Several months ago I got a DPMS upper with a BHW 308 barrel to try out. Nothing fancy. Bare bones one might say..LOL  Obviously while I hat the heart without the other parts it wasn't going to go very far. I was on a quest so when time permitted I started nosing around. As the platform is non-mil-spec I had to look carefully for a lower for this one. Of course when I got this lowers were all over the place and when I started looking the supply line was empty. I was down talking with Dan Young and mentioned I needed a hand guard. He rummaged around and found one of his tubes that he had made a run of several years ago. There was also a Quentin Defense lower available at the time so I was in the hunt moved along in my parts gathering some more.   I had to step back for a month or so but got out the plastic and ordered up some stock parts and and a few lower parts. I had already talked with George who owns BTE and had a low pro adjustable gas block. He alluded to having a trigger, some anti-walk pins and one of his super charge handles that I like so much. I didn't have the gear to assemble all of this so when I took the box job over to George we discussed a Cerrakote job for it. I'll probably only own one of these so for once I steeped away from my Men In Black mentality and decided in honor of my Grandson's interests I'd go with a Zombie Green/Black mix but of course we adults would say it's a Ghillie motif as we are adults here. Leaving the chore of assembly and finish up to the Master I left for the day. Coming back after getting the high sign from George we were ready to rock. I had dropped off two magazines also so they were part of the package. I was shocked at what was on the table and started grinning from ear to era. I got it home and mounted up a scope this weekend after chasing down some rings. The 4X12 Leupold should let me wring it out post haste.   So there you have it. The muzzle device wil be picked out later. I can say that the BTE parts added some real quality to this build. I didn't have the barrel painted as I will be trying some other chamberings on this one and when the finalist is picked I'll get that one done. My thanks to Black Hole , BTE and Young for their assistance in this build. My wallet is a tad lighter but I have some pep in my step and glide in my stride. Hopefully a range trip this week. Greg |

That Zombie job is 'sick' as the grandies might say. How did it wring out? Is that handgard a 12 over a rifle length gas sytem?
Regards,
CP

Any group pictures?? I'm looking to get an AR-10 build going, trying to narrow down barrels. How long is your barrel? Rifle gas?

Handloads later next month. I'm getting ready for the Senior Olympics so have been jammed. 24" rifle length gas. Greg |

Regards, CP It shoots well. 12" guardstops just at the back of the block. Greg It is interesting that the 12 inch hand guard stops right at the back of the gas block. That is, of course, how it should be. The 308 24 inch bull barrel I got from BHW about 8 years ago has a 1/4 inch gap between the end of the 12 inch hand guard and the back of the gas block. It looked odd to me because I had a DPMS 260 Remington upper with a 12 inch hand guard that stopped right at the back of the gas block. When I brought this to the attention of BHW I was told "that's the way we make them". I guess they don't make them that way anymore. |

They are the same location on the holes.. They have to be. The factor of the gas length is the same no matter what year. What you are seeing is two fold. Not all rifle length HG's are 12". some are longer some are shorter. This one is, measuring now......mine is an old YOUNG he had stashed that I talked him out of and it is 12.75". I have had some rifle length tubes that were as short as 11.75". By and large they tend to be about 0.250 over 12" from the bunch I just measured from various makers.
Not all GB's are the same from the gas port to the back of the block. You may see as much as 1/4" depending on who made it. Most will be very close but I've sen some that were extremely short in the back.

I just measured the barrel on my 308 with the BHW barrel and I measured the barrel on my DPMS factory assembled 260 upper. I measured from the front of the receiver to the step in the barrel where it is machined down to the gas block dimension. I didn't want to disassemble the rifles so I just used a tape measure and my eyeball. The distance from the front of the receiver to the barrel step on my 260 is 12 11/16" the distance on my BHW barrel is 12 15/16. Exactly 1/4 of an inch. Also. as you might guess the gas tube protrudes into the receiver 1/4 inch less on my BHW barrel. This is what concerned me and caused me to call BHW and I was told there is no standard on 308 AR barrels like there is on AR15 barrels and that is the way we make them. What is the distance from the front of your receiver to the barrel step on the rifle you have pictured in this thread? Oh, by the way, this is the same 308 barrel I may be having headspace issues with that I posted in another thread but i'm sure you already figured that out. |

They must have sent you one with the ARMALITE gas system drilled. MOST are 1/4" less as you have discovered. The AR10 style guns suck for compatibility IMHO.

I ordered a dpms pattern barrel. I knew the AR10 barrels were different. I just did not know in what ways they were different. Well, in anycase I got this barrel 8 or 10 years ago so I am stuck with it now. I waited a year to get it. The odd thing is that BHW assembled the upper for me. I brought what I thought were problems about the headspace and the position of the gas block to the attention of the company so the owner of the company, I can't remember his name at the moment, called me and offered to assemble it for me which I thought was great customer service. Now, knowing the difference in the barrels I am surprised they didn't catch it. I told them I was checking dimensions against a DPMS upper I had. I guess that didn't ring any bells with them. |

I'm glad some of that got clarified. Ten years ago it was a crap shootIMHO on what was going on. I've been on the Pro Staff since 2011 so I can say it wasn't me..LOL Perhaps an Armalite forearm could be obtained.
Let me know how it goes with future die adjustments on brass life..

Greg Thanks Greg. You have been a great help. I'm not concerned about the gap in the handguard. My main concern was that the gas tube was not projecting into the receiver far enough but I guess it is. It seems to shoot fine. I'll cycle a few cases several times bumping the shoulder back about .003" during reloading and I'll let you know how it goes. I'm going to have to get on that quick. It is already getting hot. |

Ever get any groups shoot with handloads? My .308 barrel will need replacement by the end of the year. It's been on the back burner but I'll get off my butt and shot a few in the next few months. Greg |
