HERES SOME UPDATED PICS OF THE KREBS KTR-03S (SAIGA) WITH THE ACE SIDE-FOLDER MOUNTED:

My new Krebs Custom KTR-03S. Next addition is an Ace Ltd sidefolder Now my AK has an AR-15 front sight post, and my AR-15 has an AK-47 front sight post

Hello! First post here. I am curious if a Ace Ltd. "Internal receiver block" can be installed on a Krebs KTR-03S, or if the thumb safety prohibits this??? I am thinking of picking up one in the next few days, but I would like to install the Ace side folder on it using the lower profile, "Internal receiver block" and not the extended "Universal/NO Receiver Modifications Required" receiver block. I appreciate any info on this. Here is a pic of the Internal receiver block from Ace Ltd's website:
