  1. I can tell you first hand the more research you do the more frustrated you will be.  At least that was/is the case with me... I have built quite a few AR's in .223 so when I decided to build a BO I did it the same way. I used a 10.5" Black Hole barrel with pistol gas.  Pistol gas is the only way to go IMO. I used all the same stuff I would have used in a .223 build, JP low mass BCG, JP SC spring, SLR adjustable Ti gas block etc... I shot maybe 20-30 rounds, all un-suppressed and it ran fine.  I think the issues may come when I FINALLY get my can.  I have a full mass bolt and I have a JP H2 SC spring ready and waiting.

  2. I have a 1-7 that doesn't shoot 55's very well that is why I would prefer a 1-8. I also would like the better velocity of an 11.5" I have read a few places that the difference is pretty significant. I use adjustable gas so I don't need a reduced size gas port. Thank you for the suggestion on V seven

  3. Looking for barrel suggestions.  I am looking for 1-9 or maybe 1-8 twist, I don't want 1-7 Doesn't need to be a light weight or military profile. I love black hole but they only offer 10.5" or 12.5" this will be for a suppressed rifle. Any suggestions?

    Well I finally figured out why my Stretch-16 barrel wasn't shooting so great.

    First I thermal mated the barrel and shimmed it to the upper. Wow, that even made PMC 55gr look almost like match ammo.

    It took groups of about 2.5 MOA down to about 1.5 MOA. From what I have seen out of other rifles 2.5 MOA is standard for factory 55g ammo.

    The second part I stumbled onto.

    Apparently my barrel's head space is a little tighter than I expected and very well might be the reason with FGMM 77SMK shot like crap.

    Using my head space comparator, I noted that the fired head space of a PMC round was the exact same head space of the un-fired FGMM 77s.

    The difference between a fired 55g and 77 gr un-fired head space is .003.

    Now that I have started moving the shoulder back an additional .003 on my re-loads, which matches most factory loads, it shoots much much better.

    Has anyone else noticed this on their Stretch-16?

    Is this normal or did I get a one-off barrel?

    I am trying to get some accurate 55 grain loads.  The one I have shoot amazing with 69 grain but sucks with 55's  Like 3-4 moa sucks I am shooting H335 with 55grn hdy bullets and magnum primers.  I really want to only shoot 55's...

    It is the Trijicon RMR RM07 6.5 Moa dot. I have not shot it very much at all. I have had it for a year and maybe 250 rounds. i really need to spend some time on load development and break in. I hate that I am not shooting it. I have the exact same setup in iron sights with no ports also.

    I'm kinda waiting the the 1-8 BRT-I to come out and they seem to be about $2,419.  The 1-6 seem to be $200 less new.  How much are you asking for yours?

    The 1-6 new are like you said 2250.00 without the throw lever. I had not seen prices on the 1-8 until today when I looked and it looks like it will be around 2850.00.  Mine is 1.5 years old and is in really nice shape. With a Larue mount $1950.00 without $1800.00. I have the box, papers and the $100.00 throw lever.

    educate me... i can see needing to adjust for weather or altitude if you are a well traveled three gunner. But why the need to adjust all the time? I set mine to my competition load, locked it in and forgot about it. I recently changed my barrel out and had to do the process again but didn't have anything locked up. Sprayed Kroil on it and worked fine. 

    I put together a couple rifles every year for competition. I do travel to matches (only 5-6 this year 'cause I am old and poor) I have gotten in the habit of "exercising" the adjustment just to try and keep it moving.  I am a tinkerer and I always seem to "have" buy the latest coolest thing so often I have to go through the adjustment process a few times during the season. I know a lot of 3 gunners and many have the issue with freezing gas blocks. Is it a big deal? most of the time no. I do have a couple of suppressed rifles that I shoot sometimes without the can and they are way over gassed with the can -vs- without so being able to adjust them is a big deal.  I keep thinking I need the Micro MOA gas blocks...  One more thing, I shoot quite a bit and sometimes I can't get H335 or 8208 or TAC or... changing your loads can cause a need to adjust.  Almost none of my rifles will lock the bolt back with my hoser loads but I try and never shoot to bolt hold back. BTW, I am middle of the pack at best shooter so take all this as the words of a seasoned competitor not a pro.

    Not sure why there is so much whining about adjustable gas blocks sticking up. I have used them for years and never really had an issue I thought was serious enough for me to not take advantage of the benefits they provide.

    When you first get one, adjust it for your chosen set-up. If you do it properly, you will not have to adjust it again unless/until you make a major change to the ammo your using, or decide to change your spring/buffer/BCG combo.

    At that point, I just put a few drops of Kroil on the adjusting screw, let it soak in, then click it one click in both directions, after which it adjusts like a new one. I personally am a fan of SLR and have never had one fail or lock up that the above didn't fix.

    Lets say you adjust your gas block to an optimum setting for your rifle and match ammo in say Florida in august and you go and shoot say Benning in October... its now 37 degrees and you rifle will not run... I buy adjustable gas blocks so I can adjust them, not just a few times.  I have bought several different ones and I got sold on the idea that SLR Ti with a melonited screw was the best and least likely to lock up... total BS  $180.00 gas blocks and they seem to lock up more quickly than a 60.00 seekins...  I said something to this effect on IG and the SLR guys blocked me... They all seem to lock up but seriously if I go out and shoot 20 rounds and don't adjust it when I get home it won't move a week later without soaking it with some penetrating stuff and working with it. I also feel like after doing this several times the threads are getting jacked up in the ti.
