Krebs, Zenitco, Zhukov Hanguards and the SAIGA

Have a 7.62X39 SAIGA without the front end converted, and currently mounting the Zhukov (ideal mounting for SAIGA) long forend. Seems a tad heavy on the nose. Options:

Keep it and run an optic from the rear mount

Krebs Mlok which is MADE for the SAIGA

Get a steel bolt on handguard retainer and mount the Zenitco B30U system (and maybe the top rail too). Has anyone used a bolt on retainer for this system? Retainer is same dimensions, etc., but would like to see it done before I try. [Many systems bolt on anyway so why not the retainer].

Invest the time resources to get the front end converted and go Zenitco. (I could JUST have a retainer installed too - I have no press, so I'd drive an hour and have it done).

Anyone familiar with these and can comment on their employment?

Thanks.

I have a bolt on retainer on mine with a TDI lower handguard. I can't attest to it's durability as I haven't mounted a sling yet and it's just sat in the safe since install. I'm going to replace my FSB with the proper one, but just hated to touch the gas block since I'll never mount a grenade launcher on it.
