Thank you for sticking with us — the latest from M*CARBO
It's been a while, and we've spent that time sharpening the parts of our business that matter most to you: customer care, support workflows, and the resources that make buying, installing, and enjoying M*CARBO parts simpler and more reliable. At the same time, we've been quietly developing hardware tuned for the newest generation of platforms hitting the market. Below you'll find our most recent releases, organized by brand, with short notes on what each item aims to do for the shooter.
Practical upgrades—whether for daily carry, defensive use, or hard range hours—are judged by two things: do they solve a real problem, and do they maintain reliability under use. We focused on those criteria when choosing what to develop and release. Read on for short, functional descriptions of what's new and why you might consider each item.
KEL-TEC (SUB-2000 Family)
Bolt Tube Cover (Gen 3) — A soft cheek pad that improves comfort and encourages a repeatable cheek weld on SUB-2000 Gen 3 platforms. Simple fitment, immediate ergonomic payoff for optic or iron-sight setups.
SUB-2000 10mm Muzzle Brake — CNC-machined to reduce muzzle rise and felt recoil on heavier 10mm loads. If you run full-power 10mm through a SUB platform, this brake is a clear control upgrade to speed follow-up shots.
GEN3 5.7 Grip Pin Upgrade Kit & GEN3 Grip Pin Upgrade Kit — Reinforced steel pins and hardware to replace weaker factory parts. Drop-in durability improvements at common stress points — straightforward, inexpensive insurance for high-use guns.
Ruger
PC Carbine / LC-10 10mm Muzzle Brake — A tune specifically for the Ruger PC Carbine 10mm that flattens the recoil impulse and reduces muzzle rise. Results: cleaner follow-ups and better controllability for defensive or range use.
Smith & Wesson
FPC-Max — Optic Mount & Charging Handle Upgrade (9mm & 10mm) — A combo kit pairing a precision CNC optic mount (co-witness-capable) with a stout aluminum charging handle designed to let you confidently rack with one finger and avoid muzzle-to-nose contact. Offered in dedicated 9mm and 10mm variants.
M&P FPC Muzzle Brake (10mm Only) — Compact, purpose-built recoil control for the FPC 10mm. A small change to the muzzle that yields measurable improvements in muzzle flip and follow-up speed under heavy 10mm loads.
SIG / Glock & Misc
P365 XL Compensated Slide with Ported Barrel (3.1") — Premium 17-4 PH slide with a ported 3.1" barrel, dual top and side ports, and an RMSC optic cut. Reduced reciprocating mass and a cleaner recoil impulse make this a compelling option for P365/X users who want faster, more consistent follow-ups. Built in the USA and backed by our lifetime guarantee.
Sig P365 Precision Steel Barrel (3.1", 416R, Black Nitride) — Match-grade 416R barrel finished in black nitride. Drop-in, +P rated, and tested across a wide range of loadings for improved accuracy and longevity versus typical factory barrels.
ProMag 50-Round 9mm Drum (Glock 17/19) — High-capacity drum for extended range sessions. As always with high-capacity magazines, test fitment and function with your specific setup before relying on it in critical use.
