Unassembled Rifle Kit with Free-Float Handguard

Build a complete AR-15 that can do it all at an excellent price point with Tacfire. This kit ships to your door unassembled, with everything you need, less your choice in lower receiver to make a range-ready rifle. With a reliable carbine-length gas system and a free-floated barrel, this kit will come together into a gun that’s ready to run.

Be sure to snag a barrel nut wrench for ultra-secure handguard installation!

The Do-Everything, High-Value Rifle Kit

Once assembled, the free-floating barrel has great accuracy potential. With a 1:7 twist rate, your new rifle will stabilize everything from 55 grain range ammo to 69 plus grain match projectiles. And the free-floating handguard will keep your groups tighter than a standard M4 style upper. With the milspec fire control group, you’ll get positive ignition with steel cased ammo, with a standard 5 to 6 pound trigger pull.

The bottom line on this kit? It has everything you need for a reliable AR-15 build, with features you might pay out the nose for with an off-the-shelf rifle. With what you save in roll marks or brand names, pick up ammo, magazines, a red dot sight, or any other accessories you need. Plus, it’s a perfect companion to an 80% receiver.

Tac fire is garbage

I recently bought a handguard from Classic firearms. It would be a nice handguard of not for the deep scratches all down the side. No damage to the packaging. It was shipped that way. It's been a month now. They asked for order number and reciept.i sent it and haven't heard anything else.i paid insurance to protect my shipment. Classic sent me to tacfire. Tacfire hasn't done a thing after responding 3 weeks later. At3 products are always good, but stay away from anything with the name tacfire.

Economic build

I’m a novice/ intermediate builder, only about 5 AR’s so far. This was a fun build, it’s a cheap kit and I used a cheap lower too. The action was a bit gritty, I sanded and lubed it up, now it’s smooth. The weapon didn’t cycle correctly because the gas tube hole didn’t line up with the dimple on the opposite side of the barrel. I emailed AT3 they got back to me right away. Their suggestion was to gap the gas block about a credit card width away from the barrel shoulder. That adjustment got me closer, a credit card is about .030” my final gap was .025” now it cycles and functions properly. Also, the BCG was sticky, I soaked the whole thing in break-free CLP, it did the trick, it functions smoothly. I hope this helps the next person.

Surprised it doesn’t come with any paper instructions but was able to figure it all out through the videos on AT3’s website.

SUPER products, and the best customer service, thank you AT3!
