Good stuff. Works as it was intended too.
Awesome retailer, buy with confidence.
Great price, fast shipping. Sticker is always a bonus
Works as expected.
It’s a genuine G barrel wrench. That about all I have to say about that.
Expected nothing less from Milpsec Retail, always fast and free shipping on genuine parts and accessories.
Was more excited about the conversion kit that came with it.
Thanks again MSR.
