, longer rail, and flip up sights.

But Phylo's rifle looks mighty nice also.

I thought you bought a Colt awhile back?

Nah... Can't afford it.

I do have a pile of parts that will one day transform into a 9mm pistol, but not yet.

I prefer a chopped down A2 with a longer forearm and flip up sights. That said, I don't mind an A2. My biggest thing is that gas block is attached with taper pins rather than bolts.

I like both. My walk around rifle has an A2. My DMR has flip ups. I'd prefer an A2 on a rifle that's going to get knocked around a bit. Just seems a bit more robust since there's less mechanical things to break on it.

I personally don't like looking at a sight post while I'm looking through an optic. I also am a full co-witness guy. If you prefer lower 1/3rd cowitness, that sight post isn't as much in your way, so you may not mind it being there. Because of that, if a rifle is going to have an optic, I prefer quality metal flip up sights. The extra handguard length is nice to have as well. If the rifle is going to be primarily used with iron sights, and there is nothing wrong with iron sights, then I like the sturdiness of the A2 post.

Now with all of that being said, phylodog is rocking fixed sights on an extended rail, and I'm pretty sure he is a full cowitness guy as well. So tastes do vary.

Correct. I've found that I don't see the front sight if I'm shooting both eyes open so it doesn't bother me. It's completely subjective and thankfully the AR platform allows for a wide variety of techniques. One of the reasons it's the best platform in the world (flame suit on lol)

I'm going with a 16" barrel, longer hand guard, and possibly flip up sights with red dot optics

If you've got irons of any kind mounted on a float tube instead of the barrel any torque on your tube changes your zero. That always concerns me. Either get flip ups or a tower on the gas block or just run your optic.

I've never experienced it and have been shooting free float rails for years.

I think that would depend on which handguard you're using.

I'm trying to decide how to build my next one. I have one with a dedicated scope on it. Low pro gas block, no irons at all. I am building a 16" with a 13" handguard so that will have a low pro gas block with some flip up iron sights. Maybe a red dot at some point.

Another build I am still thinking, but am leaning towards a 20" with an A2 front sight post. Ol'Huff told me if I practice I can learn how to shoot irons again so I am thinking I want to give it a go.

And my last build is still in it's infancy stage so I have no idea how I want to configure it. Maybe a MK12 knockoff?
