Borden Accuracy introduces New Action for PRS and the 6 BR family of Cartridges


Borden Short Action receiver for 6 BR and Special Accurate MAG magazines

The new action from Borden Accuracy (Borden Super Short 6) features a Rem 700 short action compatible footprint with a shortened magazine well and shortened port set up specifically to reliably feed 6 BR, 6 Dasher, 6 BRA, 22 BR cartridges.  development work will be done to also do 223 and the PPC family.  The bolt has modified Borden bumps to aid in cycling in the dirty environment.  the rear end of the bolt is fitted to less than .002 diametral clearance with the action body bore to ensure locking lug lockup to result in superior accuracy and precision.  the remainder of the bolt is relieved to .006 inch diametral clearance.  the pictured action shows our standard bolt handle and tear drop knob.  production models will feature a handle that is threaded on the end so individuals can use their preferred knobs.  I have been one of the individuals that developed the bolt timing and neutral handoff with the trigger for competition shooting to minimize rifle upset in the bags when closing the bolt.  These actions will be available with either the neutral timed handoff or with about .03 to .035 inch cock on close.  The cock on close option has much easier bolt lift that seems to be favored by PRS competitors. For now the bolts will have spiral flutes but future versions will have diamond flutes as an option.  the rails are 20 MOA aluminum picatinny spec rails that extend three notches beyond the front of the action.  rails are secured to the action with 4 8×40 screws in holes that were milled and thread milled (no taps are used) and with 2 interference fit 1/8 inch dowel pins. The actions also feature a dual blind pinned hardened and ground stainless steel 1/4 inch thick recoil lug. The standard finish is beadblasted stainless for action body, and shroud.  Bolt is ground finish hardened chrome moly and the rail is beadblasted aluminum.  PVD treatment of bolt or bolt, shroud, bolt stop, action and rail available.  we are also pursuing possibly offering salt bath nitride of the bolts and shrouds. A ground and polished finish will also be available for action body, polished aluminum for rail and polished stainless for shroud.

Borden Accuracy -Borden Rifles Sales Information

We have recently found that there has been some confusion about how Borden actions can be ordered.  We have a full Retail and Wholesale program here at Borden Accuracy and we welcome individual and gunsmith/dealer orders.  For a gunsmith/dealer pricelist please email us a copy of your FFL and we will email you a confidential dealer price list.

Policy Change for using B&A triggers

Effective immediately, any action order that will be using a B&A trigger will need to send the B&A trigger here for test fitting and timing.  We have been making 2 frames for the BR series of actions (BR, BRM, BRL, BRMXD, BRMMF, BRLXD, B).  One would work with Jewell and one would work with B&A. That currently does not seem to work satisfactorily as the B&A triggers we have here now time almost same as Jewell in Jewell frame.


Borden Accuracy will be using trigger Tech Triggers

We are pleased to announce that we have thoroughly tested the Rem 700 Special Trigger from trigger-Tech and we are very impressed with the performance.  The triggers are clean, crisp pull.  They do not use a conventional sliding sear but have a rolling element in them.  We are offering these on our barreled action and action orders effective immediately.  One of the advantages of the trigger is that lots of thought went into its design and they TIME with the cocking piece pick up point the same as a Timney Calvin Elite or recent Jewell trigger.  trigger tech trigger

New Titanium Action Models

Our Titanium actions have become a homerun!  Based on the experience so far we are now accepting orders for Mountaineer, Rimrock HBR, Rimrock B and Rimrock BRM actions made in Titanium with standard chrome moly bolt, aluminum shroud and full PVD treatment!

The Ridgeline, Alpine Magnum and Timberline Magnum are pictured here for illustration.

Effective 3/21/18 we are no longer accepting orders for Titanium actions.

Internal Hook Extractor

internal hook extractor

I had previously shared a picture of the Internal Hook extractor installed in one of our coned single shot bolts that we use for the bottom eject Rimrock Benchrest actions.  The above picture is of the internal hook extractor installed in a Borden Timberline Magnum bolt. We are now offering that extractor on bolts that have the repeater nose in 308 and magnum bolt faces.  the extractor does not require any machining of slots in the outside surface of the bolt.  The extractor becomes of better option for those not wanting the Sako style extractor as it keeps ejection angle low and also minimizes the machining of the outside surfaces of the bolt body.

Alpine, Timberline, Ridgeline, Rimrock SSR, Rimrock LSR, Mountaineer models can all be ordered with the internal hook extractor for 308 and magnum bolt faces effective immediately.

Introducing The Borden Rimrock BRLXD and the Borden Ridgeline actions

The Rimrock BRLXD



BRLXD Right2016 has been an exciting year of development at Borden Rifles.  The introduction of the Borden Rimrock BRMXD action in January was a success and the demand for that action also created a demand for a longer version of the larger diameter action.  We are now producing the Rimrock BRLXD version of our BRL action.  It is 1.470 in diameter. It is available with 30-06 and standard magnum boltfaces.  It is available RBRP; RBLP, RBLPRE (for 284 and 30-06 length cartridges); RBLPBE (for up to 284 Win length cases).  We are also offering the LH versions of the same combos.

Borden Ridgeline

Alpine Ridgline Timberline

Getting the right fit in an action for mid length cartridges has been a challenge for years. Many cartridges like the 257 Roberts, 6.5×55 Mauser, 6MM Remington, 284 Win, 6.5×284 Win and the WSM and RSAUM cartridges have been put in the standard short action which restricts overall length of the cartridge and effects its efficiency. Those same cartridges when done in standard long action result in excess space in the magazine well. For that reason we have introduced the Ridgeline series of actions which feature an opening of 3.2 inches in the magazine box. These images show the three lengths of action: Alpine Magnum, Ridgeline and Timberline Magnum. McMillan will be inletting stock patterns that accept either Short or Long Remington actions for the Borden Ridgeline.

The Ridgeline is offered as repeater or Single shot and can be bought as a Titanium version as well.  We have “Standard” mag boxes as well as WSM/RSAUM mag boxes available for them. Also, the Obendorf style drop floorplate trigger guard systems are expected to be here soon.

New Rimrock BRM Multi Flat action-BRMMF


We are taking orders for the New Rimrock BRMMF action.  Its is round on bottom (radius .735 inches) and it is 1.4 inches across flats.  The RBRP version with screw on bottom lug weighs 40 1/2 ounces.  It is available RBRP, RBLP, RBLPRE, RBLPBE, LBLP, LBRP, LBRPLE, LBRPBE.  Action body is 416 Stainless hardened to 40 to 41 Rc, teh bolt body is 4140 chrome moly hardened to 43 to 44 Rc.  The bolt shroud, bolt stop and bolt handle are all stainless steel.  the trigger hanger is aluminum. It si available 308 boltface, magnum boltface and the bottom eject also offers a PPC boltface.  The stand ejection uses 308 boltface for PPC.

non dual port actions are $1325 plus $75 for bolt on lug. Dual port actions are $1400 plus $75 for bolt on lug.  We will have Dovetail bases and pic rails available soon.

Borden Alpine Magnum Titanium Action

Here are some pictures of the Borden Alpine Magnum Ti action finished with the exception of the PVD treatment. The unit as shown here weighs 19.36 ounces.

After considerable discussion with three gunsmiths today I have somewhat softened my position on selling them without PVD treatment. The action cycles nicely but it does not feel the same as 40Rc EDM cut 416SS. I am finding that is not important to everyone. So, I will offer them 3 ways. Here are the prices (taking into consideration the current cost of Grade 5 Ti hardened):
Prices are for the Ti action with chrome moly bolt with deep spiral flutes, SS handle; SS bolt stop, dual pinned SS recoil lug and fluted aluminum shroud.

Short action with no PVD-$1600.00
Long action with No PVD-$1650.00
Short action with PVD treated bolt-$1680.00
Long action with PVD treated bolt-$1730.00
Short action PVD treated action body, shroud,bolt stop, recoil lug,bolt body–$1900.00
prices are for the Ti action with chrome moly bolt with deep spiral flutes, SS handle; SS bolt stop, dual pinned SS recoil lug and fluted aluminum shroud.
