kimberacp Posted December 29, 2013 Share Posted December 29, 2013 Has anyone used a 16" with a rifle gas system??? Is a rifle 18" barrel w/ rifle gas preferred over a 16" w/rifle gas system?? thanks Link to comment Share on other sites More sharing options...
Steve RA Posted December 29, 2013 Share Posted December 29, 2013 Only thing I can see that would be wrong with it is the short distance between the gas port and muzzle. Could lead to a lack of gas pressure or volume. Link to comment Share on other sites More sharing options...
mpeltier Posted December 29, 2013 Share Posted December 29, 2013 DPMS makes/made a rifle gas 16". I played with one for a while. It worked with good ammo but ultimately I concluded it did nothing better than an 18"-20" bbl. and it did some things not as well. Link to comment Share on other sites More sharing options...
ViktorCistic Posted December 29, 2013 Share Posted December 29, 2013 I am owner of dpms Tac2. 16" barrel with rifle Gas system. Actualy 1000rnds without single problem. Link to comment Share on other sites More sharing options...
dmshozer1 Posted December 30, 2013 Share Posted December 30, 2013 I am owner of dpms Tac2. 16" barrel with rifle Gas system. Actualy 1000rnds without single problem. I ran a DPMS 16" 1-9 twist rifle gas barrel in 3gun for three years. Shot it out. Bought another one. Ran it until it shot out. Used different comps, all kinds of ammo. Using good ammo, because it was short and stiff, it held 1moa out to 300. I think if it had a 1-8 twist it might have been better. Don't know. Accurate enough for 3gun in my opinion. Recommended one to a friend. Same deal. I switched to a 18" and really don't know why. I think it was because DPMS said it would be awhile before they would have another production run of them so I got a DPMS Mk 12 that was in stock. I believe Bruce Piatt ran a 16" He seemed to do okay with his. Link to comment Share on other sites More sharing options...
TRUBL Posted December 30, 2013 Share Posted December 30, 2013 (edited) From a reliability standpoint.....18" with a rifle gas system will pretty much run any bullet weight out there and still function at velocities that you'd run for 3 gun. 16" will as well......but as you get into the lighter/faster bullets.....you MAY see that reliability go away. If you use heavy bullets, (68 and heavier) at around 2700 FPS, you MAY never see an issue. 55 grain bullets above 3000 fps....MAY cause you some reliability issues.......at 2900 FPS, chance are...it'll be good to go. 35 grain bullets at over 3300 fps....probably won't work out of a 16" with a rifle gas system......the bullet will most likely leave the end of the barrel before the bolt opens.....BUT....then again....it MAY work. Basically.....the closer the gas hole is to the muzzle.....faster/lighter bullets become a question mark as to reliability.

Nick S Posted December 31, 2013 Share Posted December 31, 2013 Noveske has made 16" barrels for MSTN with an intermediate gas system. Slightly shorter than rifle gas system but longer than mid length. A friend has one and if works fine with 55 gr 193. Link to comment Share on other sites More sharing options...
Mr Player Posted December 31, 2013 Share Posted December 31, 2013 I have both a noveske 16" intermediate as well as a 17" rifle barrel. They are both great. I am going to use the 17" next season for a game gun. Coincidentally I just talked to Wes the other day at MSTN and he just got a batch of the 16" intermediate barrels in. Give him a call if you want one. I'd like to add that the 16" may be the most accurate barrel that I have ever owned. Pic of that gun Link to comment Share on other sites More sharing options...
midengine3sgte Posted January 1, 2014 Share Posted January 1, 2014 one of my build that I'm toying with is a 16 inch with a rifle length gas system. I haven't finshed it yet but wanted to know what size gas port is on your barrels so i can have a good starting point is it is not cycling right. not sure if I should just get an adjustable gas block.

kimberacp Posted January 1, 2014 Author Share Posted January 1, 2014 what gas tube would you use for intermediate length? does anyone make one??? Link to comment Share on other sites More sharing options...
Nick S Posted January 1, 2014 Share Posted January 1, 2014 Noveske supplies it with barrel I think. KACs also may have one. Link to comment Share on other sites More sharing options...

An adjustable gas block is not going to help if the hole in the barrel is to small to cycle your gun. The block is meant to turn down the gas when the hole is bigger than necessary. The adj. block can then close off the hole reducing the amount of gas to operate the gun. I had two DPMS 16" rifle length barrels. Both had .100 size gas holes. They were both over gassed. Fixed them with adj. gas blocks by turning the gas down. Good luck with your build. You will learn a lot by the time you are done with it. Link to comment Share on other sites More sharing options...

TonyH Posted January 4, 2014 Share Posted January 4, 2014 I ran a 16" rifle length gas for several years when I was with DPMS & never had any problems shooting 55 gr. Blitz Kings at 3150. It would shoot under 2" at 300 yds. Still have 2 of them & both are great shooters. Only problem I ever ran into, is when I put a titanium carrier in it. Then it started to not cycle properly, changed back to a standard carrier & problem solved. Shooting a JP 18" now with rifle length gas. It always works no matter what carrier is in it. Currently running a Rubber City Armory low mass carrier. Link to comment Share on other sites More sharing options...
