[ARCHIVED THREAD] - SOPMOD stock (Page 1 of 2)

Does anyone have the info on who came up with the SOPMOD? I was told LMT but then it looked like it was a Naval Patent?  |
|
LMT did not design the SOPMOD stock, they licensed it for commercial production from the Navy (Crane). Any SOPMOD stock produced to the mil spec, under license from the government, is very much legitimate. http://www.thefirearmblog.com/blog/2011/06/06/army-buys-sopmod-ar-15-stocks-for-just-12-28/ |

Copied below from some B5 promotional write up. No clue on accuracy. The original SOPMOD Stock was created by the Crane division of the Naval Surface Warfare Center (NSWC) in Crane, Indiana to help better serve America’s premier warfighters. It improved upon the standard collapsible M4 (AR-15) stock by increasing the cheekweld surface area and included water resistant battery storage compartments. This improved stock was originally made available to Special Operations forces and has since trickled into other channels including the civilian market. Anyone who has used a SOPMOD stock can testify to its comfortable use and tight fitment on Mil-Spec diameter buffer tubes. While the first SOPMOD stocks were made in-house at NSWC – Crane, Lewis Machine Tool (LMT) later took up the job of manufacturing the stock for military as well as commercial consumption. LMT’s newer version stocks include quick-detach (QD) sling swivel mounts and a more secure lock up. LMT’s commercial MSRP for the stock is $199, making it a rather pricey option when compared to other aftermarket stocks.

| I like my B5 modstock a lot except for the amount of rattle when it's at the end of the Milspec receiver extension. How do I quiet it down? My Magpul CTR doesn't make nearly as much noise, but it's on a commercial receiver extension, so swapping the two around involves interchanging the entire lower. |

I bet someplace near Titusville FLA actually doing that work...... |

I've only ever seen it used on the rifles that came with my 12" GI Joe.

So they basically added a shotgun rib, neat.
The rifle with the funky removeable handle has an interesting FSB, or at least, a non-standard version. |

Quoted: I wish the VLTOR E-MOD had the tight fit and rotation limited QD sockets of the SOPMOD. That would be perfect. I love the SOPMOD on my SBR but the E-MOD is better for a rear bag and the extra storage, butt angle and toe cap is nice. EMOD rips out my operator beard. SOPMOD FTW. |

I would be super pissed off if my SR-15 had come with a Magpul stock. Quoted:
Quoted:
The KAC website shows stock images of their M-MLOK SR-15s with cheap MOE stocks. When I ordered mine, I was pleased to see the SR-15 came with a real-deal SOPMOD on it. I would be super pissed off if my SR-15 had come with a Magpul stock.

Quoted: The KAC made ones are superior to the B5 ones. Ask B5 about the pallet load that got rejected. When did KAC make SOPMOD's? IIRC B5 was given the wrong specs for the first batch they delivered to the .mil and then the defective tubes got dumped cheap to civilians. |

Where does LMT make SOPMODS? Have they ever made them in house? Do they even have the capability in their IL shop? There you will find your answer. |
