Thinking of doing this just wondering how many people do this and thoughts on it. advantages/disadvantages. Pics if ya got um would be cool too. Thinking of using they YHM light weight rifle length railed forend.

Less hot barrel comes in contact with my legs or hands (or burn my car's bumper lol), more rail surface that allows me to mount my light all the way up, room for PVS14 (I put an Aimpoint M2 way ahead on the handguard), sling attachment adapter can be put all the way forward too.

DD 12.0, 16" Midlength,... Balances VERY well with the Cav arms A1 stock, Jumps around a lot less than a carbine...

This was the first one that popped into my head.  Nobody has yet mentioned the increased sight radius and accuracy potential.

And they look damn businesslike, no extra barrel hanging out there to snag shtuff with.

"Nobody has yet mentioned the increased sight radius and accuracy potential"

When I get good enough with irons to see a difference between the two sight config's Ill start mentioning that

Well Mongo, it's because I intend to use a scope with mine, the backup sights are well, backup sights

Here's one of mine...

Here's my first AR ...  Frankenbuild that it is.

I'll post a pic when I get mine back...new KAC MRE on a 14.5" M4 bbl..

Here's one with the DD 12.0 rail.

Lots purdy guns

Yah I think this definatly sealed the deal. Doing the rifle length tube on a 16in barrel. yup Thanks all.

I have no pic to show you, but I have a DD 12" tube over a 16" BM M4 barrel with the PRI gas block.  I did this specifically to have the long sight radius on a carbine for accuracy at extended ranges.  It worked out exactly as hoped, my 200yd group size (w/ irons) with this 16" bbl is the same as with my 20" bbl, something I am utterly incapable of doing with the standard carbine sight radius.  I must give "props" to Capn_Crunch, his rifle was an inspiration for this project.

Sights: LMT rear, Troy front.  I chose the LMT because the sights on this rifle aren't "back-up", they're "primary", and I wanted the A2 sight system to be a part of it.  Then again, I'm pretty sure no magnified optics are ever going on this rifle, or I would have had to choose a folder.

Photoman, I know you said you're considering the YMH lightweight rail...  I have one on a scoped 20" platform, and it's a good system, but may I suggest you look into a DD for your carbine.  I know it's way more expensive, but there's definite advantages.  First, WEIGHT.  Second, better locking system to keep the rail in place and completely prevents any accidental handguard rotation.  Third, tube shape - the DD isn't round, it's oval like an M4 handguard and is way more suited for gripping than the round tubes.  As soon as I felt that M4 profile on the DD I was a believer.

First time trying to post a pic.  A Larue 12 in. on a CMT Upper, and modified 16 inch Dissy BBL.http://img.villagephotos.com/p/2004-9/822895/Dissy1.jpg

I put together a few of the uppers shown there on the top... Gas system is mid length and the FSB is removable so you can get the handguard off for cleaning, I think this is my favorite setup of all.

Thanks!  Most people who see the upper think the PRi SPR rail is a factory piece since the machine work and refinish is so clean.  I'm gonna snap a couple better pics of the finished rifle one of these days to put in your Industry Forums brag/pic thread.  Could not be a happier customer!

double_r76,

I'll say it again..I really like the PRI rail setup you've got on that rifle.  The rail is just long enough to forward-mount a scope on conventional low/med rings, but doesn't add miles of useless rail and weight to the gun.

We need to see some better pictures!

Wes,

Is that the new Nightforce?

There are some really nice guns in this thread: double_r76, Capn_Crunch, SMGLee, and of course Wes.

Is anyone here not using the mid-length gas system?

Carbine length gas system here... my upper is a Colt 6721 with 16" HBAR turned down and then fluted, has M4 feedramps.  Taking more pictures is on my "to-do" list!

Mine's not at current, but I'm working on it...
