I asked this question in general ar discussion but didn't really get much help. Hoping maybe this section will be better.
Rifle is a 14.5" pinned midlength 5.45x39. Right now it has a Magpul MOE with MVG on it. I personally like the more solid feel of a metal setup with a grip but never had a problem with the MOE/MVG combo on my old upper. I am focusing more on weight and see that the Midwest 2 piece drop in rail is only half an ounce heavier than what I currently have. Is this worth the money for the improved accuracy/possible improved reliability? |

I put free float tubes on mine. I have a couple without them but the guns I shoot the most have them.
Just shooting off hand there probably isn't much different. Start using a sling to build a good solid firing position and it can make a difference. Start resting the forend on something to make the rifle steady and it can make a difference. Want to mount a light on your rifle and it can be easier with the right type of free float tube. |
| I free float all my barrels because it assures that the accuracy is the best it can be with that barrel. Ammo makes a big difference in accuracy also. With the barrel free floated there is nothing touching it to change it's POA. And I have always seen a positive change in the accuracy ie smaller groups down range. My latest rifle is a DPMS LR 308 and with standard carbine handguards it would shoot 1 - 2 MOA at 100 yards. Once I free floated the barrel I'm getting 1 to .5 MOA groups at 100 yards. |

Ordinarily I'd say that free floating is worth it, but for your particular application I have to go against the grain here and say no.
I'm not the know-all authority on the 5.45 round, but it seems to me the appeal of the round is the cheap commie surplus ammo that's out there. You're not going to make 4 MOA ammo do 2 MOA by free floating the barrel it shoots from. Maybe someone with a greater knowledge base on the 5.45 will correct me if I'm in the wrong. |
| If you are trying to shoot 16 inch diameter target plates at 300 yards and beyond then you want to free float. If you are planning to shoot CQB 50-100 yards and doesn't require tight patterns then you can do away not free floating. It just helps for accuracy work. |
