survivalshop Posted June 17, 2010 Report Share Posted June 17, 2010 Strange they didn't go below 18 " bbl..I will get a chance this week to see how my 308 ,16" does compared to my 20 ". Just waiting for my bolt stop screw(s).I have always been one to believe a stiff short bbl. is better than a thin long bbl.. I have built a few 16" carbines & have never used any thing but a med. wt. bbl. . Since I will never put a launcher on one of these rifles ,the M4 bbl. is useless to me. I guess if you want the look of the M4 rifle ,that's fine ,just not for me . Quote Link to comment Share on other sites More sharing options...

jmatt511 Posted January 29, 2011 Report Share Posted January 29, 2011 I'm an old bolt guy by training and profession. My opinions are based on those parameters. I'm just now delving into the 7.62 AR pattern rifle. Just got home from playing so I haven't had time to read the articles. Hopefully I'm not covering material already discussed. It all depends on what kind of shooting you intend to do and what your requirements are. If you are looking for accurancy and down range performance, your barrel length needs to be compatable with the type of round utilized. If you're throwing 147 to 150 gr down range at paper, then a 16" barrel will provide reasonable accuracy. However, if you're ranging out past 400 yards and want sub MOA accuracy a 20" barrel is the very minimum. My bolt gun uses a 24" bul barrel. My 7.62 AR is a 20" SI Defense SASS heavy profile barrel. Shooting match ammo (GM 175gr BTHP) anything over a 26" barrel will not enhance terminal performance. Please remember, I'm only talking about .308-7.62x51 NATO. Other calibers differ greatly. A light weight or pencil profile barrel will do nothing for your accurancy. It all depends on what you intend to use your rifle for. My bolt and AR are pigs at over 15 pounds each. Not good for room to room. But give me open sky and I can hold my own. Thanks for listening and shoot straight guys. Quote Link to comment Share on other sites More sharing options...
Madhouse Posted January 29, 2011 Report Share Posted January 29, 2011 Interesting reads. I've recently been at opposite ends of this topic with my chief instructor since I told him about my new 16.5" .308 AR. He had a blanket claim originally that a carbine-length .308 was too short, but was surprised by the claimed velocities.Thanks for the links guys!

survivalshop Posted January 30, 2011 Report Share Posted January 30, 2011 I just did a comparison with my 16" & my 20" with regards to velocity with my new Chronograph. There is not much diff. at muzzle (10')16" BBL. avg. FPS w/XM80C/149 gr. bullet- 2676 fps20" BBL. avg. FPS w/XM80C/149 gr. bullet - 2781 fps Diff. --105 fps16" BBL. avg. FPS w/ 172 gr. bullet, handloads 2362 fps20" BBL. avg. FPS w/172 gr. bullet ,handloads 2484 fps. Diff. --122 fpsNow I know I can boost my handloads up a bit & I have different bullets to try also & new LC brass (well once fired )I know once I boost the charge of my hand loads ,the vol. spread difference will decrease.

Robocop1051 Posted January 31, 2011 Report Share Posted January 31, 2011 That's awesome info! It furthers the discussion that every inch beyond the 16th inch will add approximately 25-30 feet per second. The math is right there in the proof. That still puts a .308 supersonic out to 300+ yards with a 16" barrel. I'm ok with that result. I've never had to kill anything beyond that range, besides paper... and even that is an extremely rare occasion. I'm completely sold on the 16 incher.

sellmarkguy Posted May 3, 2011 Report Share Posted May 3, 2011 That still puts a .308 supersonic out to 300+ yards with a 16" barrel.I have heard field reports of some 16" .308 barrels delivering supersonic to 1,000 yards! Quote Link to comment Share on other sites More sharing options...
bgc Posted May 3, 2011 Report Share Posted May 3, 2011 I like my long heavy barrels. Don't have a damn bit of science or logic to back this up with. I think the short, stubby guns look funny. Quote Link to comment Share on other sites More sharing options...
sellmarkguy Posted May 9, 2011 Report Share Posted May 9, 2011 I like my long heavy barrels. Don't have a damn bit of science or logic to back this up with. I think the short, stubby guns look funny.For my needs, it is a matter of modularity. I look for ease of being able to carry my rifle, loaded with ammo, spares, etc.Longer barrels add weight, and I prefer longer barrels for bolt-guns. Although, my AR15 is a 20".

YWHIC Posted May 11, 2011 Report Share Posted May 11, 2011 I know my 16" DPMS with HEAVY BARREL holds good thus far at 200 yards.. shot 1 5/8" this past weekend with 10 rounds @ 200yds. :)Shot some Hornady 150gr SST & Hornady TAP 110gr.. both rated at 3000 FPS on the boxes..

hobbesgunner Posted May 11, 2011 Report Share Posted May 11, 2011 I'm with bcg on this one.....just got that longer, heavier shoots farther, better stuck in my head.....don’t mind carrying extra pound or three...read article some years ago on barrel length affect on handguns. Started at 12" and cut 1" off between tests with no real difference in accuracy till 2"...velocity drop was considerable though....I just work with what I'm used to I guess. ;D Quote Link to comment Share on other sites More sharing options...
bgc Posted May 11, 2011 Report Share Posted May 11, 2011 Dont know if the barrels longer than 20" help accuracy, but at 26" an 16 pounds I can club somthin with my 22-250 when I run outta ammo.... Quote Link to comment Share on other sites More sharing options...

Ranger_Edge Posted December 5, 2011 Report Share Posted December 5, 2011 I love my 16" AP4....! Quote Link to comment Share on other sites More sharing options...
rhinegarten Posted February 7, 2012 Report Share Posted February 7, 2012 Me too! :) Now that it's built and close to being broken in I'm lookin to do a little tweaking in the recoil reduction department, not that it's all that bad now. It's easier on me than my HK91, which is heavier. And after 20 rounds or so, I end up literally with a bruised black and blue shoulder. Firing over 40 rounds in an afternoon with the AP4-not even sore. Quote Link to comment Share on other sites More sharing options...
edgecrusher Posted February 7, 2012 Report Share Posted February 7, 2012 try the carrier weight system and a heavy buffer <thumbsup> Quote Link to comment Share on other sites More sharing options...
rhinegarten Posted February 7, 2012 Report Share Posted February 7, 2012 Already been eyeing the heavy buffer by Clint. Not familiar with the carrier weight system. I'll have to poke around on that one. Quote Link to comment Share on other sites More sharing options...
RayGun19 Posted February 7, 2012 Report Share Posted February 7, 2012 How does the OBR stand up to all this? They offer 16, 18, and 20" barrels. Anybody know? Quote Link to comment Share on other sites More sharing options...
cz777 Posted April 24, 2012 Report Share Posted April 24, 2012 Dont know if the barrels longer than 20" help accuracy, but at 26" an 16 pounds I can club somthin with my 22-250 when I run outta ammo.... accuracy is not in part of this ,with iron sights at extended sight radius for accuracy .now with scopes but FPS is the key to range and bucking the wind is .....so a stiffer barrel will do the job better etc look at lowlight's shotting at sniperhind with a 16'' barreled ar-10 config ....
