BSF CARBON FIBER 9MM AR-15 BARRELS

Lightweight Match-Quality Barrel for Your 9MM Pistol-Caliber AR-15

BSF Barrels builds their 9mm Luger AR-15 carbon fiber barrels with the same care that goes into a top-quality match barrel to ensure that you’ll achieve the best possible accuracy from your AR pistol, SBR, or carbine. All BSF barrels are turned from ordnance-grade 416R stainless steel, then given a roll-wrapped, tensioned, carbon fiber sleeve. The sleeve keeps weight down while providing excellent rigidity, plus enhanced cooling.

BSF uses this sleeve method on their 9mm Luger AR-15 barrels rather than simple carbon fiber wrapping because they believe wrapping traps heat and is prone to delamination. Further, BSF uses a special carbon fiber that expands at the same rate as 416R, and holes drilled into the jacket allow air to circulate around the barrel and vent heat quickly. Less heat distortion means far less risk of accuracy fade as your 9mm chambered AR-15’s barrel heats up.

BSF CARBON FIBER 9MM AR-15 BARREL SPECIFICATIONS

From the manufacturer: After turning down the barrel, we jacket a 416R Stainless steel match barrel in a roll-wrapped carbon fiber sleeve and load it under tension.  We use this jacketing method rather than wrapping the barrel in carbon fiber because this method of wrapping has been proven to trap heat and cause delamination.  The carbon fiber we use is specially designed to move at the same expansion rate as 416R stainless steel. We machine slots into the carbon fiber allowing air to move around the barrel and vent heat quicker without any delamination issues.  Using the Carbon Fiber this way keeps the rifling straighter the warmer the barrel gets because it’s under tension. This allows us to maintain superior stiffness and strength while keeping the barrel extremely lightweight.

ELFTMANN TACTICAL AR-9 MATCH TRIGGER

ELFTMANN TACTICAL AR-9 MATCH TRIGGER

The guys over at 308AR.com like Elftmann Tactical triggers in the 308AR/AR-10 platforms and that’s a pretty substantial endorsement as they can be quite picky. For me I like the idea of a purpose built trigger specifically for pistol caliber carbines.Pistol caliber AR-15’s like AR-9 and AR-45 operate on a blow-back design which can be tough on lower receivers, trigger pins and of course triggers.I don’t hands on yet but I will own one of these triggers soon.

Elftmann Tactical AR-9 Match Trigger

The ELF AR-9 Drop-In Match Trigger has been built for performance. Specifically developed for 9mm and .45 PCC platforms, after tens of thousands of rounds of testing in all platforms, the boss has decided this is the best trigger we have ever produced and does it all in every AR platform. It has a u-shaped captured disconnector that forces a positive hold on the hammer and also has a “pad” that matches up to an extension on the hammer. The pad is directly in line with the rear trigger pin so when the hammer is stopped by those matching surfaces it effectively eliminates trigger slap from the hammer hitting the disconnector and greatly enhances the feel of the  trigger during live fire. Absolutely compatible with the Sig MPX!

All our performance series triggers utilize aerospace grade sealed bearings, making for an incredibly smooth and fast trigger pull. Pull weight is so easy to adjust it can be done in seconds without removing the trigger from your lower receiver. A second-to-none drop-in trigger system that is strong and light, made of wire EDM machined, hardened A2 tool steel and lightweight aircraft grade aluminum. Installation can be done in minutes using your AR’s original hammer and trigger pins. The match trigger may be ordered with a curved or straight shoe.

The amazingly short take-up, glass-rod crisp break and next to zero over travel can be compared to the finest custom 1911 triggers. Adjustability puts you in charge based on your current use. If you are looking for the finest adjustable trigger for your AR-9 / AR-45 platform, this is the trigger system for you.
