What magazine works well with your .350 legend upper? I'm have feeding problems using both CMMG and Duramag 10 rd magazines for .350 legend.

I have found the lancer mags to work pretty good so far.

If you dont own a dremel yet....you should. Look up "AR feed ramp polish job" on youtube and try that. I have 2 BCA uppers in 7.62×39 and polished the feed ramps on both and they both work perfect!

I don’t own a .350 legend from here. I think after this last purchase, I won’t buy from them again if they keep me waiting for my recent order. Shipping times take way too long here. Their customer service doesn’t return phone calls and it’s very hard to get someone on the phone. PRIMARY ARMS and even PALMETTO STATE ARMORY ship much faster. Many times within the next business day after you order. This place will make you wait up to 14 business days. Which is basically three weeks. Just saying
