Do you have the magazines for this caliber
So I can use a basic AK47 magazine in a standard AR lower receiver? Or do they need to be modified?
Heavy spring,Enhanced pin , Good mags. Done
Can you use any AR15 lower with this upper? Or do they make specific lowers for this round.
Do you have a lower and upper kit. I’d like to build a commifornia compliant.
Will the sylvan arms folding adapter brace work with this?
i can testify bca is fire plus they are beautiful rifles. where else are you going to get a side charging 308 upper for less than 300
I like the upper assy but mine never operated right when I got it could only fire one round with out jamming I contacted bear creek multiple times and never heard back. I like the upper but had to replace almost all the bear creek parts to get it to function
What buffer should I use?
What buffer weight
Are your barrels . 308 or . 310 ?
do grendel magazines work?with 7.62 x39
I'm about to purchase a 762×39 16 inch rifle, how is the extractor holding up
Nice
Still working out issues on my AR47 from bca. Have changed ejector spring, timney impact trigger, heavier buffer weight. Have checked gas block and everything. Still not consistent. Used brass and steel case same issue.
How well would these side chargers work with a suppressor? Looking into a 16” and want to run a surefire can down the road.
You forgot to mention heaver buffer works best because of the overgas
Thanks BCA. I just got done building a lower for one of your 20"HBAR 5.56 uppers. It works great BTW. Now it looks like the 7.62×39 side charger is going on the list!
Mine didn't come with a Enhanced firing pin I had to purchase 1 , mine about a year old , on my 4th extractor, and now my bolt is getting stuck in the feed ramps in the upper, have maybe 600 rounds through it
I think it would be great if you offered a pencil and lightweight profile barrel in 7.62×39!
I ordered one after this video
the future soulder pistol,developed better the rifle
WHAT MAG DOES IT TAKE?
Is that a nice strong barrel?
Hey BCA team! Do you guys sell the side-charge BCG separately? I'd love to pick a spare one up for my 16" side-charge upper. Thanks
ARE THESE AVAILABLE IN CALI 2022?
I have BCA 16" uppers in 6.5 Grendel and 7.62×39 and I like them both but the 7.62 upper I have is a bit weighty. Does BCA offer a light weight 7.62×39 upper?
cual lower se utiliza Para este rifle 308 0 5.56
When we buy the gen 2 side charge upper, does it already come with the enhanced fire pin? Or do we have to source it somewhere else? In the description says it comes with it but in some of the comments, others say to get one.
Thanks for the information on the steel ammo and their harder primers, I was not aware of that.
What magazines are you guys using
Next build is a 7.62×39 BCA "pistol"
Pretty excited about it
Will the 7.62 upper work on a standard ar-15 multi caliber lower?
Are these rifles piston driven?
Been wanting to invest in my ar lately.. Also have been wanting another deer hunting rifle. I think I just found a universal answer.. Keep a nice fat scope on that upper, and a light weight red dot setup on my 5.56!
