I would steer clear.
The rail is not free floated, and it suffers from some pretty severe carrier tilt (where the bottom of the carrier chews up your receiver extension or "buffer tube").
Also, stay away from the Bushmaster rifles...their BCG's are seldom staked, castle nuts are almost never staked, barrel twist is always 1:9", the BCG and buffers are too light (ar carrier and carbine buffers rather than M16 carrier and H buffers), and the list goes on. Here is some photographic proof for you:

Some of the best built rifles are coming from BCM, Daniel Defense, Noveske, Colt, and LMT.
Building a carbine isn't all that complicated either, so long as you pay attention to the details. Most of the less expensive companies cut corners; so if you don't cut corners building, you can have a very reliable rifle.
Also, the delton kits tend to ship with .223 chambers, if I recall correctly. If you plan to shoot .mil ammo though it, or Federal XM193 or any other 5.56mm ammo...I would either make sure you had the chamber reamed, or select a different barrel/ kit.
