Question

What is the difference between these two AR-15s?

I want to build another AR and I was told that the M4 will be a desirable gun in the future but I really can’t tell the deference between it and the C.A.R. other than the barrel. Can anyone tell me what makes the M4 kit worth $50 more?

As far as future investment what AR configuration do you feel will be more desirable in the future if a possible ban were instated? I already have 15 lowers and I want to build a few…or should I buy more lowers? ….heck stocks don’t make money so why not buy guns right??? Thanks for any input.

Answer 1

The CAR kits have a non-removable carry handle, a standard profile barrel,  smaller diameter handguards, and a three position collapsible stock with a flat buttplate.

The M4 kits have a removable carry handle, an M4 profile barrel with a cutout for a m203 grenade launcher, larger diameter handguards, and a six position collapsible stock with a canted buttplate.

The removable carry handle eases the installation of an optic. other than that the differences are mainly cosmetic.

Answer 2

Ok you are talking to an AR-15 man, So the main difference the handguards now personally i like the ones that look like an M16A2 Standard but hey it is your choice. Also look at the ammo it fires it could be a firing a 6.8 round and it could be something other than 1/9 twist.

Answer 3

The main difference is the length of the handguards

Answer 4

They are almost identical. However the hand guard is slightly different, and the collapsible stock on the M4 is a 6 position as opposed to a 4 position on the CAR. Also, the barrel with be stamped M4/CAR... I have a feeling that M4 is more preferable, hence the higher price.

Answer 5

One has a law enforcement type 6-position collapsible stock, and the other doesn't.

They also have different type barrels and possible handguards. Too hard to tell from the picture.
