I read a review on Midway as I was about to order indicating it is extremely difficult to install this with your railed gas tube? Is this accurate or was this person not doing the work properly? If you install the handguard first (and then try to install the Ultimak which I what I have) will it require modification as this review indicated?
It is meant to be paired with a drop-in, railed, gas tube, but.....to install said tube, with this handguard, is nearly impossible. The set screws, that hold it in place are angled at 45° downward, for some INSANE reason, and are UNREACHABLE, with the handguard in place, but it's impossible to install the gas tube without the handguard in place, because the gas tube blocks the handguard release latch. I had to spend hours, with a set of diamond files, carefully cutting a notch into each side of the handguard, just so I could reach the set screws with an allen key!!!!
