Talon Arms is bringing in a "build your own" kit next week.
It will consist of a complete M4 type upper, lower parts kit, adj stock and a mag for $550. Pick up a lower for $120 or so and you can have a complete rifle for $670 plus tax.
The upper is a CMMG 1/9 16" M4 profile with the CMMG WASP coating. A 16" 1/9 HBAR and a 16" 1/7 Bull Barrel is also available by request.
Of course, other options are available for an additional cost.
