So my local gun shop wants to charge me 60 bucks to shave down my front site base.  What do I need and how hard is it to do myself?  I own a dremel tool.  Is it worth it to avoid the hassle and give this man 60 bucks?

Thanks and be safe!

I did mine on an LMT once.  It's not all that difficult.  Why on earth would you pay $60 to have an FSB shaved when you can buy a low profile gas block for way less than that?

Check out the Build It Yourself Forum.  There is a tacked thread that illustrates how to do it.

Cos I don't want a gas block which is held in by set screws.

If you're somewhat skilled weith a Dremel, it should take about 20 minutes total.

Don't worry about doing it fast...take your time and do it right.

You can make things easier by using a bench vice to hold the FSB, and don't forget the safety glasses.

Wow that section is quite informative.  Do I have to remove the front sight base in order to shave it down?  Or can I leave it on the barrel?
Also, that guide states to spray paint the thing when I'm done.  Should I do this or apply some type of bluing?

You can cut it faster with a sharp hacksaw than with a dremel. Then, pull out the files and smooth it over. Burns a few calories, too.

I did mine on the rifle, but only because that barrel had a pinned/welded muzzle brake.  It would definitely be easier to remove it and put it in a vice like Mark mentioned.

I spray painted mine with high temp black Krylon.  No issues.

I've done a couple this way––After using the files ,I like to use the dremel with a sanding drum to blend in the radiuses(sic)

I cut the top off the base with a hacksaw and then used my bench grinder to smooth the edges down.
When I was done it looked exactly like the factory one on a bushmaster ORC.

Spend th $60 on tools and do it yourself.

Buy an armorers wrench to pull the barrel, FSB bench block and taper pin punch to remove the FSB.

One the FSB is off, hacksaw, small belt sander or dremel & black BBQ paint.

I actually borrowed the bench block and punch from my local SO armorer.

It's very easy to do and you don't need to buy any special tools to do it. Depending on how picky you are about the looks, you don't even have to remove it from the barrel or use anything other then your dremel with a few cut off disks and the sanding drum. I put a little more effort into mine ('cause I like things purty! ) but it really is as simple of a job as you want to make it...

Airgunner, that is a work of art! I'm going to have a rail over it so I don't think I'll need it to be that pretty.

if you get someone else to do it, send it to ADCO. otherwise just do it yourself.

+1 for do it yourself, the pins gave me a bit of grief but the end product was good and the $$ went toward the free float tube.

+ this is what I did, I didnt make mine too pretty because I knew my rails were going to cover it. I cut it to fit them then painted over them, wouldnt be that hard to make it look good though! I wouldnt pay $60 for it.
