what Version of CMMG.300BLK is Ur Upper?…
(I got the same 1!, But I got mine Used with a Cheap Handguard So I'm Unsure What Version I Own?…) Until I Saw Ur Video!!!All New CMMG .300BLK UPPERS Have 1/7 Twist, Your N Mine Have the 1/8!…Does your Also have the WASP Coating?…
Anyways
Thx
My .300 Blackout SBR shoots better than that at 100 yards with iron sights… You might want to check your stabilization rate with the twist of your barrel, not sure what ammunition you are using, but the weapon is capable of that and more from my experience…
Do you have a problem getting subsonic to feed your blackout?
I currently own one of the uppers and I have had a lot a non feed problems. I had a box of Remington .300 AAC non subsonic, I was at the range last and it made me cry because I waited sometime to be able to go, and when I got there, some wold feed and the second wouldn't feed. It looks like a really tight bore, and I bought it with the complete upper, bolt carrier and charging handle. I'm thinking of having a smith look at it and see what the problem is.
What type of ammo are you using, I just built a 300 blackout and I'm using hornady ammo and I can't get a good group and be consistent
Thanks for the info – Charles
Check out PNW Arms. ammo, $130.00 (200 RD.) Range ammo 147 grain FMJBTtm bullet .300 blk
Nice shooting.
@newdefsys You'll Love it Ammo won't be in Local Stores I Ordered Mine Online But Now I got Enought Empty Cases to Reload – Charles
Wow, you just put the 300-BLK on my radar screen.
@crcooktube I reload reformed brass using 18gr h110 and a 130gr barrier blind federal bullet pulled from some military .308. The OAL is 2.050". This load is extremely accurate, but I think I will never be able to find those bullets again 🙁
@tfusel Thanks for stopping By I still waiting for a calm day to go shooting again. the only time it calm is when I am at Work. What ammo are you shooting? – Charles
Nice editing on the video… Shot camera in the upper corner was pretty nifty. I have one from DS Arms and that thing is a tack driver as your CMMG displayed. Best cost effective round for most effective civilian HD in AR platform IMHO.
@STICKANDTWIST1 Thanks for Stoping By I'm Glad I Made the Jumped and Got one They are backordred everywhere – Charles
