SBR, BANSHEE, MkG, .45 ACP, 5"
Chambered in what is arguably the most patriotic pistol caliber available, this .45 ACP BANSHEE™ SBR is one of the most compact BANSHEE SBRs CMMG® offers. With a barrel length of 5”, this SBR is the right size to go anywhere.
Available in a range of cerakote finishes, the BANSHEE series represents the most innovative AR pistols and SBRs available today. From the quick deploying RIPSTOCK®, to the stylized receivers and EML™ handguards, every BANSHEE is tailor-made to be the personal defense weapon you can always depend on. New EML4 handguards feature M-LOK® slots at 3, 6, & 9 o’clock positions and a full length picatinny top rail for accessories as well as an integrated handstop.
MkG Radial Delayed Blowback
Since making its debut on the original .45 ACP MkG platform in 2017, Radial Delayed Blowback has revolutionized pistol caliber ARs across the entire CMMG lineup. As a result of meticulous engineering, Radial Delayed Blowback not only addressed some operational concerns with a traditional straight blowback system, but it also delivered pistol caliber carbines and personal-defense weapons with softer recoil impulses and lighter weight bolt carrier groups and buffer systems than straight blowback systems could deliver. Check out our CMMG Resources article & video to learn more about what sets Radial Delayed Blowback apart.
**All NFA rules apply** All BANSHEE NFA SBRs (short barrel rifles) require additional ATF paperwork & processing time. See linked CMMG Resource article for more information.
