Why Nemo
NEMO Arms builds AR platform rifles in Idaho, including the OMEN, the first production AR in .300 Win Mag. It uses a reduced recoil bolt carrier group to tame the magnum.
The rest of the line runs through the XO large frame, the Battle-Light and FX small frame ARs, the Mongoose 9mm carbine and a bolt action. Complete guns land around $2,900 to $3,850.
Parts include forged and billet receiver sets, Slim Grip M-LOK handguards and an ambi magazine release. That release sells for about $85 against roughly $30 for a typical one.
Availability is thin: in early October only about 26% of NEMO listings across stores were in stock. Parts cost well over the typical price in each slot.
We'd look at NEMO if you want a magnum AR that someone has already sorted out. For small parts, cheaper ambi options do the same job.
- NEMO built the first production .300 Win Mag AR platform rifle, and it has a recoil reduction system.
