I have a lightly customized Remington 700 LTR in a Spuhr SICS chassis and I love it. Very comfortable and steady and it feels like really good quality. It’s still a factory Remington barrel so I don’t want to call it a hammer by this forum’s standards, but it’s one of the best shooting rifles I’ve played with. I want to build a custom (or maybe even a couple) rifle on a custom action and am looking at the normal cast of characters - Lone Peak Fuzion, Impact 737, Defiance Deviant Tactical, etc. I haven’t decided for sure what I’m going to use yet, but as of lately I’m kind of on a Deviant kick. Anyhow, I want to use another Spuhr SICS chassis, along with a Trigger Tech Diamond trigger. I want an action cut for AW mags whether I use them or stick with AICS. Since this will be the first rifle I’m assembling, I want to minimize futzing around too much to make things work. So my question is, has anyone used a Defiance Deviant Tactical action with a Trigger Tech Diamond trigger in a SICS chassis? Was it pretty much plug and play or did it require tweaking? Did it work well with AW mags as is (I know the AW cut is an option on the Deviant but I’ll be getting that option if I go that route) or did it require extensive modifications to make it work? Any tips, hints or suggestions from anyone that has used this action/ chassis/ trigger combo? Any reason to flat out abandon this combo and use the Lone Peak Fuzion or Impact 737, other than brand preference? Thanks in advance for your input.
 
Ok,

That action should drop into the Spuhr chassis just fine. Adam did say to use AW mags you need the gunsmith installed mag catch.


or just use AICS mags.

Thank you! If for whatever reason I wanted to try AW mags but then want to go back to AICS mags, it looks like I would be able to do so correct? Just reinstall the original mag catch? Thanks again, I’m loving my purchases from April as I was passing by the Wyoming store. I’m so glad I was able to stop in person.

Obviously I can't guarantee anything, but I use the standard latch with my 737r and my standard AW mags work for 6.5 creed after some feed lip tuning and reliability has been great.

Hey,

The Wyoming guys are great. I try to get up there as much as I can. As far as the mag thing I would have to double check with Adam, but it seems as though you could just switch back to the original catch. I will verify.
