I see that the brake has the same angle as the guard.
Mine, gas block installed, everything tightened down. Still waiting on a gas-block, this will share my varmint lower, I like how it balances with the rifle stock. Only piece left is the bolt. Red dot is what I had laying around, will end up with a hunting optic on it Sent from my iPhone using Tapatalk |

I did get out late this afternoon for some test firing--fires beautifully--no brass scrapings, no damage to cases--very happy about that.
A few minor issues--the bolt lugs are a bit sharp and require a bit of force to unlock from the extension--my weaker hand-loads resulted in some short-stroking--but all the full power loads and all factory ammo I shot performed without problems. A bit of stoning of the lug edges and I'm sure everything will be just fine. The 90 gr nosler bonded base bullets I found were a bit broad in the ogive--I originally seated them with the cannelure beyond the neck mouth (extra powder) but still around 2.26. This resulted in the bullet jamming in the throat, a simple re-seat with a bit more depth into the case fixed that. The Radical Firearms adjustable block is a bit of a mystery to me--the one I received appears to be totally different from the one they advertise on their site--the adjust screw is on the side and the set screw in front--they advertise their block as having the adjust screw in the back and set screw on the side. Near as I can tell, the screws don't do much of anything at all--except perhaps make you feel the extra $25.00 you spent is literally worth time spent screwing around. If I didn't have my brake already installed and torqued down on the crush washer I'd take the block off and toss it, replacing it with a non-adjustable. Oh well, live and learn.

Thanks ed--(edited) i'm a big fan of gold dots in pistol loads. Doesn't look like 90 gr is all that much either way. I'm guessing the nosler penetrates better??

@temoniprince--thanx
@ed--I went to cavity back's site and checked the mags out--bit pricey but I may try one. I also noticed their bullets--have you tried them?

The quality of the window mag is excellent. The owner of Cavity Back Bullets (Yamaraja - Robert Bell) has done a lot of testing loading 130 gr bullets long in the 6.8. He's one of a couple of people who are pushing the 6.8 to the extreme and way past what it was designed for. You can see improved velocity and accuracy by loading out to 2.36. I haven't tried but will if I ever get to start back to the point where I'm shooting on a regular basis.
Regarding his bullets, I haven't tried them. But people of the 6.8 Forum have mentioned them and seem to like them for hunting. I've only read positive comments about them. Last edited by ed308; March 7, 2017 at 08:34 AM. |

Very cool--I remember "the gold old days" when SSA was pushing 130 and 140 gr 6.8 cartridges.
I went out again this morning to try testing my hand-loads--as my luck would have it as soon as I got set up it starting snowing hard; I had a choice--go home and come back some other time when conditions were better, or shoot fast groups in the driving snow and hope for the best. Of course, I elected to stay and take my chances. The 90 nosler tests were a bit disppointing, I generally couldn't get anything better than 2 to 2.5 inches, maybe good enough for close in work. The 110 accubonds were better most groups usually grouped in the 1 to 1.5 inch range--this was a fairly typical group: This was one of the better ones: I think I can do better in improved conditions (and hand-loads) and as the gun gets more "seasoned" but it's showing promise so far.

OK--so I'm sitting around after returning home--and it stops snowing--I still have some home-brewed SST's I want to try out, so I load up and head out again.
Of course, right after I get set up--it starts raining. Once again I decide to go through with the test shots, though I didn't really take measured breaks between the shots. Once again the results I got were better than I expected, most groups were right around inch or slightly more--and that was almost always due to me pulling one shot from what was otherwise a tight group. This was close to typical: While this was one of the better groups (it's the first group I shot after changing ammo type and weight--that's why POI isn't on a target dot). Overall given the lousy conditions and a relatively heavy 4.6 lb pull trigger--I'm very pleased with the results so far, this could quite possibly be my best AR build ever--not so much in terms of most accurate, but just how nicely everything went together or how beautifully it shoots--no signs of case damage or brass specks. The only very minor snafus were the gas block, which I just basically lock-tited to wide open--and a slightly sticky bolt which was easily remedied with a touch of stoning of the lugs. Much thanks to rick, ed and Wyo for forcing me under threat of bodily harm to buy an ARP barrel--very impressed so far and I'm sure I'm not even near what the real performance could be.

Those pictures of the targets tell me that that's a very deadly gun lol, once you and the get acquainted,it's gonna be amazing.
Thanks for sharing, in reality it was your 25-45 sharps that has me sitting here with a 6.8. The sharps got me to thinking about another caliber for the AR. Hours of research lead me to the 6.8. Convenience and intend use based on my hunting style finally got me to decide. |

Of course, now that you have a 6.8--you'll also have to build a grendel--if for no other reason than to be able to fight both sides of one of the great caliber argument wars. lol

Those groups show potential for a weather day at the range. And some are GTG for hunting. I'm glad you like it Stag. I've found very few people who don't like the way a ARP barrels shoots. I've replaced most of my AR barrels with ARP barrels. Hard to beat for price and quality.

It was posted on the 6.8 Forum as well. Didn't take long for PSA sell out. Check daily. They'll be back up there eventually.
