ErikS Wrote:Was gifted a 6.5 Grendel, BCA, 16inch 416R, M4 Profile upper by my wife.
The upper appears to be properly assembled. The bolt is MPI inspected. Staking is evident and touches the screw heads. The nitride finish is really slick but the inside of the bolt carrier is not chromed. The gas key is chromed internally. The firing pin retaining pin was a pain to get back in. New bolt and all
It fits my PSA lower as it should. The feed ramps are not pretty but match the upper "300BO" cuts in the upper.
The FFT is stiff and fits very well. It rings when tapped so I most likely will wrap it with parachord before hunting with it next season. The A2 birdcage is properly clocked.
I do see some red loctite on the visible set screw. The visible screw can be checked without removing the handguard. The other 4 screws are out of view.
The upper was obviously test fired using steel case Wolf even though they dont condone using it.
The barrel extension is crude but works. I shot 12 rounds or 123 SSTs through it last week just to get on paper at 75 yards. I will be at the range as soon as the snow at my place melts off. I shot it using PMags only loaded with 8rnds and it cycled fine. All brass landed at 3:00.
I posted this on another forum also.
I will post range results when I get out to shoot it. It will be after the holidays.[ATTACH=CONFIG]10685[/ATTACH][ATTACH=CONFIG]10686[/ATTACH][ATTACH=CONFIG]10687[/ATTACH]
After 35 rounds it started shaping up, .75 MOA with 123 ELD-M and AR-Comp. I will need to get about 150 rounds through it before I have a good idea really how well it will shoot.
I loaded up some more and may have a chance, again this weekend, to take it to the range this weekend. It is already deer killing accurate.
What type of rifling is bear creek using? I see 5R specifically labeled on some barrels, and others without. Does that mean they make a standard 6 groove and 5R?
I am specifically interested in this upper and the rifling used.

Yes, both, but the majority of their barrels have conventional rifling. If it's 5R it will be marked.

Got a Bear Creek 5.56 complete upper 16 inch parkerized 4150 1 in 8 wylde .223 for $216 shipped with military discount. The lower from Palmetto arrived yesterday tomorrow may be a range day will render report if it happens

Short-throated like mine was, but I hit the lands with OAL @ 2.234" with a 120 Nosler BT.
Just dropped my upper off at UPS on its way back to BCA to put the throat to spec so that factory ammo could be loaded without being jammed 0.011" into the rifling.
Well I can report on a BAD BCA upper I got. It averages 5" groups at 100 yards. Every shot seems to be a flyer so I suspect that the crown on the barrel is bad. I have called 3 times trying to get them to send me a UPS pick up ticket. After two weeks of waiting I called again today. Was told they were sorry but the person in charge of warranty stuff has been sick. I guess NO BODY ELSE could do her job. I was told that she would be in tomorrow and would call me. We will see.

Sorry to hear you apparently got a lemon. Which upper did you get?
I got the 20" SS fluted M-lock. It functions great, only have had one mis-feed and that was the second round in a new ACS magazine but after that it ran fine with both ACS mags and a Elander. It just shoots 5" groups and every shot acts like a flier. No two shots with in 3 to 5 inches of each other. The chamber seems OK from looking and measuring the fired cases and by just looking down the bore with a light I see no problems but the crown looks suspect. I really can't inspect the crown without taking the flash hider off and I am not doing ANYTHING like that or it may give BCA an excuse to void the warranty. If I do not hear something from BCA by noon today I will be calling them AGAIN. You live and learn. Since I have so much invested in ammo, reloading dies, magazines etc. I will be building another 6.5 Grendel since I just got a great deal on 3 Anderson stripped lowers. May just get the Odenworks combo that joboboutfitters.com has, Barrel, bolt, adjust gas block for $418 sounds like a good deal.
I bought a BCA complete 16" upper(now cut to 12") and a 18" barrel(that I assembled) and both are shooting great. Would not hesitate to buy another. I might build one with the 16" contour fluted.
I had terrible accuracy for the first few dozen rounds. I thought it was the crappy Wolf ammo. I switched to the hunting ammo and the groups got very good. Then going back to Wolf, those are reasonably accurate now too. I've never believed in break-in, but something happened. Could be any combo of cleanings and such too.
What ammo are you using? I'm also finding that one high end round is far better than another.

Yeah, and for me, it was kind of like a light switch. Suddenly good. It just coincided with switching boxes of ammo, so it made me think it was just the ammo at first.
