Yep. It's worked great in the past with other models as well as the .308s which have about 20x the tension of a 5.56 mag. There's a reason why the pins I choose have such a high shear strength.

I'm not too keen on loading against a closed bolt. Reason is the difference of a few thousandths of an inch plus some normal wear and tear on a mag results in a 16th round being able to be loaded. If loading against a closed bolt is that important, do what we free staters do and download your mags. I've never been in a carbine class where people load all 30 rounds after the first day. They might show up with 30 on TD1 but by the second day or even after the first break to reload, they're loading 28 or 29.

Well, I think that answers that then. I'll start working on something over the weekend.

Yes. The sides of the mag body are too slender to keep the baseplate on through tension alone when the spring is pressing against it.

The M revision (now known as Gen 2 or MOE) featured a slimmer ribbing than the original PMAG which allowed that

I'm kicking around the idea of cutting down MOE PMAGs so the bodies only take 15 rounds. The baseplates would still be attached with roll pins but you can drift those out and take the mag apart should you desire to. These wouldn't be welded shut the way 15/20 and 15/30 mags are. Cost would be in the $23-$25 range.

JoeBobOutfitters.com is now carrying 15 round limited capacity PMAGs made by Midwest PX. The owner, Joseph, is a personal friend of mine and runs an industry-leading operation. They received their first shipment of 15/30s and will be carrying 15/20s whenever I can get most host magazines in to modify. http://www.joeboboutfitters.com/15_30_MidwestPX_Magpul_M3_PMAG_Black_p/mwpx-1530m3blk.htm

Magpul has officially discontinued MAG243 and the replacement, MAG291, will not be cut down due to the floorplate design. So this is the last time I will have 15rd body .308 PMAGs available. Once this batch is sold out, they won't be coming back due to host magazines no longer being available to modify. Available HERE .308 15/20s based on MAG291 will eventually be available when I work out the new block length for the new design.

VLTOR's making Rainier's in AZ, I think.

It's in such an out of the way place though. If you want a reload on the rifle, Redi-Mod is the way to go, IMO.

Yep, it's a two piece design. One piece is 98% of the mass then a dovetailed smaller section on the underside is used to clamp it to the barrel nut. You don't need to cut the delta ring assembly off if you can remove the barrel nut.

If you're stripping it down to the factory barrel nut, I'd take a hard look at Fortis. They're lighter and integrate the new Key-Mod system while still offering a continuous 12 o'clock and 6 o'clock pic rails. At 3 and 9 o'clock, there are sections of pic rail at the front of the rail but Key-Mod the rest of the way down. Four limited rotation QD sockets, two on each side, one at the front and one at the rear plus anti-rotation tabs. And the 12" can be had for under $200.

7" Fortis weighs 6.7oz and you get to delete the delta ring assembly

What the image is describing is cut threads vs. rolled threads. Rolled threads are stronger as they interface more completely with the receiver extension. Cut threads are cheaper to produce. The very best receiver extension that I have come across is the Lewis Machine Tool six position extension. Forged 7075, rolled threads, dry film lube, nearly hydraulic feeling with the SOPMOD stock. They also cost nearly $50 each for just the extension but you're paying for quality. UTG surprised me with their US made extension. While it's extruded 6061 with a T6 temper, they rolled the threads. I've mortared a couple test builds before committing to carrying them and they held up.

Yes, the one on the right is real.

AU has been involved with counterfeit Raddlocks (CA bullet button), Accushots, and other products.

I've had hundreds of OD and FDE come through in the last few weeks so I don't think they're being discontinued. But with Magpul, nothing is for sure unless they put out an official statement.

My understanding is a red arrow means you may not turn right on red.

Short of there being local laws that would require the use of an FFL to transfer a firearm between two private parties, there is nothing illegal about selling a firearm to another private party without the use of an FFL. Obviously, handguns sold to a resident in a different state need to be transferred through an FFL in the buyer's state but one Missouri resident selling to another is considered cash and carry.

Minus ~$200 without the rail

There'll be updates here and there though what gets posted here will likely be more NJ-oriented than in general.

I must be really tired today if I can't get the URL to embed

I fought it for awhile but there are too many positives uses for Facebook to stay off it. Please like our page found here: http://www.facebook.com/pages/Midwest-PX-LLC/456802557766467 to hear about updates, new products, etc.

They're all high quality rails in every regard. The Fortis rails are lighter and fit my hand better so I prefer them to both the Geissele and Centurions. The CMR does have one drawback and it is that it is only guaranteed to work with Centurion gas glocks...pretty much anything else needs to be ground down to fit. Yes, eventually.
