Drop free

[themonk]

Question to the group - Midway through 2017 is it acceptable to make lowers where Gen 3 pmags don't drop free?

[Mysteryman]

It's never ok to produce a lower so out of spec that mags don't drop free..

What is the lower in question? I'm having the same issue, but suspect it just needs broke in. Mine is an Anderson lower with @500 rounds down the tube.

Iirc some lowers don't drop free from lowers that are in spec. It's rare but I think there was a thread here about a bcm that did that some time ago.

[themonk]

The problem in the BCM thread was the over insertion tabs were causing the mags not to seat on a closed bolt.

Many lowers adhere to the MilSpec dimensions of USGI mags(aluminum) not to MagPul mags. I would have more of an issue with USGI mags not dropping free but that's just me.

[markm]

It would not be an issue for me.

[Eurodriver]

No it is not.

I would not own a lower that failed to drop free PMAGs.

[Wake27]

No it is not.

I would not own a lower that failed to drop free PMAGs.

Agreed. I sold my first AR which was a factory gen II Noveske, due in part to PMAGs not dropping free. Fast forward a few years and I was pretty bummed when my new factory Noveske (gen I) still wouldn't drop free with anything but GI mags. Then Magpul released the gen M3s and all was right in the world.

I have a lower that doesnt particularly take kindly to GEN 3's. It could be that batch though, I bought a bunch when my lgs was selling them out of the shipping boxes for like $8 a few years ago, which might explain something. I have some 20 round gen 3's that drop fine though.

99% of my gen 2's work fine though, which is odd because it seems that GEN 3's fix most ppls issues.
