Once upon a time, I bought a VFC AK-74 without the side rail, and soon regretted doing so. Therefore I purchased a 74MP rail replica for $35 dollars (hefty i know, but id rather have a proper steel one) from kalinka optics, and also a POSP.
The rail itself was rather difficult to install, mainly because of the lack of space in the mechbox. So i actually had to tap #10-32 threads on the rail itself, to mount it. The middle hole I tapped into the receiver. All the screws had to be flathead, and had to be countersunk into the receiver. Luckily, VFC did that for me for the outer two screws. Hard part was cutting down the screws to the proper length. Now its sturdy as hell. To finish, I masked off the mount and gave it a coat of paint.
Oh ya, and POSPs rule.
The first few pics are of the AK-74. The last half, AK purists, look away. I was feeling rather silly and had a good laugh.

WHAT?
MY EYES! THEY BURN!
