You won't find a filler that will match when filling such a large void. You could use a filler and then paint it to look like wood if you are very good at such things but it could be scratched off and some times large patch jobs like that just fall out or crack as the wood shifts.

The best thing to do would be to find a piece of wood that matches in color (when finished) and grain, cut it to fit perfectly and then epoxy it into place.

This is difficult for even an experienced wood worker and will probably never blend perfectly although if done right will be close.

I would buy a replacement and hang on to the original.  It is VERY tough to fill and make it not noticable.  My woodworking instructor used to always say, "A true quality craftsmen is defined by how well he covers up his mistakes."

Save your time if you don't have much experience in that department and find a replacement.

If someone has replaced the thumbhole stock with a pistol-grip set, check your parts count, just to be sure.  Next, get the muzzle threaded in the correct pitch (14x1 LH).  Add a U.S. made muzzlenut (available here) and then order an ad-on underfolding bayonet.  You can get these here: Omega Arms Parts.  It's the seventh item from the top, part number is ak09.  This way, the groove in the handguard will have an actual use.  I did this to one of my MAK90s.  I even drilled the front sight for the detent, but you could just lock-tite the muzzlenut on if you'd like.  You have to use a muzzlenut to deploy the bayonet, it won't fit over a slantbrake.

If you are looking for US replacement check out Ironwood

http://www.ironwooddesigns.com/2aprod/1zAKproduct.html

Not super fast but they make a nice product.  A little sanding and staining and you will have something great.  Just make sure you get the appropriate furninture.

Quoted:I guess I may have to go the replacement route. Anyone know where unmolested lower handguards for MAK 90's can be found? I tried an extra set from a Romanian rifle but like I stated above, the MAK 90 has an irregular setup.

Thanks for that info. Your's turned out beautifully. I just have no interest in a bayonet on my AK. It would just add unwanted weight/bulk. And although the non-threaded muzzle is a dislike, I don't have the desire to cut threads on my barrel (and I'm a machinist).

I guess I may have to go the replacement route. Anyone know where unmolested lower handguards for MAK 90's can be found? I tried an extra set from a Romanian rifle but like I stated above, the MAK 90 has an irregular setup.

Threading the barrel is easy. I've done two SAR-1s by renting a kit online. Dinzag arms rents the kit if you don't have the stuff to do it. Takes about 15-20 minutes. If you already have the knowledge/tools why wouldn't you?

The 'proper' way to convert it would be with a chinese gas block with bayo lug, and chinese FSB with cleaning rod retainer. These parts are pretty much impossible to find. Most people use milled bulgarian/etc parts. They use the type I bayos, and don't have a hooded front sight, but they will retain a cleaning rod and accept at least some type of bayonet. The FSBs also have the hole drilled for the plunger pin.

The blued finish and grey charging handle are usually thought of as some of the nicer aspects of the chinese AKs. Sure, it may not be as durable if you have to drag it around a swamp, but it looks great until then.

+1!  Threading the barrel is easy, I've done lots of them.  Several of mine, several for friends of mine.  I bought the kit from KY Imports a few years ago.

I did the same mod to my MAK-90, but found the spike loop would not clear the slant brake when it was pivoting forward, so I went with a muzzle nut. How did you get yours to clear, or do you have to pull the bayonet forward to get it to clear?

Those "clamp on" spike bayonets weren't made for use with a slant flash hider.   You have to use the muzzle nut.
