![]() Compatibility: The GP-N is meant for A2 style flash hiders with the collar/mount machined directly into the silencer body.Flat shims are required to properly mount the A2 birdcage and insure that the barrel bore lines up concentric to the suppressor bore. Unfortunately, crush washers can be a killer of suppressors. Crush washer replacement: I’m willing to bet that 99% of all A2 flash hiders on AR-15 style rifles use a crush washer to properly time the vents/porting on the barrel.The GP-N adds about five ounces and a little more than an inch in length. ![]() Length and weight: Attaching a suppressor to a muzzle device that was not designed to be a mount as its primary function will mean some additional material and space to allow the mechanism to function.Adding the Griffin Armament GP-N to the armory is about as easy at it gets.Īs with any type of firearm upgrade, there are a few trade offs for adding “universal” capabilities. Standardization: Law enforcement and other organizations have rules about weapon modifications that may prevent the use of certain muzzle devices.Availability: If you don’t already have a few stashed away in a parts bin, finding an A2 flash hider at Brownells or another parts supplier for around $10 should be easy.Cost: Suppressor muzzle devices can run as high as $150 and the attachment system (if your silencer only came with a direct thread module) can add another $200 to the overall cost.With all these excellent choices available, why should we care about a 50+ year old flash hider that was never designed to be a suppressor mount in the first place. Plus, chances are if you’ve bought a complete AR-15 rifle or upper receiver in your lifetime, it probably came equipped with an A2 birdcage flash hider.īut, technology, testing and manufacturing techniques have developed some very effective flash hiders and muzzle brakes from companies like SureFire, YHM, Dead Air, Griffin and others. Sure you may think The Beatles are outdated and annoying, but you still have a few songs tucked away on your phone for nostalgia. If muzzle devices were musicians, the A2 flash hider would be The Beatles – the most recognizable, the most popular and the most universally loved flash hiders in history. To compare the output quality between the two, I played a CD through the Apple Pro Speakers using the iMac’s built-in port, and then played the same tracks through the same iMac using the iFire to power the speakers.Ī concern for some might be how the iFire’s quality compares to the iMac’s built-in amplification.SILENCER SATURDAY #174: Griffin Armament GP-N – Long Live The Birdcage! ![]() ![]() While this is an unscientific comparison, any major changes in distortion and frequency range should have been audible. A Miles Davis CD was used for the comparison because the CD offered uncompressed audio and the selection of music offered a wide frequency range with marked changes of instrumental emphasis and volume. There was no significant difference between the iFire and the iMac’s built-in Apple Pro Speaker output. The speakers sounded identical at the same volume levels (neither louder nor quieter with one or the other) and there was no noticeable difference in audio quality using the iFire.Įxactly as it is advertised, the iFire is an ideal solution for those who want to use their Apple Pro Speakers with other Macs or iPods. This makes the iFire and Apple Pro Speakers a good alternative for college students and those on the go who have space and portability considerations. J16:17 EST #2 Connect the Apple Pro speakers to the iFire, using their own cable.J18:46 EST #1 Do you have an idea how can I adjust volume by connecting ipod via ifire to the speakers?
