Allen Engineering AEM-5 "Ops Inc. #12" Mk12 SPR Mod 1 and NSW RECCE collar - long

Ops, Inc. #12 model - long collar for Mk12 Mod1 as well as most NSW RECCE builds

Perfect replacement for Ops Inc. #12, fits AEM-5.  This is for the Mk12 clone build, as well any other great rifle build. This is the longer collar, which will fit the Mod1 and other SPR profiled barrels. 

Note:  This Collar will NOT fit the Mod0.  Here is the link to the Mk12 AEM5 short collar.  The long collar fits most builds, as long as the barrel is properly profiled.  The Mod 0 has a much closer clearance to the front sight base, and thus you will need a shorter collar.  Note:  Not every Mk12 or RECCE barrel is correctly profiled.  And some will accept the collar, but will not accept the suppressor.

Ron Allen builds these one by one by hand.  He was the engineer that created the Ops Inc. collar and suppressor.  Well worth the money for any precision 5.56 mm rifle build.  Ron created the collar while working at Ops Inc.  This is the exact same collar.  If someone wants to argue otherwise, you might find something where a roll pin is .001" in a different spot, but I have not found it.

This is 100% genuine Allen Engineering.  There are alot of companies making knock-off "Ops Inc" collars.  Even some rifle manufactures building very nice Mk12 rifles with the wrong brake and collar.  If you are not going to run a can, the knock-off or generic Ops Inc might work fine.  But for the small price to get the real deal, we do not work with, nor endorse any other manufacturer.  The tollerances to get the profile, collar, the threads, all in the right spot to align the suppressor are very tight, and Ron tells us he is seeing baffle strikes on his cans caused by another manufacturer's collar and brake, or a poorly executed SPR profile on the barrel.

Note:  this is only the collar and set pin.  For a complete installation, you will also need a brake and thread protector.  Allen Engineering brakes, collars and thread protectors.
