Installing FF rails with a pinned flash hider?

[Shawn L]

I need to install a DD Omega X 12.0 rail on my CMMG 14.5 upper but the flash hider is per installed to make it 16in. I have two options:

1) Have a gunsmith remove the per. installed flash hider so I can remove the front sight post, install the DD Omega and then per install another flash hider. My problem is I can't find anyone that can do this.

2) Find a way to cut off the front sight post without ruining the barrel and then install a 2 piece front sight post.

How hard is it to the the 2nd option? What tools would I need? Is there anyone in the IE that could help with either of these.

Final option would be to just try and sell the DD rails and go a different route, but I really would like to stick with them.

Thanks madmike this is what I wanted to do but I've already sent him a PM and a e-mail last week and he hasn't gotten back to me so I need to find other means.

I'm sure he'll get back to you. He has a stellar rep, and I'll be sending an upper to him myself very soon(as soon as he answers my latest PM) . I bet he's on vacation, or otherwise tied up for a few days.
There are probably lots of people that can do what you want, but personally I would go with someone that has tons of great references, even if it takes a little longer, and Randall has a huge following of satisfied customers. The times that I've been impatient (and there's been a lot of them) I've been disappointed more often than not. I have not done any business with AR15Barrels yet, so this is all based on what I've read here. Take it for what it's worth.

The quick and dirty to get the old FSP off would be to approach it very carefully with a cutoff wheel on a dremmel. Cut on the sides where it's thin, one cut per side so you don't have to do any prying etc. Then you'll still need to drift out the tapered pins. Remember to hammer those from the small side to get em out. Honestly, I'd pay to have Randall do it right by removing and reinstalling the pinned flash hider, but if you wanted to DIY it, it's not hard (though you'll probably end up with at least a nick in the parkerizing under the fsp). To reinstall your new gas block, make sure you take lots of measurements to ensure you line up the gas port in the block with the port in the barrel. I'd also recommend test firing the setup to verify before you drill the dimples for the set screws if you use a set screw type.

Hope that helps

I agree it's not hard, would just add that it's very surprising how easily a dremel cuts through the FS base that wraps around the barrel. I kept my cuts confined to just less than the width of each "band" and made only a single cut. Then used a screwdriver in the slot and gave it a little twist "like turning a screw" and the bit of metal that remained on either side snapped. The base bands are very easy to peel away from the barrel. This way, used the dremel for only one cut and if you touch the barrel at all any abrasion will be covered by the replacement block. Just my variation.

I used a YHM two piece flip type for replacement. It's all steel and stays put.
