Their .308 match grade carriers are the nicest I've used. Certainly plan to grab a few of these.

Attn John Hwang:
i dont know why im gettin so much negativity here on this forum from the admin UWone77 (Asswhole)..
I dont think i ever said anything even remotely offensive to anyone..
I just got on here a few days ago..
Thought this site was Associated w Rainier Arms of which ive been a loyal customer for yrs...
What better place to show of stuff i was so proud of most of which has Rainier Arms engraved on the side..
the admin AUwone77 has taken a few unprovoked shots at me and referred to me as annoying..
really pisses me off..
Since im not welcome here..
as an admin urself.. delete all my content here.. then delete my act here..
and call me up so we can talk about you buying back all my Rainier Arms shit
me and my wife have bought from you..
