A little side project we have been working on has finally begun to come together. A match grade 300 Fireball caliber AR15 carbine.
The barrel was made from a match grade stainless blank, the same as we use on any of our high end, long range rifles. It is 9" long with a heavy profile for accuracy and balance.
The pistol length gas system is coupled to a JP Ent adjustable lo-pro gas block which will allow the gun to cycle reliably with both supersonic and subsonic loads.
300 Fireball vs .223
Colt M4 upper, 10.5" 1:8 stainless match barrel with target crown, JP adjustable gas block on pistol length gas system and JP midlength modular forend.
We can also supply complete lower receivers as in the picture.
The 300 Fireball catridge (more commonly known as the 300 Whisper) is a true multi purpose case. It can push a 125gr bullet to 2200 fps making it the ballistic equal to the ubiquitous 7.62x39. Yet it can also run subsonic with bullet weights from 150gr to 240gr.
The difference from the Russian round is that the 300 Fireball will feed reliably through an AR platform without the need for modifications to the bolt or magazine. 7.62x39 AR's also tend to crack bolts regularily. So the 300 Fireball is a better choice for those looking for .30 caliber punch from an AR15.
Update July 2010: We just finished this sick 300 Fireball. It has a 9.5" heavy 1:8 match barrel under a Daniel Defence 10" Lite Rail. The gas system is pistol length and features a custom super lo-pro adjustable gas block to fit under the slim DD rail. The stock is a short Socom unit.
We have virgin Remington 221 Fireball brass and Redding 300 Fireball reloading dies currently available (Oct 2010).
These dies use a tapered sizing button to allow 221 Fireball brass to be easily necked up in a single step.
