The CMC BBL FOR G17 FLT BRZ Made a Bold First Impression
The CMC BBL FOR G17 FLT BRZ promises enhanced accuracy and a touch of custom style to the ubiquitous Glock 17. From CMC Triggers, a name synonymous with quality aftermarket firearm components, this barrel boasts features like a bronze TiCN finish, fluted design, and a Hexagonal Boron Nitride (HBN) treated bore and chamber. My journey to this particular barrel began with a nagging desire to squeeze more precision out of my Gen 3 G17, a trusty sidearm that had seen its fair share of range time.
I had been experiencing inconsistent groupings beyond 15 yards, a problem I attributed to the stock barrel’s limitations. The allure of a drop-in replacement promising improved lockup and tighter tolerances was strong. Unboxing the CMC BBL FOR G17 FLT BRZ revealed a beautifully machined piece. The bronze finish was even richer in person than online photos suggested, and the fluting added a distinct aesthetic appeal.
The weight felt slightly heavier than the factory barrel, which I immediately perceived as a positive sign of robust construction. I was torn between this and a ZEV Technologies barrel and a Faxon Firearms barrel. Ultimately, the CMC barrel’s combination of attractive finish, fluting, and the promise of superior bore treatment tipped the scales. Initial impressions were decidedly positive; I was eager to see if its performance matched its impressive appearance.
Real-World Testing: Putting CMC BBL FOR G17 FLT BRZ to the Test
First Use Experience
My first test of the CMC BBL FOR G17 FLT BRZ took place at my local outdoor shooting range. I brought along a variety of 9mm ammunition, ranging from standard 115-grain FMJ to 124-grain +P hollow points, to gauge its performance across different loads. The weather was mild and dry, providing ideal conditions for accurate shooting. Installation was a breeze, a true drop-in fit that required no gunsmithing.
I immediately noticed a difference in recoil impulse; it felt slightly reduced and more controlled, likely due to the tighter lockup. Accuracy was noticeably improved; my groupings at 15 yards tightened from about 4 inches with the stock barrel to around 2.5 inches with the CMC barrel. There were no immediate issues or malfunctions after the first 100 rounds, a promising start.
Extended Use & Reliability
After several months of consistent use, the CMC BBL FOR G17 FLT BRZ continues to impress. The bronze TiCN finish has proven surprisingly durable, showing no signs of wear despite frequent cleaning and holster use. Regular cleaning is straightforward; a standard bore brush and solvent easily remove any fouling. Compared to my previous experiences with other aftermarket barrels, the CMC barrel has outperformed in terms of both accuracy and ease of maintenance.
I have now put over 1000 rounds through this barrel, and it has remained consistently reliable. I’ve experienced no malfunctions attributable to the barrel itself. The HBN bore treatment seems to genuinely reduce friction, contributing to smoother cycling and easier cleaning.
