I've always thought about doing an SPR with an 18" barrel but it was way down the list. Then I find out that I won a LaRue barrel and I chose an 18" Stealth.
Now that I have the barrel on the way I have no idea where to go with it. I've been thinking about 16" guns for so long I feel lost. I have wanted a Mk12 but LaRue isn't a legit Mk12 barrel so I don't think I'll go for a Mk12 clone. Those of you with 18" SPR's, can you post pics to get some ideas flowing? Please post parts list with it if possible. Thanks! |

He won an 18" barrel. Those 16 inches won't help him and I've never got any of my 16" rifles to shoot as soft as my 18".
Personally, I think an 18" barrel with a kac urxiii are pore sex. |

Unless you're building a clone, 18" doesn't do much that a 16" wouldn't handle. It depends how far you are shooting... at 600 yards, it does make a difference. Not much with the better bullets you can get today that will meet those velocities out of a 16" barrel. The biggest advantage of the 18 has always been its rifle length gas system. Go look and see what 3 gunners use. In reality 2 inches won't slow you down, 18 inches is still short for anyone that's spent some time behind a bolt gun. |

He won a Larue barrel. He can pick any length he wants. I won a Larue barrel as well and chose the 20in Stealth because I wanted rifle gas. Larue does not use rifle gas on their 18in barrels.

Unless you're building a clone, 18" doesn't do much that a 16" wouldn't handle. It depends how far you are shooting... at 600 yards, it does make a difference. Having just send a few hundred rounds of IMI Razor Core and CBC 77gr ammo out of both my 16" and 18" rifles on Thursday, with crosswinds, at 250y, 500y, 600y, 600m, and 750y steel... No. And not based on the range trip before that, or even the numerous ones last year. No more than a few 1/10s MIL in terms of dope, basically the same wind call. If you chart it out, the velocity difference isn't that significant. Yes, one may poke the plate a wee bit harder, but we're not talking about 5.56 vs .308 here. This is same round, same bullet, maybe 50 FPS difference in velocity. Both are still supersonic at 750, which is already far enough for a 5.56. Both are subsonic before 1000. Why choose the 18" barrel? A good 16" barrel with a 77gr or similar bullet as fast as possible makes for a great 0-600 gun, that can stretch out to ~800 as required. If you're really trying to get past that, why are you using a 5.56? |

Didn't mean for this to become a 18" vs 16". The decision has been made an I have an 18" barrel on the way. I'm just looking for some pics for inspiration.
Thanks to those that have contributed. I really love the PRI handguard look but still want to avoid going towards a Mk12 clone. |

yeah, not mine though View Quote No, it's hot, and I bet it's light with the Aero mount, 'tar barrel, and that freefloat handguard. I've been on a lightweight kick and lightweight is sexy. I went with the stealth barrel to mix it up and get some weight in my life. I'm thinking maybe...a UBR stock? For some reason I don't want to go with the basic forged receiver and maybe try something special. I'm not thinking Battle Arms or 2A lightweights, but something different for me...maybe SMOS? |

I won a barrel on 8/18 and can't decide which 18' i want.
I've got a lower build kit with an ACS-L stock already, and a aero lower Will likely grab a Aero enhanced upper with either quantum or enhanced 15' mlok rail Cant decide if I"m better served with an 18 Tar or 18' stealth and the extra 13 oz |

I went Stealth because I wanted to have something heavy in my closet that I can sit on a bench or prone with. Just wanted to change it up a bit. Part of me also wishes I went 12" as a motivation to finally SBR a lower but oh well. |

here is mine:
LaRue Stealth 18"
Midwest Industries MLOK 15" rail Armalite lower of some sort... "extra" I had LaRue MBT Trigger (love it) Nikon M-223 3-12X scope (BDC reticle...meh). Harris Bipod YHM muzzle brake for suppressor. I've taken out to 300Y and done OK with it, using primarily Mk262 or similar (IMI razorcore, CBC). I don't like the BDC reticle that much though. Out to 200 it is like a laser but at 300 the "OK" is due to the shooter not the weapon. |

Ha, I won a free barrel from Larue, too! To date it has cost me over $700!
I chose the 18" Predatar barrel with a lightweight spr build in mind. PSA lower with ACS-L stock, 15" BCM KMR alpha rail. Hoping to put a vortex 2-10x on it someday. |

The data is out there for all to see. Hint, it's insignificant between a 16" and 18" barrel. IIRC it's around 50 fps. You can keep you 2 inches. |
