Proto Tactical has been manufacturing large caliber AR
style rifles for years... we offer "DPMS" style receiver assemblies and
complete .308 rifles - models include a lightweight 16.5" Barreled
Carbine and a 20" Long Range Precision Rifle..
Both upper and lower receivers are machined in-house to control many
of the close tolerances that other manufacturers don’t hold. Concentricity
between barrel bolt and upper receiver is less than .002”. Each rifle receiver
is hand fit during assembly and is fully guaranteed.
rifles are tested for proper function with the desired optics to ensure MOA or
better accuracy (1” groups at 100 yards) before it is delivered.
