When firing my M15A4 rifle, I have a tendency to slowly pull my left hand back along the lower hand guard and rest it on the lip of the magazine well. Occasionally I will let my hand slide down and rest on the magazine itself. Being the paranoid type, I became afraid of accidentally pulling the magazine out and damaging the AEG.

I recently purchased a Picatinny rail from Blackjack Buffers (http://www.blackjackbuffers.com/) to solve this problem. It mounts to the top or bottom front hand guard. After mounting the rail I attached a vertical forward grip (thanks Bstann) and I have never had a problem again. Blackjack Buffers (http://www.blackjackbuffers.com/) carries three sizes of rail and they should fit on any M16/M4 variant with a standard front hand guard. I hope this helps you guys running into the same problem.

Here are the links to the rails:
Short Length (4.5" long) (http://www.blackjackbuffers.com/index.php?main_page=product_info&cPath=75&products_id=310)
Medium Length (6" long) (http://www.blackjackbuffers.com/index.php?main_page=product_info&cPath=75&products_id=311)
Long Length (12" long) (http://www.blackjackbuffers.com/index.php?main_page=product_info&cPath=75&products_id=389)

Just for clarification, I bought the long rail.

So unlike a full on R.I.S. hand guard unit, these individual rails just screw into the existing hand guard? I've been thinking of mods for my m4 and kind of thought that i didn't necessarily want the whole R.I.S. hand guard system, I just wanted to have one rail on the bottom to attach a vertical hand grip, this may be exactly what I was needing. How did you attach yours RW? Do you just have to start the screws carefully and drill them into the plastic? If so, how well does that stay on there?

After a second glance at my bottom handguard it doesn't appear that there are many places to screw into because of the holes that run along the bottom of the hand guard. The biggest open piece of plastic is at the end furthest from the front where there's about inch of plastic, after that there's a hole every 1/4 of an inch or so until you reach the end of the hand guard...if that makes sense. But, just looking at my bottom handguard it seems that if i screwed a rail on the bottom and held onto a vertical grip that it might try and pull the bottom guard off or something. I know the spring on the collar of a real steel gun is a lot stronger than on an airsoft replica so I'm basically just worried of either breaking/cracking the bottom of my handguard, and/or accidentally pulling it off from holding onto the vertical foregrip.

I was worried about pulling the lower hand guard off too, but I haven't had a problem. No need to drill any holes, the rail comes with the mounting hardware. It's basically a bolt and nut system, but the nut has a very large head that fits inside the lower rail. The next time you are at the field I will show you how it is installed.

Will do, if it's as solid and secure as you say it is I will definatley be getting one. If you're hitting up TXPB this weekend I think I'll be there as well, I look forward to seeing it.

If he doesn't make it I can always show you my AEG with this mod.

I did the same with my M15 tactical, but I used G36 side rails w/washers and nuts.
