308 16" L/W rifle length gas build

[archad]

I have been wanting to shoot a 16" .308 with a rifle length gas system since seeing Buckjay's 16" LMT build. I had a CMMG 18" mid length complete that I got for $1100 in early 2012. I sold the 18" barrel and ordered a Fulton Armory 16" L/W with rifle length gas system. I went this afternoon shot it on paper at 25yds then to 100yds.


First 2 shots low turned the Leupold 1.5x5 up 1" and fired 8 more shots. Its shoots better than I expected for a lightweight barrel and it so soft to shoot compared to my other mid-length 308's.


ETA:Build info 12" Troy TRX with Noveske bipod stud ,Noveske quick detach socket, JP trigger, JP low mass BCG 5 oz lighter than a standard BCG,Vltor A5 RE with H3 buffer, Mapul STR and Magpul Moe +. 16" Light Weight Fulton Armory barrel has .625 gas block seat BCM gas block. ETA: scope is the Leupold 1.5x5 CMR-2 reticle.

Thats a slick looking piece. I also have a 308 AR in process that getting a Fulton Armory barrel (sourced from Criterion I believe). It is getting one of their 20" heavy contour barrels. Lower/upper is SI Defense, rail is a TRX-308 just like yours.

I think that the 16" rifle gas is a fantastic combo for a 308 AR. About as light and fast-handling as you can get for a 308 Win semi auto rifle...

I also imagine that it will shoot better with a couple more rounds down the pipe.

Nice rifle OP!

Nice looking rig OP. How many rounds have you fired through it and have you had any failures?

[archad]

twisted: I have fired only 14 rounds so far.

I'm very interested in this project.

Please update this with accuracy and reliability info as much as possible.

I feel your pain. I got my Sig 716 in early December. I have just recently shot it past the 150 mark.

Also very interested in reliability potential of rifle length gas in barrels <20".

Same deal with intermediate length gas on a 16 5.56. Or mid-length gas on a 13.5, or rifle-length on an 18.

As long as it's a *competently* factory produced barrel (not something somebody chopped off 4 inches off the end and called it good) with a properly engineered gas port, then it should be reliable.
Cheap milsurp 7.62 would be the test ammo ran with a dirty, gummed up bolt/carrier in all temp ranges.
