Bushmaster makes one. IIRC Model 1 does, too (I'm not recommening it). I built one from a Bushmaster barrel and Les Baer upper w/o forwars assiste (to minimize weight) with a Clark Custom (same as DPMS) carbon fiber free-float tube and a colt bolt/carrier group.

On the EE you can find Colt 6520 uppers (A2, 16" lightweight) for $400 without the B/C/CH. I doubt the CMMG upper will be much cheaper than that......

If they're the same price, I'd go Colt's all the way. Not saying that CMMG makes a bad product, but I'd prefer the Colt's upper. The Colt's barrel has the "proper" FSB; CMMG does not. If you don't care about the contour of the barrel under the FSB, then of course it's a moot point, and I'd go CMMG in that case because you'll likely save a little.

cmmg is a .750 bbl. turned down to lightweight profile but still .750 at the fsb.
bushmaster and colt have the true .625 fsb |

Exactly... Therefore, a Bushmaster or Colt lightweight will be lighter than a CMMG, Model1, DPMS, etc. Of course, the Bushmaster doesn't have M4 feed ramps, but I have one and have never seen the need for the M4 ramps. Building lightweights is fun... If you don't already have Forest's weight table, get it! It makes planning a whole lot easier. |

The Colt 6520 has a regular front sight base. The F front sight base is just for flat tops. I love the 6520, I just wish I could get it with A1 sights. |

Is that good or bad? Seems like a good deal to me.

at least 100$ less than anywhere else for similar setup. plus it is 1/9, chrome lined and colt profiled, e.g. lightweight throughout barrel. since I was already prepared to spend 550-600 this means I can get a DD7.0 installed. it actually weighs about .3 ounces ess than teh handguards and barrel nut and HG retaining cap. so it's a weight saving measure. at least that's my excuse. |

That's what I thought you meant. A similar Model 1 chrome lined is $420. I would prefer the Eagle setup as I have had good deals with them before.

That's awesome! If I didn't already have one, I'd have to buy one!  Hey, not to go spoiling anyone's need to buy goodies, BUT the DD 7.0 is lighter than M4 handguards, but NOT standard carbine handguards. (Again, you need to get Forest's excellent spreadsheet) Also, that DD 7.0 weight is for the bare forend, WITHOUT rail covers. Ladder panels weigh .5 oz each, so 4 full ladder panels increase the weight by 2 ounces. The MagPul XT panels weigh .6 or .7 each, I can't remember. |

+1 Forest's spreadsheet is a great resource. If something's not on there, slap it on a scale and email him. He'll update the spreadsheet and add you to the credits. The one-piece handguard/free float tube DPMS and Clark Custom guns sells are hella lightweight. The DPMS ones weren't available when I did my build, so I cut down a Clark to carbine length. 4 oz. even, IIRC. If you can live without a forward assist, Les Baer and others sell regular flattop uppers without them that save an ounce or two. Some of the flattops without FAs are actually heavier than a regular flattop with an FA because the walls are thicker. IIRC that is the case with the DPMS Lo Pro. |

I want to say 7 oz. It might be on Forest's spreadsheet - I weighed mine before and after I cut it. I just don't recall the pre-cut weight for sure. I used a Clark, but the Clark and DPMS units look identical except the DPMS units have anodized barrel nuts. BTW Rainier Tactical/Northwest Tactical (a spondsor in the Industry section) has the DPMS tubes on sale right now. |
