Will it work with a 20 inch barrel with an A2 front sight?

Yes it will work your point of impact at 300 yards will be similar to your point of impact at 25 yards this is why you are supposed to zero this sight with a certain sized silhouette target at 25 yards search m4 25 yard zero target

[ have a2 inch barrel and it fits perfectly I would guess a 6 inch will fit but the 6 inch will be exposed.

As long as your barrel has nothing on the end of it but the small brass bead sight, it will work. But if your specific model has a barrel with a rib running down the top or a tall A-frame type front sight, it will not work.

I measured the two slots where the brackets go through the ribs to attach the mount to the barrel and you can check to see if it will work. The slots are 3/8" wide or 1 centimeter. 2 3/8" from front of front slot to front of rear slot or 6 centimeters, or the center of the slots are the same measurement. Hope this helps!

No I don't see any reason why it wouldn't work. As long as you have an A2 front sight it should work.

If your barrel is not over a 1in it should work. It will fit overs my heavy barrel

I'm not sure how it would work, finding a mount for my 303 was hard as the barrel and stock seem to be different than any other I've seen. I tried 3 different setups till I found one that worked for me.

I'm not 100% sure as mine doesn't have a front sight. I removed it for a 12" handguard. It does raise the scope to a natural comfortable shooting height for me though.

Sorry, but that's a question for a gunsmith or Class 3 Distributor. Mine went on a 20" barrel.

I installed this on a flat top A4 with the A2 fixed front sights and it works perfectly for me. Hope this helps.

If the SCAR 16S front sight is like the A2 sight on an AR-15, then yes, it should work. I have seen some posts (by doing a Bing search) which say that the tool does also work on SCAR 16S sights.

Yes, it will. The frames are the same, barrel size is the only difference to my knowledge.

Yes I strongly believe it will, you will likely need to purchase a rear sight removal tool for the stock Sight. It is worth it in my opinion.

Yes it will, I have an A2 on my Ar and it works just fine. But I placed mine on the upper recevier it self instead of the quad rail. But other than that it's more of a tactical scope rather than a distance scope. So if your going for distance I'll say don't get it. But if your going for tactical and great looks then yes get it.

Yep that's what I have it on. F mark is the standard front sight. This will be the right height.

Yes I think it will work with a 20" bar. I haven't done it but the vertical rails are adjustable.

I have a 20" barrel, A2 fixed stock AR with a huge 50mm Nikon and it fits fine
