Repinned a trifecta for Silencerco SPECWAR 556KReview by Vince
Very impressed with staff. Very professional in helping me throughout the process and keeping me informed. My Noveske N4 looks awesome and can't wait to attach my SPECWAR 556K to it!!! Would highly recommend Ranier Arms! (Posted on 7/30/2016)
Superb, professional jobReview by Daniel
Ordered the pin weld service to pin a Silencerco Trifecta to a BCM 14.5" barrel. Was worried the small space to work with on the trifecta, however, Rainier Arms did an outstanding job. Flawless clean appearance, looks exactly like the picture. Fast turnaround and excellent customer service. Even received an email when they got my parts. I would highly recommend the gunsmiths at Rainier Arms for your gun smithing needs. Proffessional! (Posted on 6/4/2015)
