About Our Parts

We’re an all-American company committed to using the best materials and most advanced manufacturing processes to produce premium quality parts. Every component we make is rigorously torture-tested to failure and thoroughly evaluated for accuracy. We then benchmark our parts against the industry's so-called top brands—and ours consistently meet or exceed their performance.

At Spectre Supply we proudly stand behind everything we produce and challenge anyone to find tougher, more precise hardware. Other companies pour money into packaging and marketing, then make you pay for it. Instead, we focus on quality manufacturing and passing the savings to you.

Additionally, we source factory-original overstock parts through Non-Disclosure Agreements (NDAs) with major OEMs. These parts may include markings from well-known manufacturers like Colt, Para-Ordnance and others. Some may be unstamped, but all come from surplus inventory due to overproduction. 

Our business model lets us offer top-quality original parts at aggressive prices. However, availability can be unpredictable—once a part is gone, it might not be restocked. If you see something you need, don’t wait.
