So regarding accuracy, Criterion 16" nitrided 1-10 twist ADM barrel shooting M118LR with the Aero bolt:
 The bottom group measurement got cut off so look to the right, the table is for that group. 1" orange dot. The not shown group is overall 1.4 MOA. These were pretty typical groups, one has 6 rounds because I can't count. Same deal, with the Fulton bolt:   I think if I slowed it down, that I could tighten those up. I shot them back to back and the suppressor was casting a bit of mirage on the last 2 groups. Anyways, not bad for a home brewed gas gun. Anyone need an Aero BCG? lol |

First couple rounds down range with the new 6.5 creedmoor build. It will not eject spent casing, to get it to eject takes a great force pulling back on charging handle.
Some specs are toolcraft dual ejector dlc bcg, 20" premium fluted barrel and 140 grain american gunner. Any ideas? |

Bullet itself has a spiral winding around it. Manually cycling it is smooth round to round with out mag in the well. Add the pmag and it feels gritty and binds up? Primer strike is mint, can get a pic of that as well. |

You eject the unfired round and it has rifling marks on the projectile? I’m going to go with the chamber being out of spec. |

Load dev on the 22" Criterion Creedmoor is starting to show promise.
 20200625_191154 by Professor Horseyhead, on Flickr  20200625_191209 by Professor Horseyhead, on Flickr Two good hunting loads. Gonna put together probably 20-30 of each and take the chrono next time so i can get velocities and make dope charts. Also have some 140 Berger Hunting VLDs to try. |

Quote HistoryQuoted: Correct. I double checked gas block alignment. Stumped. I would wager if unfired rounds are ejected with rifling marks on them that it has an out of spec chamber. The round is seated in the chamber with no freebore with the projectile forced into the lands and is likely causing over pressure. I’d send the barrel back, or take it to a smith and have it rechambered. |

Lol It’s groups decent and I like to shoot a lot so 1/2 the cost means twice the shooting. Only happened a few times first couple hundred rounds so not sure why it is happening more now. 5 shots at ~180yds with Tula 150SP, this stuff is similar. So not horrible for steel ammo and works well for critters.  Attached File |

I have two M5 lowers in my safe. Thinking about building one out into a suedo M110K1 wannabe rifle. Anyone have success in building one? As much as I'd like to stay 6.5CM like my other rifles just for the sake of ammo commonality, I think this will be in .308

I'm going out Friday morning (weather permitting) to take the first shots, adjust the gas block and sight in my recently completed AR-10/308...my first one! Build details here but my goals are to first confirm basic function and follow the directions for the Superlative Arms gas block to make sure it functions properly. All the while also following the Faxon barrel break in guidance:
4150 & 416-R QPQ Barrels Shoot once, clean copper out. Repeat this twice. Shoot five rounds, clean copper out. Shoot ten rounds, clean copper out. Finally, sight in the scope at 100 yards. Questions 1) I have some Atomic general purpose 168 BTHP ammo that I was going to use for the initial function, gas block and barrel breakin process. Then switch to either IMI 168 or 175 SMK style ammo. Sound good? 2) I was planning to sight-in using one of the two IMI ammos...any suggestions? Barrel: Faxon 16", Medium Tapered, .308 WIN, Mid-Length, 416-R Stainless QPQ 3) I'm open to any other suggestions/advice  |

Glad someone else got something out of it. I’ve been wanting to test this exact thing. Usually I’ll get a matched bolt from the barrel maker when I build a gun, but in this instance the barrel I wanted that was available at the time didn’t give me the option. A good dude I know who is smarter than me told me when he builds an AR he will test it with different bolts to find the one that shoots best. I’m thinking there is something to it. |

I got it on the initial sale from MidwayUSA for I think $725. If I ever started shooting longer ranges I wouldn't hesitate to get another. I just don't ever use higher magnification. |

I've decided to build a 6.5 creedmoor on an M5 receiver set. Can someone help double check parts compatibility and answer a couple questions?
My parts list so far: M5 receiver set Criterion DPMS pattern 6.5 creedmoor 18" hybrid barrel JP high pressure bolt (headspaced by Criterion) SLR Sentry 7 clamp-on adjustable gas block SLR 308H 15" Solo rail I'm going to use an Aero LPK and buffer+tube. These receivers will accept AR15 grips, stocks, and triggers right? Will the above components work together? The varying standards for AR10 parts has me a little confused. It looks like the JP bolt does not come with a bolt carrier, can anyone confirm that is the case? If so, who makes a decent bolt carrier. I'd rather not spend JP rifles money on the carrier alone. |

Are the M118 Pmags causing issues? I've seen a few reports that they don't drop free from the M5.
Do these things run on steel case? I'm probably going to use a BA 16" barrel but might go with a chromed Criterion. Not sure. |

You can use the enhanced rail with a regular threaded upper, but you have to use that barrel nut and time it for it to fit properly. With the enhanced upper it will screw right on. If you think you might change handguards at some point then the threaded upper could make sense. |

Looking for hunting loads for around 200 yards and also target loads for up to 500 or so. Quick update, I got to take this to the range today. The rifle ran flawlessly with some cheapo 150ish gr (just to get on paper) and then 168gr Federal GMM, though the compensator is a bit....much lol. I had a divider right next to me which was making me feel the pressure coming from it quite a bit. Just happy it didn't have cycling problems though. I love it! Accuracy.....let's just say I have some fundamentals to work on before I go pointing fingers. |

I really only plan to ever use it from a bench or a blind, feel free to let me know anything that I did that was horribly dumb lol https://i.imgur.com/ewkicGF.jpg Aero Complete Upper - M5E1 with 18" 416R stainless barrel: 1:10 twist I think? Aero BCG - Black Nitride Aero Stripped M5 Lower Aero M5 .308 Carbine Buffer Kit Aero LPK Larue MBT-2S Trigger Radian Raptor charging handle - The cheapo one I bought from Aero was really fucking hard to operate for some reason. Raptor feels great. Magpul STR Stock Magpul MOE+ Grip Vortex Viper PST Gen II 5-25x FFP scope w/ MOA reticle - Not gonna lie, I think this is too much scope.....I went with it because it was only $100 more than the 3-15 Vortex QD 2" Cantilever Mount Magpul bipod (I have a Harris I can put on but I wanted to try one of these) Precision Armament M4-72 .308 Compensator Any recommendations on which factory loads will likely produce the best accuracy?

I'm trying to figure out if I want a 14.5" 6.5, kind of like a M110K1 type setup to go along with my 18". I don't own any .308s so I don't want to add another caliber to my stable

This may have already been asked and answered in this thread, but what are people using to assemble their uppers? Looking hard had the Midwest upper rod, but saw a few positive things about the plastix blocks.
