Just curious why XM5 was using Lancer L7AWM instead of 7.62 PMAG20. Does anyone know inside scoop? Is Lancer mag with steel liner more durable for 6.8mm?
I was thinking Pmag is now USGI for 5.56 so procurement should be no issue. And XM5 uses Magpul SL-K stock, so Sig is also partnering with Magpul on XM5 already.
On the other hand, is Sig going to come up with its own M5 mags? Seems too lucrative of a procurement contract to give out.
I have heard issues with drag in the magazine on the 7.62 magazines for PMAGs due to the larger amount of recoil causing the tips of the bullets to eventually dimple the polymer, while the steel liner on the L7AWMs get past this issue. Never seen it myself, but I'm not a high volume large frame shooter, and I stick with PMAGs, due to the Lancer 25s having excessive spring tension (even after Lancer clipped off a coil for me for each of my mags) and the steel feedlips having more drag when dirty (which happens quickly in my suppressed SR-25), and thus not feeding after an empty chamber reload, as the round will only come out the magazine halfway when dropping the bolt.
I will also note that SIG and Lancer already worked in the past before for their MPX mags, so they certainly already had some kind of working relationship when it came to magazines.
According to a Sig rep, any existing 7.62 SR-25 style mag will work. Sig is in the process of designing their version of the mag for future sales. They just seem to have used the Lancer as an off-the-shelf option. Interestingly enough, the True Velocity NGSW offering also used Lancer mags in all of its promo material.
That's interesting to me... I had to polish the feed lips on my L7AWMs for reliable feeding, especially the first round on a full mag. I don't shoot my AR308 suppressed so I guess I'll note if the mags start to stick after X number of rounds.Quote:

from my experance - pmags didnt do very well in the heat of iraq. Cracked lips and deformation. That was my experance - no issues with OKAY surefeed mags. USMC 3/5 retired.
USMC (my platoon) was given surefeed mags- some guys tried pmags but switch back to OKAY after a short while. just like most of us switched our BCG out to BCM or LMT. Its like pulling teeth to get parts repaired or replaced. Especially M9 mag springs or recoil springs.
Interesting. I never had issues with PMags in the heat of Iraq or Djibouti. Can't say I've heard of widespread complaints about them in the heat elsewhere either.Quote:

It happened in the army as well. just like changing furnature - Some of us would switch to magpul stocks or grips and so on. i couldnt comment on the US Army - but in my experance getting anything repaired or replaced was difficult. especially springs in the weapons. the BCG in the rifles were the same ones you got in your Colt or FN out here, just a lot more wear and tear. I retired in june 2006 (I was issued the m16A4) and im sure things changed over the years afterQuote:

PMags haven’t given me feeding or breakage problems in DJ, where its ridiculously, stupidly hot at nearly all hours, or anywhere in Iraq or Afghanistan, to include the coldest and hottest places those countries have to offer. Or in any other dumb place I’ve been.
There's a helluva difference between swapping out a grip or buttstock with swapping out a BCG, and I had to fight to even get the buttstock/grips. Swapping out internal components would have been a huge no-no as "Unauthorized modifications." I get the frustration with worn-out weapons (the M4s we used in the 82nd were pretty damn worn out by the time I got there in '07, and we used them for years afterward before they got upgraded to A1s) but jeez, that's a definite culture difference.Quote:

I remember the big hoopla over them being released because every gun store around Bragg was pushing them, and a few guys thought they were the greatest things ever, and indestructible... until we ran one over with an 1151.
