Magpul GENM2 MOE \ PMAG30 AR/M4 MDE
Just tested with all 3 of them empty, locks up 100% when empty and I wasn't polite with it.
I lube the BCG when I arrive while waiting for the range to go cold.
I'd be lying to you if I knew for sure as to how the casings landed.
At the range on Quintette Rd. in Pace each lane is divided by a section of fence.
95% of my casings land behind the person to my right. 430ish sounds spot on...
Happened with 2 identical Magpul mags *I have 3* that are stored empty and very little use. (There's just no way I have worn the springs out that quickly.)
It has to be something related to the 5.56 ammo or something with the gun.
I really wanted to confirm it at the range but I didn't bring...
10-4 I'll give it a thorough cleaning. I had already made plans to replace the adjustable stock with a fixed. (tube, stock, and spring) I have no use for the current adj. stock as I always set it at the max rearward setting any how.
Up until now I have only fed the rifle .223 and never had an issue.
I was at the range today firing 5.56 \ 55 gr and noticed it failed to lock into open breach the 1st time. (No FtF or FtE)
Didn't think much of it so I sent another 30 down, same result so I stopped and went to the pistol range...
I acquired a red dot for my AR but it didn't include a riser which makes it borderline impossible to use.
If you have one for a reasonable price please let me know. I only found 1 at a local shop but $50 feels a like a bit much.
*Edit: Also interested in an affordable bi-pod as well. Nothing...
