I have a box stock Bushmaster AR (Picture below) with the std. forearm. I want to add a quad rail forearm in its place. Couple of questions:
1. How hard is this to do? What is the process? 2. What do I need to buy in addition to the forearm? 3. What brand/type do you recommend? 4. Is this a carbine length forearm? http://www.pbase.com/nextcraze/image/104909602/original.jpg |

Yes you have a carbine gas system. You need a 7" rail system, you can go with something longer if you replace your front sight base with a low-profile gas block.
If you would rather leave it alone and just replace the handguards, I'd recommend looking at these: Non-free floating: Troy MRF-DI Free floating: DD Omega Both are very easy to install, and they are solid systems. |

Thanks for the recommendations. Two quick questions. 1. It says I can bridge optics from upper to forearm. Is this acceptable or will the optics move around enough to change point of impact? 2. Why would I want a fixed versus free floating forearm? Is the accuracy better with free floating? |

The free floating rail does not come into contact with the barrel. The logic behind it is that when the barrel gets really hot you will not be applying any unwanted pressure to it like you could with a non free floating rail. Therefore you accuracy should be better.
Damn I'm bored at work. |
