Well, I've got nearly all the items layed out for my SPR project except for the most important part. The BARREL. What are good stainless or chromed 18", midlength tapped barrels out there? Eventually it will wear an ARMS #58 SIR and PRI gas block / folding front sight post.

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?

That sounds like quite the barrel! 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: [img]http://photos.ar15.com/ImageGallery/IG_LoadImage.asp?iImageUnq=9365[/img] Wes at MSTN does carry all the cool stuff, and has built some sweet uppers...

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".

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?

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
