AR15 PMAG Vs 308 AR LR20 PMAG
One of the subjects that often confuses shooters about the AR15 and 308AR is the size differences in the platform. We often hear “Can I shoot .308 in my AR15?” and the answer of course is no. I think one of the easiest way to illustrate the reason why is with AR15 PMAG Vs 308 AR LR20 PMAG size comparison. In the picture above it’s easy to see that the larger .308 Winchester cartridge requires a larger receiver, chamber and of course a larger magazine. A 308AR magazine cannot fit into the magazine will of an AR15.

Magpul Sand PMAG 20 LR Magazines
**DISCONTINUED”
Magpul Sand PMAG LR Magazines – Magpul quietly introduced a new “Sand” color to it’s outstanding line of AR15, M4 PMAGS and PMAG LR/SR 308AR AR-10 Magazines. The Magpul Sand PMAG LR Magazines for AR15 and M4 platforms are in the following capacities:
- 10 rounds PMAG 10 AR/M4 GEN M3, Sand Mfr Part: MAG559SND
- 20 Rounds PMAG 20 AR/M4 GEN M3, Sand Mfr Part: MAG560SND
- 30 Rounds PMAG 30 AR/M4 Gen M3, Sand Mfr Part: MAG557SND
- 30 Rounds with Window (Maglevel) PMAG 30 AR/M4 Window Gen M3, Sand Mfr Part: MAG556SND

The next-generation PMAG 30 GEN M3 is a 30-round 5.56×45 NATO (.223 Remington) polymer magazine for AR15/M4 compatible weapons. Along with expanded feature set and compatibility, the GEN M3 incorporates new material technology and manufacturing processes for enhanced strength, durability, and reliability to exceed rigorous military performance specifications.
While the GEN M3 is optimized for Colt-spec AR15/M4 platforms, modified internal and external geometry also permits operation with a range of additional weapons such as the HK® 416/MR556A1/M27 IAR, British SA-80, FN® SCAR™ MK 16/16S, and others.
Similar to the MOE PMAG, the GEN M3 features a long-life USGI-spec stainless steel spring, four-way anti-tilt follower and constant-curve internal geometry for reliable feeding, and simple tool-less disassembly to ease cleaning.
In addition, a redesigned bolt catch notch in the rear of the magazine provides increased bolt catch clearance, while an over-travel stop on the spine helps ensure the magazine will not over-insert on compatible weapons. Low profile ribs and new aggressive front and rear texture gives positive control of the GEN M3 in all environments, and a paint pen dot matrix has been added to the bottom panel of the body to allow easy marking by the end user for identification. The new, easy to disassemble flared floorplate aids extraction and handling of the magazine while providing improved drop protection, but is slightly slimmer than before for better compatibility with tight double and triple magazine pouches. An included pop-off Impact/Dust Cover can optionally be used to minimize debris intrusion and protect against potential damage to the top cartridge during storage and transit.

Vortex Viper PST 4-16×50
One of the greatest new features gained from updating 308AR.com is the ability for guests to add comments and even contribute content. This post will be the first in hopefully a series if not a standard operating procedure for this site. To kick this off I’m going to start with a question. What are your thoughts and opinions on the Vortex Viper PST series of scopes as well as Vortex Optics in general? Typically when looking at scopes for .308’s I will go with Nikon M-308 for low to moderately priced options. When I need premium quality rifle scopes I opt for Leupold Mark 4 ER/T series. Anyhow the last couple of years I have noticed that Vortex Scopes seem to get quite a bit of love on the web and now that we have a need for a scope or two for a few different 308 AR projects I figured it’s time for some public opinion.
For reference, the Vortex Viper PST 4-16×50 FFP Riflescope with EBR-1 MOA PST-416F1-A is the first of the Vortex Scopes I am considering.

Luth AR MBA Stock
Luth AR MBA Stock 308AR
Luth AR MBA Stock FDE 308 AR
At one of our sister websites MODULARRIFLE.COM there is a project to build a Remington 700 based MDT TAC21 rifle. Part of the process was to select a buttstock, something lighter than a MAGPUL PRS. One of the candidates that came in to view was Luth AR MBA Stock. The Luth AR MBA Stock appears to be in appearances, not construction or materials, an inexpensive skeletonized version of the MAGPUL PRS. I think it’s a great concept and initial reviews on the web are pretty decent. Magpul should take notice.
Note: Clicking either picture above will take you to two different resources for more information and purchasing options. It also helps support this site while costing you nothing.
