This TacFire AR-15 build kit comes with everything you need except a lower receiver to assemble your rifle. Whether this is your first build and don’t know where to start or your tenth and you just want something that is quick and easy to build without picking every single part, this kit is for you. From the Mil-Spec lower parts kit to the 16” M4 profile barrel chambered in 5.56 NATO, every part is built to last, making your new AR great for training at the range. The forged barrel features a 1:8 twist rate and is threaded 1/2x28 for attaching the included A2 flash hider. The barrel and carbine length gas system and block are covered by the 15” Slim Line M-LOK handguard. This free float handguard is machined from aluminum and offers plenty of QD slots for attaching rail segments or other accessories. Check out the TacFire AR-15 build kit for a one stop shop experience with everything you need to build a rifle for the range.

The TacFire build kit uses all Mil-Spec components, so you can easily upgrade parts in the future if you so choose. The carbine length receiver extension uses a standard recoil spring and 3 ounce buffer weight to compliment the gas system and provide exceptional reliability with 55 grain ammunition. The 6-position adjustable stock allows you to quickly fix the length of pull to your preferred length and features a rubber butt pad.

TacFire build kits are extremely easy and fun to build. They come with all the Mil-Spec components you need with the added benefit of a free float handguard instead of a crappy plastic two-piece handguard. All you need is an Anderson Manufacturing lower receiver and you can build a sub 500 dollar AR-15 that will do everything you need it to.

Primary Arms & This Kit Are Excellent

by -

I ordered this kit on Easter Sunday. Primary Arms shipped it the following day and I received it on Friday. Thank you for the great service.
<br>This kit is very well made. I built it on an Anderson lower. All of the parts, pins, etc. fit well and were simple to install. The trigger has a nice, clean break and short reset; It’s much better than I expected. Actually, the gun itself performed much better than I expected.
<br>I sighted it in at 50 yards with a Crimson Trace CTS-1000. After it was zeroed, it was hitting super tight groups. I didn’t measure, but they were damn near touching each other every time. 100 yards was really good also; I’d say 1/2” or so consistently.
<br>Overall, great experience. I will definitely be buying from Primary Arms again.
