    AR Pistol over-gassing?

    Found the issue. The old barrel had an oversized gas port. Installed the new barrel today, adjusted the gas block and the ekection is right at the 3:30 position. Thanks for your input everyone.

    AR Pistol over-gassing?

    I didn't try those exactly, but I did try heavier bullets (64gr SSA by Nosler, 69gr Match PPU, and 75gr Hornady Freedom) that I had bought on sale a while back that I keep for testing. The groupings did tighten up with the heavier bullets, as you would expect. The 75gr was about nickle sized groupings at 25 yards, unsupported. Very good, but it would be too expensive for me to only shoot 70+gr ammo out of just this gun. The barrel I am looking at is under $200 with a 1:8 twist and a .223 Wylde chamber. So that will allow me to get similar groupings with 55gr ammo (since my 18" 1:8 .223 Wylde rifle does just that), and save money in the long-run.

    350 Legend by Winchester

    Yes Sir. I also found out that 350 Legend will require different mags. I think I may just stick with my AR-10 in .308 Win since I just solved the low gas and short stroking issue I was having. I was using a Superlative Arms Adjustable Gas Block on it, their design has a port vent to vent excess gas. Well, it was venting too much gas and short stroking. Replacing it with a Standard Gas Block fixed that issue.

    AR Pistol over-gassing?

    I agree with you Sir. With my current barrel, (8.5", 5.56 NATO chamber, 1:7 twist) the 55 grain has a pattern of 2" to 3" groupings at 25 yards. To me that is terrible. I found a barrel that I am considering to replace this one, it is a .223 Wylde barrel and I believe that it will preform much better. I could use heavier bullets for the 1:7 barrel, but they aren't as cheap as 55 grain. I am also thinking that the ejection at 2 o'clock to 2:30 issue that I am having may also be due to the type of gas block I used. I used a Superlative Arms Adjustable Gas block. My AR-10 had cycling issues with a similar one and when I swapped it out with a Standard Gas Block, the issue resolved and the rifle functions perfectly now. Superlative Arms' Adjustable Gas Blocks are designed with a port vent to "vent excess gas" from the system. In the case of my AR-10 it was venting too much gas and was causing short stroking. With my AR-15 Pistol, it may be allowing too much, not sure. But either way, I ordered a new adjustable gas block that is a closed system. We'll see how this works.

    Thanks, I'll have to test it out some more. I think I'm just going to change the barrel though. The 1:7 twist on this 5.56 NATO chambered barrel is just not holding the groupings I would like for it to with 55 grain ammo. The ejection problem might go away, who know with these things.

    AR Pistol over-gassing?

    Thanks. You're probably right. My H3 Buffer is about 5.5 ounces and I recently found another that is about 6.8 ounces. I figured this might put the ejecting brass right where I want it. But I definitely wouldn't go any heavier than this 6.8 ounce "H4" Buffer.

    AR Pistol over-gassing?

    I was playing around with it a bit today. The brass ejects now at about 2:30, I am guessing the cold is playing into that. The brass is not dented, but my extractor is sure chewing up the base. I did adjust my adjustable gas block down two clicks and this had no effect. I'll try again when I have more time.

    350 Legend by Winchester

    I hope so too. In theory just a barrel and muzzle device would be all that is needed. I would guess that it could run on a standard .223/5.56 Bolt Carrier. Only time will tell, but I hate waiting. lol.

    350 Legend by Winchester

    If this round gains enough ground for manufacturers to make AR barrels, I may just sell my AR-10 and build an AR-15 upper in .350 Legend. I think it would have to use different magazines though.

    Likewise. I am interested to see how this goes also. I contacted Faxon and they told me that they have had inquiries since Winchester unveiled it at Shot Show yesterday. Faxon said that they are passing it on to their production team. It may take off like the 224 Valkyre? ... I hope.

    Might not even need to reload. Winchester is advertising their 145 grain FMJs at about $9.99 for a box of 20.

    Right. It looks to be a shorter, rimless version of the .357 Remington Maximum.
  13. So, I built an AR Pistol with a PSA 8.5" Gov profile Barrel (link at bottom); it is Semi-Auto only. It does function fine, but I notice that my brass ejects at the 1:30 to 2 o'clock position. I have read several articles stating that they should eject anywhere between the 3 o'clock to 4:30 positions, or close to that. I am currently using an adjustable gas block and an H3 buffer with a SprinCo Red Extra Power Buffer Spring. Closing the gas block any further won't allow the carrier to lock open on a empty mag. I was thinking of purchasing an H3 buffer with a steel body, (some call this an H4 Buffer), to raise the buffer weight to about 6.8 ounces. Will this help, or is it even necessary?

    Winchester introduces a new cartridge intended for hunting. they call it the 350 Legend, introduced at Shot Show 2019. Basically they straightened a .223 case and fit a .357 round on it. Interesting .
