Do what I and many others have done: order a Douglas 1:8 twist from Frank White at Compass Lake Engineering.
It was $280 plus $50 for the fitted bolt a few months ago. I had mine done in a 'medium' contour to save weight. It shoots just over 1/2 MOA with me yanking on the trigger. |

DN,
Ah not wanting to be rude why the midlength? The 18" SPR's are setup up for the long/rifle length handguard. Unless you can find the FFRAS Med/Long it is going to look a little odd. |

It's my understanding that the ARMS #58 SIR is intended for midlength-ported barrels and meant for SPR-type rifles. Is this not the case? |

I have a 20" Krieger that's shooting like that...[:D] |

DN,
The #58 is for the SPC Midlength... it is a 16" The #? Rifle length SIR is ARMS proposition for the SPR/Mk12 |

Thanks for the clarification, KB! I've heard the rifle-length, bi-level SIR was on the way soon. I have had such excellent success with ARMS products that I'd like to go that route.
In any case I think I'll look at CLE for a fluted Douglas barrel and matched bolt. Any suggestions as to who could do the final assembly? |

Wes Grant of MSTN has made some gorgeous and effective SPR's... (as well as any other sort of tactical niche AR/M16/M4 combo known to man)
Plus he seems to be able to get a lot of the kit before its retail debut as well. |

I put mine together myself, a tribute to the simplicity of the AR system:

The barrel is one thing ...the fitting, chambering and smithing is where the art is..
In other words a great barrel chambered by a merely adequate gunsmith will not be as good a shooter as a mediocre barrel gunsmith by a master... imo then there is also how long you have to wait.....and if you can... By the best you can afford and have it chambered by the best you can afford.. |

Agreed as well, that is why you have someone like Frank White turn and chamber the barrel, and select the best fitting bolt. The assembly process, in the words of someone here, can be done by any "ham-fisted spastic retard". |

"BEST 18" BARREL CHOICE FOR AN SPR?"
WHY NOT THE REAL THING? FRANK WHITE OF COMPASS LAKE BUILDS TO MIL-SPEC DIMENSIONS DOUGLAS PREMIUM STAINLESS SPR BARRELS IN THE ACTUAL SPR CONTOUR. THESE BARRELS HAVE FOUR FLAT END MILL CUTS FOR THE NEWEST PRI FLIP UP FRONT SIGHT, RECENTLY RELEASED BY PRECISION REFLEX, AS WELL AS A SINGLE BALL END MILL CUT AT THE 6 O'CLOCK POSITION FOR ALIGNING A STANDARD GAS BLOCK. [IMG]http://photos.ar15.com/ImageGallery/IG_LoadImage.asp?iImageUnq=10861[/IMG] THESE BARRELS ALSO HAVE THE PROPER "STEP" FOR THE OPS INC SUPPRESSOR BARREL COLLAR. LASTLY, FRANK HAND-FITS A BOLT TO EACH FOR MINIMUM HEADSPACE. AFTER FRANK SANDBLASTS THE BARREL, WE HAVE THEM K-G COATED FLAT BLACK. WE HAVE THEM READY FOR DELIVERY, WITH FITTED BOLT, OF COURSE, FOR $450. THESE BARRELS WILL SHOOT, TOO..... WELL UNDER MOA WITH FEDERAL PREMIUM MATCH AMMO! WES GRANT [URL]MSTN.BIZ[/URL] |

Wes, <[i]sniff[/i]>, that's just beautiful, man...
Looks like I know where I'm going to have the upper made up. I'll be talking to you soon! BTW, can I get that barrel fluted? |

WE WANT THEM BUILT TO THE SAME DIMENSIONS AS THE ONES CRANE GETS. ALSO, FLUTING ADDS $100 TO THE COST.
THE SPR BARREL IS A MEDIUM CONTOUR, NOT TOO HEAVY, ANYWAY. IT REALLY DOES NOT NEED FLUTING LIKE A SERVICE RIFLE, 1.00" BEHIND THE GAS BLOCK, MIGHT. WES GRANT [URL]MSTN.BIZ[/URL] |

Wes, Kevin, are we loosing much with the 18" as opposed to the 20"? I am going to ASSUME not much after knowing the velocity difference of 20" vs. 16" vs. 14.5". Have zilch knowledge of 18" but want to learn. Using the 75 and 77 grain, will we be giving up much distance in terminal velocity/wounding ballistics? Thanks.....Chad

WITHOUT EXTENSIVE CHRONOGRAPHING, IT IS HARD TO SAY WITH AUTHORITY. HIGH VELOCITY ROUNDS ON AVERAGE LOSE 50-75 FT/SEC PER INCH OF BARREL, ACCORDING TO MY FEDERAL AMMO BROCHURE. CHECK WITH THE AMMO GURUS ON THEIR FORUM.
THE U.S.M.C. HAS STAYED WITH THE 20" SERVICE RIFLE MATCH CONTOUR KRIEGER BARREL FOR THEIR PRECISION UPPER. THE MARINE CORPS PRESUMABLY VALUES THE KNOWN ACCURACY AND LONG RANGE PERFORMANCE OF THEIR 20" BARRELS, THE SAME AS THEY USE IN COMPETITION, OVER THE FLEXIBILITY AND PORTABILITY THE MEDIUM CONTOUR 18" SPR BARREL DEVELOPED BY CRANE OFFERS. I HAVE BOTH BARRELS ON DIFFERENT UPPERS. I PERSONALLY PREFER THE 18" SPR CONTOUR FOR GENERAL USE. I AM EVEN DITCHING A PERFECTLY WONDERFUL SUB-MOA 16" FLUTED KRIEGER TO BUILD YET ANOTHER PERSONAL SPR UPPER WITH AN 18" SPR CONTOUR. IN "FLAT EARTH" AND "FLAT OLIVE" K-G COAT. HOPE I DON'T LAY IT DOWN AND LOSE IT. THE SPR CONTOUR WILL OUTSHOOT ME UNDER FIELD CONDITIONS. I'M NOT PROUD OF THAT. IT IS MERELY A FACT. WHY HUMP MORE GUN THAN YOU NEED?
