I think the only mod that will require 922r compliance is the addition of a pistol grip. Or using a factory (foriegn) 8 round mag. Otherwise, it is still sporting, or in the case of using a 10 round mag it isn't deemed sporting but it also doesn't have a foriegn mag body, floorplate or follower. Same with a drum.
Your sights idea is good, but I don't know which to recommend. I'd also think the G3 sights that Tony adds would be slick!
Here's a note I just posted elsewhere ...

Does anyone have any suggestions on modifications or conversions for 3 gun?
I'd shoot it a bunch, then decide what you'd like to tweak.
Area's to work on:
Do you want it converted to a pistol grip?
Get you mags/drums reliable (if they aren't). AGP's 10 rounders are the ticket! Factory 8's are good too, but pricey. 5 round mags have thier place.
Figure out how you want to carry the mags. Vest, belt, etc. This can affect the reload style you settle on.
Find the birdshot that it likes.
Does the choke you have do what you want? Modified is a good all around choice, but getting the gun to take changeable chokes is better.
Find the buckshot that it likes.
Sight it in.
Figure out the gas settings for bird/buck/slugs.
Work on your reloads. Do you want to grind the bolt?
There are several styles of reloading, so find what you like.
Do you want a last round bolt hold open (see Jeric).
Do you want an extended mag release (again, see Jeric).
Find the stock length that works for you.
Do you need a cheek piece to get a proper sight picture?
sights are a big decision. There are a lot of options here.
Do you like VFG?
muzzle brake?
Smooth out the action, polish contact points. Especially between bolt and hammer.
Some of this stuff needs to be worked out to match the kinds of matchs you will shoot. USPSA has the only universal set of rules that I know of. Most other matches have their own thier own brand of rules. This can affect your choice of optics/sights, brakes, shot useage, etc.
Some folks have worked out a magwell, but nothing universal.
I know this isn't much help, but a lot depends on what you want and the matches you shoot.
Good Luck, it's a lot of fun!
