How hard is it to remove the entire front sight, what tools needed, level of difficulty? I am very handy just have never broken and AR down past cleaning.

Are these chrome/stainless bolts any better than my factory colt bolt, will the chrome bolt just slide in and match up with my new (less than 200 round) rifle?

Thanks in advance.

The Les Baer chromed bolt carrier groups are supposed to be tops but I have never shot one.  I would not trust cheaper chromed assemblies due to chrome flaking off as has happened to some.  You should be just fine switching carrier/bolt in your rifle.

As for the sight tower you'll also need to remove the FH, etc.  Post the question at the "build it yourself" area and you should get some quick responses.

I second that,les baer chromed parts are tops I use the les baer extractors chromed they are excellent.
