Description:
Guns Listing ID: 558639
CMMG Banshee MkG 100 with Holosun HS510C Red Dot and Magpul sights – .45 ACP – Used, Excellent, Low Round Count
Manufacturer/Model: CMMG Banshee MkG 100
Caliber: .45 ACP
Action: Semi-auto, Radial Delayed Blowback
Configuration: AR-pattern pistol, Glock-mag compatible (MkG)
Condition: Used – Excellent (low round count)
Item Overview
CMMG Banshee MkG 100 in .45 ACP. This is CMMG’s Glock-magazine variant built around their Radial Delayed Blowback (RDB) system, giving you soft recoil, reliable feeding with .45 ACP, and a lighter overall carrier group compared to straight blowback .45 builds. This example is clean, well-cared-for, and shows minimal handling wear. Bore is bright; crown is sharp; controls are crisp. Low round count—just range function checks and a couple casual trips (no classes/abuse).
Notable Features
Radial Delayed Blowback system reduces felt recoil and bolt mass vs. typical .45 blowback AR pistols.
MkG Glock-mag lower – feeds from Glock 21/30-pattern .45 ACP magazines (readily available).
Factory pistol-length barrel (threaded .578x28 for common .45 muzzle devices/suppressors).
Free-float M-LOK handguard for accessories (light, sling QD, hand stop, etc.).
Last-round bolt hold open tuned for Glock mags.
AR-pattern controls (familiar manual of arms, standard parts compatibility for furniture/trigger).
Mil-Spec trigger with a clean break (easily upgraded if you wish).
Quality CMMG fit/finish; anodized receivers with matching handguard.
Holosun HS510C Red Dot and Magpul sights.
(Exact factory configuration may vary slightly by production run; everything installed on this firearm is shown in the photos.)
Cosmetic & Mechanical Condition
Metal/Finish: Excellent; only faint rubs at typical contact points (charging handle, takedown pins).
Bore/Chamber: Excellent; strong rifling, clean feed ramp.
Function: 100% with ball .45 ACP during our function checks.
Round Count: Low; visually consistent with limited use.
Included

6 magazines.

Brief History of the CMMG MkG/Banshee in .45 ACP
CMMG first brought .45 ACP to the AR platform in a practical way with the MkG “Guard" series, introducing the Radial Delayed Blowback design to tame the heavy reciprocating mass common to .45 straight-blowback builds. The system uses precisely angled bolt lugs to delay opening, allowing a lighter bolt/carrier and smoother recoil impulse. The Banshee branding later became CMMG’s compact line—shorter barrels, lightweight handguards, and pistol (or SBR) configurations—while retaining the same Glock-mag compatibility and RDB mechanics that made the Guard so shootable. The MkG 100 represents the straightforward, no-frills configuration that accepts upgrades like any AR, while delivering the reliable big-bore performance .45 ACP fans want.
Specifications (typical for MkG 100 .45 ACP)
Caliber: .45 ACP
Operation: Radial Delayed Blowback
Magazine: Glock 21/30 pattern
Barrel: Factory pistol-length, threaded .578x28
Handguard: Free-float M-LOK
Sights/Optic: Holosun HS510C Red Dot and Magpul sights.
Finish: Hardcoat anodized
Why Buy This One?
If you want .45 ACP in an AR-pattern without the harsh blowback feel, the CMMG RDB design is the gold standard. Add Glock-mag convenience, a compact Banshee format, and excellent, low-use condition, and you’ve got a reliable, soft-shooting big-bore pistol that’s easy to feed, accessorize, and enjoy.

Brief History of the CMMG MkG/Banshee in .45 ACP
CMMG first brought .45 ACP to the AR platform in a practical way with the MkG “Guard" series, introducing the Radial Delayed Blowback design to tame the heavy reciprocating mass common to .45 straight-blowback builds. The system uses precisely angled bolt lugs to delay opening, allowing a lighter bolt/carrier and smoother recoil impulse. The Banshee branding later became CMMG’s compact line—shorter barrels, lightweight handguards, and pistol (or SBR) configurations—while retaining the same Glock-mag compatibility and RDB mechanics that made the Guard so shootable. The MkG 100 represents the straightforward, no-frills configuration that accepts upgrades like any AR, while delivering the reliable big-bore performance .45 ACP fans want.

Why Buy This One?
If you want .45 ACP in an AR-pattern without the harsh blowback feel, the CMMG RDB design is the gold standard. Add Glock-mag convenience, a compact Banshee format, and excellent, low-use condition, and you’ve got a reliable, soft-shooting big-bore pistol that’s easy to feed, accessorize, and enjoy.

Item Overview
CMMG Banshee MkG 100 in .45 ACP. This is CMMG’s Glock-magazine variant built around their Radial Delayed Blowback (RDB) system, giving you soft recoil, reliable feeding with .45 ACP, and a lighter overall carrier group compared to straight blowback .45 builds. This example is clean, well-cared-for, and shows minimal handling wear. Bore is bright; crown is sharp; controls are crisp. Low round count—just range function checks and a couple casual trips (no classes/abuse).
Notable Features

Free-float M-LOK handguard for accessories (light, sling QD, hand stop, etc.).
Last-round bolt hold open tuned for Glock mags.
AR-pattern controls (familiar manual of arms, standard parts compatibility for furniture/trigger).
Mil-Spec trigger with a clean break (easily upgraded if you wish).
Quality CMMG fit/finish; anodized receivers with matching handguard.
Holosun HS510C Red Dot and Magpul sights.
(Exact factory configuration may vary slightly by production run; everything installed on this firearm is shown in the photos.)

Bore/Chamber: Excellent; strong rifling, clean feed ramp.
Function: 100% with ball .45 ACP during our function checks.
