Well, it's going to depend on your FF tube.
The basic idea is to use something like this... http://www.midwayusa.com/product/944060/troy-industries-32-customizable-rail-section-for-trx-free-float-tube-handguards-ar-15-aluminum-black Those rail sections are for a specific troy FF tube, but same idea. Some FF tubes are fiberglass, some are metal with and without slots. If yours is slotted, you can usually add lengths of rail quite easily. If it doesn't you could always drill it out and secure the length of rail on the backside. This type of modification is great for simple things like bipods, tac lights, etc. But not usually that good for optics or sighting equipment like NVD or lasers. Now that you explain what you want to do a little bit, I'd look at a replacement FF tube. Daniel Defense has a nice setup that gives you a continuous rail along the entire 12" length. It is the MFR 12.0 Just make sure whatever you do, verify that it will fit over a bull barrel. Too many folks fail to distinguish between bull and HBAR correctly. https://danieldefense.com/modular-float-rail-12-0.html As far as involvement, "most" free float tubes need a special proprietary tool to break or attach their respective barrel nuts. I'm not familiar with DPMS's tubes but you can probably call them and ask if they have a tool for it. As far as DD, if the MFR 12 requires a tool, they will sell one reasonably priced. I just take anything that involved to a local gunsmith and let them deal with it though. Good luck! |

Thanks another question is are all barrel nuts the same size and thread pitch? I think so on the thread pitch. Yes. Because that is the receiver barrel extension. The OD may vary depending on the FF tube or rail. Not 100% certain. Ok, check this out.... Looks like some DPMS tubes need you to screw the wrench in to the tube first. No idea if this is for YOUR tube though, but it was pretty easy to find... http://www.brownells.com/.aspx/sid=13017/pid=5595/Product/DPMS-AR-15-FREE-FLOAT-TUBE-WRENCH?utm_medium=shoppingengine&utm_source=googlebase&mc_id=10000&gdftrk=gdfV21820_a_7c187_a_7c3466_a_7c231015023_d_231015023_d_11454 I'd still contact DPMS for specifics, but good luck! |
