Rainier Arms RM15 Lower Receiver Setup
Posted by rick cancino on Apr 3, 2015 in Articles, New Products | Comments Off on Rainier Arms RM15 Lower Receiver Setup
This is a short and sweet reference article for folks on the internets trying to find this info. The RM15 lower receiver is reminiscent to the Seekins Sp223 lower receiver with their captured detent spring. This gets us away from the traditional retention method of securing the spring with the buffer endplate. Just be sure you have a .050 allen wrench on hand because they are not commonly found in most generic tool kits. You will have to cut down the detent spring a few coils. Your results may vary due to spring manufacturers so test, cut, test etc until you find your solution. The setup in the following photos only needed 6 coils removed from the spring. Hope this info helps! If it does, leave us a comment below so we know to keep sharing info like...

Posted by rick cancino on Nov 20, 2014 in Articles, New Products | Comments Off on Gem State Armory, Armorers Wrench & Rainier Switch Installation
I had a hard time deciding one what to write about first, the difficulties I had installing the Rainier Arms Switch handguard, or the success I attained with Gem State Armory’s Wrench. I guess for this one I will start with the problem that introduced me to one of the best wrenches on the market! So we were putting together a 308 upper and decided to use the new Rainier Arms Switch handguard which is made by Fortis MFG. in WA. The difference is minute, the Rainier version just has an awesome angled cut in the front similar to diamondhead’s handguard, but in a lighter fashion. The Switch handguard has a lever to lock the handguard onto the proprietary barrel nut that came with the handguard. This way if you wanted to change out handguards, you can. I don’t know why you would want to change between other switch handguards, so if any of you have an idea why you would, PLEASE comment and let us know! From what I gather, they had a previous barrel nut design that required indexing vs this new design which you just torqued the nut to spec and it was good to go. Where I ran into a problem was with the new barrel nut and the bull barrel (Rainier Arms 308 UltraMatch), none of my adapters or wrenches would fit! Here you can see the standard ar10 style pinned adapter wont fit around the barrel. I contacted Gem State Armory (G.S.A.) and asked them if I had ordered the wrong adapter. Jeff, the Owner of G.S.A. contacted me to help me figure out what was going on. After corresponding back and forth is when we figured out that Fortis/Rainier changed the design and we were able to figure out the specs for a new adapter to work with the new nut and bull barrel. Final Product! Adapter fits like a glove! Here I am starting to crank it down. I completed the install with my torque wrench inserted into the 1/2″ drive port. Now that we got the problems solved of torquing down the barrel nut, now we can talk about the solution bringer! The Gem State Armory wrench is made from...
Read MoreParallax Tactical’s FFSSR Keymod Free Float Rail VS Rainier Arms Force
Posted by rick cancino on Sep 16, 2014 in Articles, New Products, Uncategorized | Comments Off on Parallax Tactical’s FFSSR Keymod Free Float Rail VS Rainier Arms Force
For my AR Pistol build I wanted a light, small handguard. Thankfully customers asked and manufacturers listened so they have been producing some fantastic solutions. Today we are going to do an over view of two handguards. Rainier Arms Force™ Free Float System 9.0 and Parallax Tactical’s PXTreme FFSSR Keymod Free Float Rail 9.2″. Both are keymod based systems which are an effective way to strip handguards of unnecessary rails that only add weight. When a user needs to attach an accessory they only need to attach a keymod rail for the desired add on. The FFSSR rail I opted for the Cerakoted Magpul FDE version, you can order them in a multitude of colors from Parallax. Since I had the Force rail already in use, it has some Noveske NSR covers on it. Technical Specs from Parallax’s website. 9.2″ OAL 6061 T6 Extrusion Type III, Class 2 Hard Anodized and Bead Blasted Finish Features our new barrel nut, 18% lighter than previous at 92g. (Noveske at 84g.) Same slot spacing to take any Magpul MOE rail accessory on the 45 degree slots. 10-32 holes on top rail to mount Sling Studs and future accessories. Included anti-rotational QD hole Includes Barrel Nut, Screws and Includes Optional Shims for spacing Installation Instructions Included Made in USA with Domestically Sourced Materials 1.52″ OD 1.35″ ID (Will not fit most supressors and KX3.) Technical Specs from Rainier Arms Length: 9″ Material: 6061 T6 Finish: Type III Hard Coat Anodized 1913 Continuous top rail Dual anti rotation tabs Keymod Modular attachment system Outer Diameter: 1.8″ Inner Diameter: 1.5″ Weight: 7.8oz with barrel nut Proprietary barrel nut included Armorer’s wrench needed for installation (not included) Outside dimensions 9.2″ Parallax on top and Rainier Arms 9″ on bottom. The FFSSR handguard mounts with 6x mounting screws whereas the RainierArms Force utilizes 8 to secure the handguard to the barrel nut. Both handguards have a QD mounting point in the rear on both sides (pictured above) Now on front end of the handguards you have a bit of a difference between the two units. The Force has another QD mounting point on both sides whereas the FFSSR was able to fit in two more keymod slots. ...
Read MoreOVERVIEW: Fortis ‘Hammer’ Charging Handle Vs Rainier Arm’s Raptor
Posted by rick cancino on Dec 18, 2013 in Articles, New Products, Uncategorized | Comments Off on OVERVIEW: Fortis ‘Hammer’ Charging Handle Vs Rainier Arm’s Raptor
“Drop the hammer” sounds quite a bit cooler than, “pull back on the op rod” (Walking Dead), so how could I resist taking a look at Fortis’s new charging handle. Fortis uses their Nickelene finish on the charging handle to increase lubricity during use. They engineered the design to transfer energy thru the release lever into the handle compared to traditional design. Mil Spec handles have a failure point if you put strain on the the release lever while Pinch-charging. There is a potential of breaking the roll pin while using the pinch-charge method. The Claw method of charging is inefficient use of your muscles and is an un-natural form. By allowing the transfer of energy thru the release lever into the handle allows you to make the most of pinch-charging without the fear of damaging your handle. Fortis Hammer next to the Rainier Raptor Back end view Manufacturer’s information: The new Fortis Hammer™ charging handle stays true to our brand. We engineer, design, & develop military grade accessories that look good and functions great. Tested and evaluated by the 3 Gun community, then put to the test by people in the military and law enforcement community. We continuously refined our design and came up with the Hammer™. So charge your rifle by dropping the Hammer™ and go! Introducing our unique finish called Nickelene™. The slick finish is smooth and gives the already durable charging handle, a lubricity not found on another other charging handles in the market today. Machined from 7075 T6 Billet aluminum The robust design as well as aggressive serrations on the latch and body support use with either shooting gloves or without Redesigned the back stop for the latch, so stress is taken off the roll pin Finished in Nickelene™: Rockwell hardness – 45C, low co-efficient of friction, excellent lubricity characteristics You can purchase the hammer from Fortis MFG’s...
