Comes with upper

Do you have any experience with magwell blocks?
What keeps my attention with the quarter circle ten lower is the glock mags. Specifically the cheap magpul glock mags.
What makes me loose attention is the deticated to that caliber part of the lower.
Since I already have the SanTan lower SBDed, if a magwell block works well, I would just do that.

I use/carry a Glock 19 already, and would love the commonality of magazines.

Oh, for sure. I've have springsfields. So it makes me want to also get a glock. Lol.

New Frontier vs Quarter Circle 10.
Differences other than price?

Looking to get a 6920 OEM2 - does anyone have a good online source? My local shop wants $980 which seems pretty high.
I found this link earlier in the thread:
https://www.gandrtactical.com/cgi-bin/commerce.cgi?preadd=action&key=LE6920-OEM2
I've never dealt with G&R Tactical and online reviews seem to be mixed. Are they considered a reputable source?
quote:Bender and MTS6175, thanks for the suggestions. Got some advice that going to an 8 or 9 inch barrel could lead to reliability/cycling issues, which is one reason I was leaning toward the 10 inch. Any advice/thoughts on this?
No reason to go over 9" in 300blk IMO.
Most loads are designed to have burned all the powder by then, and the big advantage of the cartridge is the compactness....so I wouldn't bother going over that.
I really need to build a 300blk upper. One more project to get around to.
quote:Agreed
8 and 9" (really anything below 10") barrels can create cycling problems with the 5.56/.223 round.
As stated, the .300 blk was designed for 8.2 - 9" barrel optimization. You should not have any cycling issues attributed to the length of the barrel.
quote:You'll be fine with an 8" barrel on a 300BLK. Get an adjustable gas block so you can tune it between subs and supers/suppressed/unsuppressed. Have you seen Travis Haley's video on his year with 300BLK? It's from several years ago, but I still think it has some good shooting/info.quote:Bender and MTS6175, thanks for the suggestions.

Any knowledge of Yankee Hill barrels? They were recommended to me, but would love your opinion on the top 3-4 barrel manufacturers for this specific build.
It's out of stock but was looking at this one:

Thanks for the other suggestions as well, keep the advice coming.
quote:Mr Dubi hits 400 yard targets with his SBR.
Thanks for that info and the video, will take a look at home tonight. One follow up, if the cycling issues can be tuned with an adjustable block, that answers that question. Follow up though - what are the group's thoughts on barrel length for accuracy out to 150 yards? Will likely use this rifle to shoot hogs (not necessarily subsonic for that use). We are in mesquite and shooting lanes are typically only 150-175 yards max. Should I go with a 10 inch barrel for that reason? Was told by the local gun shop that an 8 inch barrel would likely only be accurate out to 100 yards and I should consider a 10 inch to reliable hit targets with 300 blk at 150-175 yards.
Thanks, I'll hang up and listen.
quote:Then they must not know much about the 300 blk round, because they've told you bad/incorrect information twice now regarding it and its abilities.
Nah they are good people, known them a long time and just as much friends w some of them as I am a customer. Cost between the 8 and 10 inch they sourced for me were essentially the same. Glad to know you feel that an 8 inch barrel will be sufficient out to 200 though! Music to my ears.
quote:I don't shoot mine much more than 120yd. 300BLK is not flat shooting at all. Take a look at some trajectory charts for both supers and subs. If you put in a lot of time with it and know your holdovers, you should be able to hit 200yd reliably, but I use a different caliber for that. The video I linked shows Travis reliably hitting steel targets at 800yd with his 8" 300BLK. His ammo budget is quite a bit higher than mine.

quote:So I was NOT reading carefully. Mr Dubi's SBR is not a 300 blackout; it is 223/5.56.
Awesome, b/c that's what I'm building. Is Mr Dubi's SBR an 8 inch barrel?
