Strike Industries SIDEWINDERIIBK Sidewinder II Black Back Up 45 Degree Offset
The Sidewinder 2 is the next evolution of our Sidewinder back-up iron sights. After receiving feedback from competition shooters and military personnel in the field, the sights have been upgraded to easily handle not only 5.56 but larger calibers as well as harsher environments. Keeping our same design concept, the Sidewinders offer the on the go option for 45 degree offset or traditional in line capabilities all in one package. Tool-less adjustment dials allow easy sight adjustments. Whether you need a low profile, low snag inline backup for your red dot or a short range, offset CQB sight backup for magnified optics, the Sidewinder can fill your needs. The low-profile SI-Ambush mounting system can clear even the largest of optics and the offset sight means instant access to your back up iron sights without removing your optic. Do not exceed 15 in/lbs (1.69 nM) for the Picatinny mount screws. Sight adjustment based on system length 0.50 MOA for 14.5" sight radius, 0.30 MOA for 20" sight radius. Rear apertures sizes 1.38 mm for small, 3.5mm for large.

Perfect daypack for everyday carry

I’ve been using this backpack as my daily carry bag, and it’s absolutely brilliant. Compact, tough, and surprisingly spacious for its size. It fits my water bottle, lunch, tools, and even a small tablet with no problem. The MOLLE webbing makes it super customizable. Can’t recommend it enough for urban or light outdoor use!

Serious gear for serious adventures

I’ve used this backpack on multi-day treks and it’s a beast. The build quality is outstanding—everything from the zippers to the straps feels durable and reliable. The side pouch system and internal organization make packing efficient. It’s the best large pack I’ve ever owned for backcountry trips.

The ultimate load hauler

If you need a pack that can handle serious gear and harsh conditions, this is it. I use it for hunting and winter expeditions—it swallows everything I throw at it and distributes weight beautifully. The modular design lets me adapt it to any mission. Truly a professional-grade backpack.
