Last question, I think I need to polish the feed ramp cause I’m having a hard time getting it to feed. And these magazine seem to be too tall because the carrier group catches on the magazine follower. Any tips or ideas to fix this?

Thanks again everybody!!

As @The Guide says, the bolt hitting the follower is really just an AR issue. ARs in their normal configuration have the follower pushed down and more out of the way by the bolt release upon bolt closing. Personally, I just don't run the bolt over an empty magazine.

I have a post on here about working on the barrel extension to smooth feeding; try searching "feed ramp" in this thread. That's another issue particular to ARs. Gassers get past it with brute force and acceleration from the buffer spring, but it becomes very apparent with manual cycling.

I actually first noticed it on my gasser build putting gouges in the bullets which I'd see when I'd extract a cartridge without firing it. Letting the bolt carrier go forward slowly while holding the charging handle made it pretty apparent as to what was happening. That was actually the first one I worked on. I now clean up all 223 barrel extensions regardless of what they're going on.

Has anyone built a 6mm max yet? I wonder if extraction is acceptable since the ARC is really tough

Not that I've seen, but it would probably be a great cartridge in these. Seems like they're holding the 6mm Max too closely to let it get any kind of momentum anywhere.

Someone at my range shoots one, I've picked up about 100 pieces of brass the last 2 times I've been there. I might look down that rabbit hole...

I like the lancer L5 mags and 16 inch 223wylde barrels to push a 77tmk at 2750fps.

Yea I realized the more I studied it out I definitely am going to have to polish the feed ramp on that barrel. And everybody was 100% right, as I didn’t notice initially that it was getting stuck on the magazine follower. So thank you again to everybody helping me figure out these problems. I’m super excited to get started on my next. Just need @hereinaz to get those 6x45 barrels done

I am getting closer! Working out the smallest/lightest barrel possible.

How’s she shoot?

It was getting dark and cold, so after a quick sight in this evening, this is the 4 rounds at 200 yards I had time for.
