I think you could use a tool to assemble, that will generate a consensus of forward and reverse reads, but this will depend on the length of them to has overlap. Apparently in your BLAST, consist in alignment from only one read.
You can try to assemble the 16S (Sanger sequencing) with these tools:
You can try aligning using the free tools in DNA Subway too. Make sure that one read is forward and the other is reverse to find the overlapping region.
Or you can even align them manually (old-school, but it works)!
