Is it just me or have others found they dont work? All 4 wouldnt feed in my AR, either couldnt feed the first or certianly never got past no2. The spring seems way to strong in them jamming them so hard against the lips the bullet wont feed out. The stag's 5rnd mag fed 200 rounds of different makes almost flawlessly (except for the first round on the barnual's each time).
So I send them back?
Pull them apart and cut the springs down
Good idea, seems the spring is really strong on them. Dremel will get a work out I guess.
Sorry to hear your having issues with them too @steven
Will be keen to hear about any breakthroughs you have since I've got four of them. Thought it was just me! ☺
Have you had a look in these?

I have a few, they're pretty hard to marry with the rifle when the BCG is forward. Other than that I don't think I ever had a malfunction with them. BTW, you can grind down the follower spring tail and fit 6-7 rounds in them.Quote:

Spear mags are way expensive, in fact all mags here are.
None of the black Spear mags will drop from any of the brands of receivers I have.
Mate sent a bunch back for that reason.
Yeah nah...
I had the same issue, had to go for the clear ones
even the clear gen2 ones didn't drop free for me until I ground some bits off
I got 3 of the desert tan Spear mags and they work fine on my Stag Arms.
So maybe I'll order some more stag mags, at least that works flawlessly in 200 odd rounds.
Maybe try changing the followers to anti tilt (Magpul).
The followers on the John Marsen ones are crap, I swapped them to Magpul anti tilt and have zero issues.
The Magpul 7/10 magazines are great, same price as the Spear when I've seen them
In regards to seating a magazine with the bolt forward. As most of the diminished capacity magazines ensure that no more rounds can be inserted than the stated 5 or 7 for legal reasons, there is no extra compression available to lock the magazine in place. With standard capacity magazines, you can usually insert 1-2 rounds more, this extra compression allows the magazine to lock in place. One of the reasons that GI mags are often recommended to only be loaded to 28rds is that they lack that extra compression.
I ground off 2.5 turns eventually (1 then 1/2 each time), on one it would then usually feed 2 if 2 were loaded, if I loaded 5 it jammed on the first then tilted on the 3rd. So I could take out yet another 1/2 turn but it seems to be tilting now and jamming up ie a different fault. So I munted several cases in the process as the BCG came forward, ho hum.
:(
I assume shipping a gun part back to Brownells ie into the USA is simply a non-starter?
I have complained, lets see what transpires.
I certainly need at least 3 reliable mags.
:/
Send one to me and I'll tell you if it's fucked
Magazine release:
I bought 1x spears Gen2 mag for fun and it seems to drop freely from my Spikes lower, have not tried it in my NEA however...
Magazine feeding:
I also have a number of AR stoner mags, i have converted a few 10 rnd ones to 7 round, and they seem to be much more forgiving than the 7 rounders (5 round ones modified).
This is because they still use the orginial full height springs, but i have fitted a fixed spacer which limits the travel of the follower so only 7 rounds can be fitted.
The factory 5 rnd (NZ modifyed to 7 rnd) use a tightly wound or stacked spring as the way to limit the number of rounds, but they keep the same wire size and coil pattern for the upper half, and this i see it is the problem.
As this recipe means the spring is actually significantly more stiff for the same duty.
I think the best thing to do with these is change the springs to the 10 rnd ones and then reduce the follower travel to allow only 7 rnds.
