Hello All,

I have a Model-1 upper (16") with an aluminum free float handguard. I think I may want to add a rail to the bottom of the guard. What risks am I running by tapping the guard and adding a rail ? Is there a better way to accomplish this (short of buying another handguard) ?

Regards,
Paul

I know there are FF handguards that are sold w/ rails on them, but usually they are pricey. Also, installation would require the removal of the front sight and any muzzle brake device. Adding a rail to the bottom would be much cheaper. But, you run the risk of the rail being in the wrong position (I think) if you ever remove the handguard. Tapping the handguard, I think, itn't any different then adding a rail to a 1911. I suppose they give 3-5 screws, depending on how long the rail is, to install. You should be fine.

I have been thinking about trying this my self. The ARMS SIR is just too expensive for just adding a few rails. Who makes just bolt on rails?

Go grab an Oly FIRSH from FAC for like $80. Its cheap and works extremely well. If you still wanna just bolt a rail on your handguard, find a local machinist, he'll charge ya $20 or wahtever to have it mounted BDC.

Thanks for the info and links. I think I will go with the rail mount to my existing guard. The FIRSH looks like more than I will need as all I intend to add is a vertical grip. Thanks Again ! -P

One thing to consider is that depending on what kind of gas block you have, you need to make sure the screws don't stick out too far into the tube. They will hit on the block when you are threading the tube back on. I had to modify my slilng stud to keep it from hitting my block because it stuck in too far.

Thats a very good point. I believe I will look for a Free Float with built on rails since they can be indexed to align the rails. The Hirsch is uncomfortable looking? I did find alot of different one's on this page. http://www.fulton-armory.com/

Try Yankee Hill Machine. They make the quad rail free float tubes that Bushmaster and DPMS sell. They have various size rails from 3" to 12". You may have to buy/customize some bolts for them though. Not sure if they come with the rails. https://secure.valinet.com/~yankeeh/cgi-bin/web_store/web_store.cgi?page=forearm.html&&cart_id=7606276_20124
