*Only Compatible with 1.45″ OD Solvent Trap Tube Kits*

The AD M34 Muzzle Extension (M34x1.25 TPI), identical to the ADV1 Muzzle Extension in design, but with a muzzle thread pitch that adapts to our 1.45″ OD Aluminum and Titanium Solvent Trap Tube Kits. The thread pitch of M34x1.25 is made specifically for the 1.45″ OD Kits.

This highly demanded attachment weighs in at 3.8oz allowing browning type action firearms to slide back properly. Most pistols with a browning type action (Glock, Sig Sauer, HK, etc.) will require this muzzle extension to allow your firearm slide to rack properly and proceed with bore cleaning processes. Glock Guide Rods tend to hit the bottom of solvent traps which blocks the slide from opening, this Muzzle Extension solves this problem.

If you are looking for a Muzzle Extension solution a 1.1875-24 TPI, you should check out our ADV1 and ADV2 Muzzle Extension Devices.

The AD M34 Muzzle Extension (M34x1.25 TPI) is identical to the ADV1 Muzzle Extension Device in build and design, but differs in Thread Pitch. The AD M34 Muzzle Extension Device has a unique Thread Pitch of M34x1.25, which ONLY matches the thread pitch of the 1.45″ OD Solvent Trap Tube Kits.

This highly demanded attachment weighs in at a little over 3.8oz. For those that want to purchase one of our 1.45″ Outer Diameter Titanium Tube or Aluminum Tube and Stainless Steel Cup Kits and the AD M34 Extension Device, our recommendation of a combined purchase comes only from a “Firearm Cleaning” point of view: Muzzle Extension Devices provide extra length which helps in the solvent trapping process to different degrees, depending on the type, model and/or brand of pistol it is being used on.

For example, Glock owners love the AD M34 Muzzle Extension because with most threaded barrel configurations, the Glock Guide Rod extends and is blocked by the base of an installed solvent trap. When the guide rod is blocked when attempting to ‘rack’ the slide, the entire process is halted. In every Armory Den test, the AD M34 Muzzle Extension has provided enough additional length to allow the slide to rack completely, allowing solvent, barrel snakes, barrel swabs, and other cleaning tools to be fed into the ejection area for bore cleaning

Those interested in purchasing a Muzzle Extension Device from Armory Den, must agree and read the notice prior to purchasing Muzzle Devices from our websites. Other customers may also purchase muzzle devices for aesthetics and/or to adapt to items that were purchased elsewhere.

Important Notice:

We sell muzzle devices as an accessory, and they can have multiple purposes, we do not recommend or direct how our customers use them. It is the customers responsibility to ensure they read our Legal Den area, and if the muzzle devices are used more than an aesthetic piece or as a solvent trap accessory for increasing a cleaning kits length or adding an adapter between the barrel and muzzle accessory, that customers operate within the rules and regulations of the NFA.

Those interested in purchasing a Muzzle Extension Device from Armory Den, must agree and read the notice prior to purchasing Muzzle Devices from our websites. Customers may also purchase muzzle devices for aesthetics and/or to adapt to items that were purchased elsewhere. Other customers may purchase these muzzle devices due to the additional thread patterns available on these devices, serving as a "barrel extension" on popular browning style pistols, such as Glock, so the guide rod clears the base of the solvent trap.

Armory Den accepts no responsibility for how our muzzle devices are used and it is the customers responsibility to pay the $200 tax stamp and get an approved BATF Form 1 if applicable. Please see our Terms & Conditions and ATF Legal Den page for more information.

MUZZLE DEVICE NOTICE

Those interested in purchasing Booster and/or Trilug muzzle devices from Armoryden.com, must read and agree to this notice. Many of our customers purchase these muzzle devices to adapt to items that were purchased elsewhere, while other Armory Den customers purchase them due to the additional thread patterns available on these devices and acting as a “barrel extension” on some popular browning style pistols, such as Glock, so the guide rod clears the base of the solvent trap.

Our current offering of thread mounts that are included with our solvent trap kits and also sold individually are 1/2×28″ and 5/8×24″. Many of our boosters are offered with additional thread patterns, such as .578×24″ and 9/16×28″, allowing our solvent trap cleaning systems to adapt to barrels that require additional thread patterns, such as most .45 ACP pistols. Our AD Trinity  9mm 3-lug barrel Trilug Muzzle Device allows barrels with this unique 3-lug setup to adapt Armory Den’s solvent trap cleaning systems.

As mentioned above, some browning style action guns, such as Glocks, need a booster for our solvent traps to work properly because of the guide rod that protrudes from the front of these pistols when the slide is charged or put into battery. The bottom of the solvent trap cleaning system blocks the guide rod from moving out completely, which in turn blocks the firearm slide from moving backwards into an open and locked position.

Therefore, the booster acts as an extension so the slide can fully “rack”, allowing barrel snakes, cleaning rods and solvents the necessary room fit through the ejection port area and into the barrel for cleaning

All of our boosters and Trilugs ship separately at Armory Den’s cost and with their own tracking numbers, so there is no confusion as to  Armory Den’s view or position on the recommended use of its boosters and trilug muzzle devices.  By selecting “Yes, I Agree” customers are stating that they understand everything detailed above and agree that it is their responsibility to purchase these independently sold items only to be used legally and on legal devices.
