RPK Handguard retainer

[skx762]

Where would be a good place to look for a lower handguard retainer. I need one for my .308 Saiga and read that only an RPKs will fit without heavy mods. I'm used to looking for AK parts and didn't notice how few RPK specific pieces there are until I tried searching for this piece. TIA

K VAR did have some of the square bottomed ones like the Bulgarian Polymer RPK lower handguards use. If you are using a wood handguard, get the whole barrel assembly from Inter Ordnance for about $70. The barrels are ragged out but you could most likely get most of your money back by selling the other parts that are left.

I forgot to mention, if anyone has money to burn www.sksman.com has brand new Romanian RPK barrel assemblies for $400 (the last time I looked).
