If the back part of the barrel with the O-ring on it popped off like mine did, glue it back on to the barrel. Get out your pennies and check your compression. Two pennies gave me full compression, but the blaster wouldn't prime, so I had to go back down to one. If the Strikefire is anything like Mavericks, the number of pennies you need will change from blaster to blaster, so make sure you check what works best for you.
I saw a 5-10' range increase by performing these mods, which is normal for an AR removal. A complementary video tutorial for this guide should be up soon. Feel free to ask questions.
