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

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.

I think it would..... I put it on a red lion front sight for my keltec sub 2000 and it works perfectly. Couldn't ask for a better sight post especially at night

I have a Magpul MOE handgaurd on mine and it fit perfectly. If you have a standard A2 front sight/ gas block the rear pin must be driven out and replaced with the supplied screw to mount the rail correctly and securely.

Since it fastens down on the barrel using the front sight post I am going to have to say no it will not work.

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.

As long as the sight is a standard A2 post this tool will work. S&W website states the 15-22 has a A2 front sight post. Please note "I purchased this tool". It is a very light weight material, prongs will bend easily. Its good if you dont plan to use it much.

Yes it will. I have used mine in 9mm, .357, 40S&W; and 45 ACP barrels. Make sure you have a snug fit and it will work fine.

Does anyone know if I need a 1" or a 1/2" riser to use this on a A2 AR-15 front sight? Thanks

Yes, the rear sight will line up properly with an A2 front sight post on your set up. Even though I have these sights on a 15-22, I tested the rear sight on my AR15 (M&P15X; - has the fixed A2 front sight post) in order to answer this question.

Yes, well depending if your front sight is snug tightly enough on your barrel. It will work just fine.

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

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

Well it opens up to just under an inch. So if your front sight post is no more than that. I think you shall be fine.

I would say yes, if you have the short barrel...I believe its the 18.5 inch. If you have the 28 inch barrel, probably not going to work for you.

his sight has a height of approx. 1.38" to top of post. I say approximaely because this will depend on adjusted height. Use this on a rail or rail height gas block, NOT the normal height gas block. This will work with any flat top with any standard rear sight. There will be a problem using it with an A1 or A2 upper receiver as the post height will be approximately 0.30" that that on a non F-marked sight base. Not a major deal as long as you are aware and can make adjustments.
