The only problem with the OP gun is it is gas block mounted, so a no go on mbus front on the block. This set would be my choice IF I had not already bought what I have on there now.http://www.midwestindustriesinc.com/index.cfm?fuseaction=category.display&category_ID=362
Like it has been stated MI, YHM, Troy, all make great products. I MIGHT go to the cuyahoga falls gun show in the morning to see if I can sell a few things I have and find a MI sight.
OK this one flips down, better LOL! all day long...Uses allen head bolts no pins. http://www.cgwgun.com/Iron-BUIS-Sights/ARMS-AR15-Gas-Block__ARMS-41-B.aspx
Or get this to replace the gas block and it solves the front sight problem? http://www.midwayusa.com/product/410205/doublestar-a2-front-sight-gas-block-with-bayonet-lug-ar-15-lr-308-625-inside-diameter-steel-matte or this one http://palmettostatearmory.com/index.php/ar-15-a2-front-sight-gas-block-with-bayonet-lug.html
My choice would be the MI it is made for the dpms gas block height difference. Like I said it will be on my oracle when I can sell the mbus I have now and get the MI instead.
Here is another nice option LOL! We could do this all day long ya know.. http://www.midwayusa.com/product/454763/yankee-hill-machine-flip-up-front-sight-gas-block-height-ar-15-lr-308-steel-matte?cm_vc=subv12344177563
My pick if i could sell my front mbus is gonna be this. http://www.midwayusa.com/Product/2344177563/midwest-industries-flip-up-front-sight-gas-block-height-ar-15-aluminum
I know it throws lots of people off. Kinda like byntar is meanie on here. I been off line for a bit but still play mw3 and some black ops. might get black ops 2 still not crazy about it.
Just ordered some of the crkt knives they are still listed as being on woot in stock picked up three of them. They also have a cold steel knife listed on there but to big for what I would use for edc.
Still new to the site under 30 posts its 120 min thing. I'll be around most of the day will check in for the pm. Its my oldest boys b-day, so not looking good for friday but maybe this weekend?
Mbus rear is fine. The front will melt or so I've been warned. Check out the midwest industries sight its taller http://www.midwestindustriesinc.com/index.cfm?fuseaction=category.display&category_ID=79. Or add a rail like i did.
I went ahead and ordered one of these rails just waiting on it to show up. From what they said it might be a few weeks. http://www.midwestindustriesinc.com/index.cfm?fuseaction=category.display&category_ID=430
Pulled the front mbus sight since it is 1. 3/16 inch lower then the rail for the rear sight is. 2. was warned that mounting a plastic front sight right to the gas block will cause it to melt. I have since ordered a quad rail to replace the plastic handguard just waiting on it to come in when it does I will mount the mbus on that.
