I found that I couldn’t group for squat with the M4 sight radius so I build it into a dissy style barrel. I milled the front sight and the sling loop legs, and then installed an Olympic Arms weaver gas block. To hold the handguard cap in place I tapped the gas tube hole and used a machine screw.
It works great and has a good balance to it. The only thing I may change is the Oly gas block and replace it with one from RRA or Armalite. Theirs has the option to install a sling loop where the Oly does not.

What'ya think?

Nice homebuild, but why is the front sight tower in the second photo on backwards? [:)]

Sure is, but I think I'm gonna keep it plain-jane for now. I'll add an Aimpoint later.

I dunno about the RRA or Armalite gas block they are highly ugly , I saw in the Brownells catalog I can get the part# if you want it, but there is an item that is a A1/A2 front sight tower with a handguard cap all built in it may be just what your looking for , unless of course you are looking for a flip up , but if you want the a-frame sight tower this may be the ticket . FYI - let me know I'll get the part# !

I like it. Was thinking of something similar myself. I was planning on getting one of these goodies from CMMG. Set screw traditional front sight. I forget the diameter on the M4 barrel. This guy is for .750 [img]http://www.cmmginc.com/cmmg_images/tbl_images/accessories_images/A2_Sight_Assembly.jpg[/img] The PRI flip ups are nice too. my $.02

Scratch the Set Screw Sight tower and get a clamp style from Armalite. Much more secure than the set screws.

Found it. Made by "HAHN PRECISION." Unfortunately it's for M4 round handguards only, wont fit 20" guards, they need a triangle cap.
