Grey Ghost Precision
Grey Ghost Precision builds match-grade upgrade parts for the platforms most shooters already own — stainless steel barrels, optic-cut slides, and billet AR receivers — designed by a team with deep military and manufacturing backgrounds around one standard: accurate, reliable, and attainable. Impact Guns carries Grey Ghost’s pistol and rifle component lineup along with their range bags and cases, for shooters upgrading a Glock, Sig P365, or AR-platform rifle rather than buying new.

Grey Ghost Match-Grade Barrels: Glock 17, 19, and Sig P365
Grey Ghost’s 416R stainless steel barrels with a black nitride finish are machined to match-grade tolerances for the Glock 17, Glock 19, and Sig P365 — a direct drop-in upgrade over the factory barrel for shooters chasing tighter groups without changing anything else about the pistol. Because these are precision-fit replacements rather than universal parts, always confirm the exact generation your pistol is (Glock Gen 3-4 barrels don’t fit Gen 5 slides, for example) before ordering.
Optic-Ready Slides: Adding a Red Dot Without a Gunsmith
Grey Ghost’s stripped slides come pre-cut for the RMS-c and ROMEO ZERO optic footprints on the Sig P365, and Docter/Noblex-pattern cuts on Glock 17 slides — a way to add a red dot to a pistol that didn’t ship optics-ready, without sending the slide out for a custom cut. Slides ship with a G10 cover plate for when you’re not running an optic, so the milled cut doesn’t sit exposed. This is a slide-only purchase; the barrel, internals, and frame from your existing pistol carry over.
AR-15 and AR-10 Billet Receivers
Grey Ghost’s billet lower and upper receiver sets are machined from a solid block of aluminum rather than forged, giving a more consistent, tighter-fitting final product with distinctive styling cues over a standard forged receiver. The AR-10 receiver set is multi-caliber rated for .308 Winchester-based builds, with a flared magazine well for faster reloads under pressure. Pair a Grey Ghost receiver set with the rest of a custom AR build, or drop it into an existing parts kit.
Complete Grey Ghost Rifles: The HEAVY .308 MKII
Beyond components, Grey Ghost also sells complete rifles like the HEAVY .308 MKII — a 16″ match-grade-barreled .308 Winchester AR build with a Superlative Arms adjustable gas block and a Timney single-stage trigger, aimed at shooters who want the precision-parts philosophy in a ready-to-shoot package rather than assembling it themselves.
Grey Ghost Gear: Cases and Range Bags
Grey Ghost’s 500D Cordura range bag and padded rifle and pistol cases round out the lineup for shooters who want their transport gear to match the precision-parts aesthetic of their build, with practical touches like reinforced zipper pulls and dedicated compartments sized for a rifle or a pair of pistols.
Frequently Asked Questions
Will a Grey Ghost Precision barrel fit any Glock 17?
Grey Ghost barrels are generation-specific — confirm whether your Glock 17 is a Gen 3-4 or Gen 5 before ordering, since the barrel and slide fitment differs between generations.
Do I need a gunsmith to install a Grey Ghost optic-ready slide?
No — the slide is pre-cut and ships ready to accept your existing internals from the factory slide; most shooters can swap it themselves with basic pistol disassembly tools.
Is the Grey Ghost AR-10 receiver set compatible with standard AR-15 parts?
No — AR-10-pattern receivers use larger, .308-length components; standard AR-15 parts kits are not interchangeable with an AR-10 build.
