Question: Will this sight be on the same plane as an A2 upper reciever?
Document: So, I want an A2 front sight post to use with a carry handle rear sight.First off, this is for a regular height gas-block, not a rail height gas block, and I don't see anywhere that denotes this crucial measurement differentiation.Secondly, for A2 front sights there is a post that is adjustable up and down so you can zero to your target.
The frame around the A2 post of the sight is so narrow the sight adjustment tool does not fit inside to adjust the A2 post up/down. I have attempted to adjust with 3 different sight adjustment tools. Seller did ship quick and product was received much sooner than expected.http://www.amazon.com/gp/product/B004P7PBGW/ref=cm_cr_rev_prod_title
Shipped fast, fit and finish are perfect on my dpms upper. My gas block rail is lower than my flat top upper, so the low profile sight doesn't work. This one is perfect. Zero ed the gun, and have removed the sights several times, always holds the zero after re attaching.
Sight mounts solid on my panther arms Oracle. The front sight post itself is a little low in the mount itself so I had to move it up above the plane of the base. At the range both the handle carry sight and this post provide a 1 inch pattern at 25 m.
These function as well as standard A2 front posts, I use this to shoot Irons out to ~500 yards with my M16 replica with this mounted on my JP adjustable gas block(gas block height)
Sight is of good quality, my only complaint was the huge knob. I bought a 10-32 nylon lock nut from Lowes and washer, trimmed the bolt off by about a centimeter and instantly am very happy with it now. This is a perfect match for the mil spec rear flip up sight. It is supposed to be mounted as a same plane sight so make sure your rail front is the same height as the rear sight..
Only issue that I had was it loosened up after about 50 rounds fired, otherwise no problems with the sight
I received the sight (frame) but the sight post and pin are no where to be found. Very very disappointed.
Sight would not adjust, must be the spring under the post.Would not recommend under any circumstances. Don't waste your money.
Described exactly as it is. Works nicely. Good quality. It was a pleasure doing business for this sight and not afraid to recommend.
Answer: yes
