So, I finally got all my PSA parts in today and assembled. PSA MOE upper and lower, 16" stainless barrel.

I currently have no plans to use it with open sights, going to mount a scope and run it that way for awhile.....or forever.....so, do I.......

1. Leave front sight on and by rings or mount to clear front sight and leave front sight there.

2. Get a low profile gas block and swap with my current block.

3. Leave current gas block on and cut top of sight off.:eek:

Scope I was planning to use is a 2-7 Redfield I have sitting on the shelf. Will that work or do you have other recommendations?
 
I don't like option 1 as that will mess with cheek weld and at the very least be awkward I think. Option 2 is probably the best, but there is no reason option 3 can't work if you are careful and want to save a few bucks.
 
A mount that centers the optic 1.5" above the top of the reciever will work just fine with the front sight post in place. This is close to the same effective height of the iron sights, so cheek weld will not suffer. Plus you should have enough room to mount a rear BUIS if you desire.

This is essentially the same set up as any .mil carbine issued today, a set up with over a decade of proven use by dudes that kick doors down and shoot savages in the face.
 
You pretty well layed out your options. The only others I can think of are a folding front sight base, or a railed one with a folding sight on top. I favor a low profile gas block under a free float handguard. I have chopped down a front sight base to make a low pro gas block for such a setup. It works fine, but in hindsight I don't think the time and labor is worth it when you can get aftermarket low pro GBs for $20-30.

It is true that most one piece mounts are at least 1.5 inches high, which is enough to keep the front sight post out of the center of the field of view. I'm sure this is probably why most companies make them that high. Most shooters don't know what a cheek weld is, and instead do something like a "cheek touch," and so aren't bothered by the optic being that high.

I personally like an actual cheek weld, with the entire weight of my head resting on the stock with a completely relaxed neck. It makes for a more stable position with less muscle tremor and allows you to comfortably remain in position longer, especially in prone. It is also helps with consistency.

Anyway all my scoped ARs use a YHM extended picatinny riser and low 30mm rings for perfect cheek weld, and have some form of folding front sight.

I cut my front sight off. it was harder than I thought it would be. I'm running midway's ar stoner mount. No complaints. It's made by warne. If I had a few bucks more though, I would get the aero precision mount.
 
Going to "test drive" my friends currently un-used M-223 mount this weekend.
 
Cut the front sight. If you take your time it will look fine and be very secure.


I like Warne, ADM and bobro mounts.
 
The other option I didn't see mentioned is leave the front sight alone in case you ever want to use it in the future.

It is too close to the scope to even see it, except at very low power.

Even then it will just be a ghost image and not that bothersome.

With almost any sight above 1x the front post will disappear like the nose in front of your face. You might notice a little ghosting at 2x but it will disappear an any reasonable magnification.

Do a search on Google for "scope with front sight base" to see the experience of others.

The shooter may not "see" the FSB, but it's still there, blocking the scope.

If it were me, I'd cut the FSB but cutting metal is something I do professionally and I enjoy DYI projects.

The Redfield 2-7x is a good choice to for a beginner scope. Install it and shoot it until you either decide it'll work or decide you want something else
 
Vortex 2-7x32 in a Promag el cheapo mount.

I have no scope interrupting my line of sight even on 2x.
It allows me to use my irons via quick release detachment.

Just mounted the M-223 and the scope that was in it.

Have the option to get the mount and the scope too if I want it.

Keep this scope (Nikon Prostaff 3-9x40) or use my Redfield 2-7x33?

Also found a Nikon Buckmasters 4.5-14x40 I forgot I had.

Reckon that would be to much for the new AR?
