just watched the art of the tactical carbine volumes, and my credit card is already hiding in a corner shaking (it knows ill be abusing it like mad now!)

already have most of the pieces picked out, but im wondering what lengths of barrels they were using in the vids are, and what length of larue FF handguard should go with it?

lookin for something similar to costa's setup, but cant find ANY info about his or travis' guns on the net.

any help?
 
Well, it's in the US, so some folk will rather not fork over the 200$ to have a barrel shorter than 16 inches, so I figure the longest barrel you would find at the carbine courses would be 16 inches.
 
AOTC is a good vid but you might want to do some research about what you want the gun to do and go from there rather then join the "I want to give Chris a hot oil rub down" club.

There are a ton of offerings out there for barrel lengths and just cause 16" is very common in the US doesn't mean you need that length here as our laws are quite different.

What ranges do you want to shoot at and what kind of shooting do you want to do, after the AOTC honeymoon wears off that is :D.
 
well ive had a 14.5 and own a 16" right now. wouldnt be looking to shoot it much past 100yds. just worried about ballistics, since ive heard that the shorter lengths (round 10") tend to be quite slower.
 
not sure what your getting at, 14.5" good to 300 yrds no problem 1-9" twist 62-69gr bullet is a stopper. as much as a 5.56 can be a stopper. it was never intended to be a stopper ever. it was designed to wound horribly and get that wounded person ie a russian to scream to his buddies for help. demoralizing and hopfully his friends do help him and then you have less people returning fire. 5.56 was never designed to be used against an enemy that does not fear death, or have no remorse for a fellow soldier who is wounded. sort of off topic but you can go down to 11.5" barrel and still be good to 100yrds. just keep it clean and lubed to get some reliablity. when you go short barrels you get more gas and then the problems start, like bolt bounce short cycling of action more blast heavier felt recoil and deminished accuracy. hope this helps and remember take opinions for what they are, just one persons opinion.

Coldfire, what airSOFt forum did you glean this tripe from?
:rolleyes:

As for the OP, the best length barrel would be whatever you're comfortable with. Try different drills with different setups. See what works for you. I can't imagine many nutz would turn you down if you asked to hit the range with them and try their setup(s).
If it is your only AR, and will do a bit of everything, then I'd go 14.5".
If you'll be building a dedicated upper, I'd go with one in the 10.3" to 11.5" range. Since you have a 16" already, I'd go this route.
In case you intend to join the cult of Costa, then you'll need a 16" barrel and lots of rail, because he holds really far forward.

Lost IQ points reading that drivel......Mods ban this fool before someone takes him seriously
 
To the OP, I say stay with a 16" barrel. It has great ballistics and is still very manageable in tight spaces. Just my opinion.

If you must go short, look into a 12.5 Noveske. Pretty nice length for a shorty.

As far as LaRue rails go, I'd personally go with 10" rails on either set up. Take a look at the Daniel Defense rails as well. The MK18 RIS II is a 9.5" rail and uses DD's excellent bolt up attachment method...can also FF an M203 :cool:

Anyway, in the end it's all about what you like and what you think you need.
 
Dont worry guys, hes a mall ninja.

coldfire at the risk of parroting my betters....please stay in your own lane.

Plenty with real life experience (not me) will confirm that a high velocity 5.56 is a proven killer of thousands of people of the last few decades.

as well to address the rest of your "special post" accuracy isnt a function of barrel length, but rather velocity is. A shorter barrel will loose velocity. Loss of velocity past a certain range can reduce the occurence of fragmentation of the round, which can reduce its lethality. However shorties can compensate for this at shorter distances by using heavier bullets, up to a certain practical limit. As for heavier felt recoil? I dont think this is an issue. Increased muzzle blast and noise is. My Christmas gift to the guys at the range is my new PWS brake ive put on my 10.5 LMT. Merry Christmas to all the deaf people ;)

The only ordnance I can think of off hand that was designed to wound and incapacitate a soldier would be a mini toe popper mine...not the 5.56
 
Chris Costa and Travis Haley have Knight's SR-15E3's (16" barrel) for most shooting, but I build them our now standard SR16E3 CQB uppers.

Which is an 11.5" barrel
in comparision to the old SR16E3 CQB - we adopted using longer rails since the majority of the customers of these guns appreciate the longer real-estate, keep in mind our FFRAS-MRE was the first of the longer rails desgined for a unit that appreciate FF and longer rails, but wanted to keep the front sight gas block, so we are really just catching back up with ourselves, with the advantages of a folding front sight that is integral to the rail

and its 14.5" brother with M203

Both GL's are freefloat - and unlike the M203 the HK can use a can on a 11.5

Chrisward, my experience is with HK's but same round. We used G36C's with 8.5" barrels. Even with the the thick plastic front sight 200 yard hits on a human silouette were easy. Put a trijicon reflex on it and it was dreamy.
They were not much longer than our old MP5's so they were great at CQB.
Muzzle blast is fierce on a barrel that short. Its like a mag full of mini flashbangs.
