Hello, I am new to the forum so please excuse my ignorance, if this is in the wrong section or it is already posted I do apologize for the repitition. I just purchased my first AR, I got a Smith & Wesson M&P 15 with Full MagPul, the guy i bought it from had an ACOG so there was no BUIS on it. I have the "low pro" gas block (sorry if my verbage is incorrect), that sits slightly lower than my top picatinny rail on my quad rail handguard. I am looking for sights that sit on the gas block and will create a same-plane aperature (still with me?) But it can not be plastic or anything like that because from what I am told it would melt when fired heavily. Please if possible give me some guidance on this and let me know i am not completely off base. I can post pictures if my description is not good enough, but i fell like this is a common occurance. Please feel free to suggest any particular sights (front and back flip up included). Thank you for reading and bearing with me, I will catch on quickly.

i have a flat top s/w optics ready. did extensive research and there are 3 sets of 'same plain' iron sights. will post later today. this is a common question and needs to be a sticky. am at work and need to get a project done. magpuls will not work because the front sight will melt on the gas block. i skipped iron sights (and I love iron sights... see my signature) and run a 2x7 x32 vortex viper scope only.

What you are looking for is a "gas block height" sight. A "same plane" sight is one that is to be mounted on either your railed hanguard or a gas block of the same height as your hanguards.
As mentioned, YHM has two options for "gas block height" sights, a fixed sight for around $35 or a flip up for double that. I opted for the fixed sight on my upper, as I am using it with a mil spec'd carry handle rear sight. |

if someone can get to the archive here is my link with all the info I had on it at the time and with research. =================================================================
http://yankeehillmachine.com/store/product532.html Q.D.S. Same Plane Sight System YHM is very proud to introduce the newest addition to our product lineup. The Quick Deploy Sight System features an automatic deploy system that springs the sight up with the push of a button. Both front and rear sights lock positively in the folded and deployed positions and are made from aircraft quality aluminum and hardcoated to military specifications. The rear sight is available with either a single large peep, single small peep, or dual peep aperture. When folded the sight measures just .435 inches from the rail. The front sight mounts on the same plane as the rear and uses standard hardware. It is available with either a hooded or standard stem. When folded the sight measures just .435 inches from the rail.. ========================== Samson FFS & FRS Sight Package (Best Value) http://www.samson-mfg.com/ar-15_html/product/QF-FFS-FRS.html Samson FFS & FRS Sight Package (Best Value) Samson has recently introduced a new line of flip up front sights as well as a flip up rear BUIS. All sights are made from 6061 aluminum mil-spec hardcoat anodized for durability. All of the sights lock in both deployed and folded positions. The spring mechanism is quite durable and is completely concealed to prevent fouling from dirt. Samson QF-FRS - Flip Up Rear Sight The dual aperture rear BUIS has a conventional large and small aperture. The sight deploys with the large aperture. ================================= ================================ in the end I didnt buy buis and just went with a 2x7 scope. has been great. Decided not to buy iron sights for my first AR15 and i love iron sights. Will go with this http://swfa.com/Vortex-2-7x32-Viper-Rifle-Scope-P11227.aspx |
