In this section we've compiled a list of frequently asked questions, as well as some tricks and tips to help with the installation of our products.





Inletting our One-Piece Bottom Metal Assemblies:

Q: "what is involved in inletting your one-piece bottom metal into my factory stock?"

A: Well, that will depend on the model that you purchase, but we will describe here all of the possibilities for both the Remington and Winchester rifles.

For Winchester Post-64 long-action and short-action, which includes the push-feed models, as well as the "Classic" actions that use 3 screws to attach the trigger guard and floorplate; this is what will be involved:
     The factory hinge that is on your rifle is approximately .172" thick and is not connected to the trigger guard.  Your trigger guard is .700" wide and has two screws that attach it to the receiver.  The One-Piece Bottom Metal Assembly eliminates the middle screw and connects the trigger guard to the hinge by means of a connecting rail.  The hinge area of our One-Piece Bottom Metal Assembly and connecting rail are nominally .312" thick.  It will be necessary to inlet your existing stock profile in the front tang area and on either side of the magazine box area to that .312" depth.  Material must be taken out on the sides of the magazine box to obtain the proper fit.  While it is a pretty simple job; it will not fit without this material being removed.
     The section that is the actual trigger guard, in most cases, will not require inletting and should drop into your factory inletting.

For Winchester One-Piece Aluminum Bottom Metal Assemblies used on the the newest of Winchester's short-action and now long-action Model 70's; Our Bottom Metal will drop-in.  No need to do anything, but remove the two screws that hold the trigger guard assembly in place and swap the magazine spring over to your new bottom metal.......It's that easy. This includes the new FN Model 70's as well in both short and long-action configurations.

For Winchester Pre-64 Model 70's in all calibers; the inletting process will be nearly identical as to what was described for the Post-64 Model 70's.  Your factory trigger guard on a Pre-64 is .600" wide, as opposed to .700" wide on Post-64's.  As a result of this, we made the trigger guard .620" wide to fill the gaps in the pre-64 stock, or provide an opportunity for you to use our bottom metal in a stock that has already been finely inletted for your factory bottom metal.  Since the Pre-64 has been sought after for many years as the basis of fine custom rifles, we want to ensure that when you use our bottom metal, you'll still get to have a fine wood-to-metal fit.
For factory chamberings of 375H&H and 300H&H, you'll need to modify your existing magazine box slightly.  This will not cause you to loose magazine capacity, or sacrifice reliability in any way.  A simple notching of the rear of the magazine box will permit it to fit into our bottom metal.  For details on this procedure, please contact our toll-free number at        1-888-257-3006.

For Remington Model 700 Short and Long-Action BDL's:
Our new Drop-In Bottom Metal requires no inletting into Remington factory stocks or aftermarket stocks inletted for the factory BDL bottom metal.

After-Market Triggers and Our Assemblies

All of our new Remington bottom metal can be used with any trigger originally designed for the Remington 700, including Jewell, Shilen, Timney, and Rifle Basix triggers without modifications to the trigger or trigger guard.

Q: "Does your bottom metal have draft on the sides to aid in inletting?"

A: Our drop-in Remington bottom metal has "draft" on the sides, which is basically an angle cut made at 2deg. to help the person inletting by hand, make the installation process easier.  Our older-style Winchester bottom metal does not, but  that feature is on the newer models with inside-the-bow releases.  Since the older models do not, an option to aid in this problem is to use a sharp, fine file and create a chamfer on the bottom side of the bottom metal and trigger guard area.  By doing this; it will provide a way of getting your scribe under the profile of the guard, allowing you to remove a little material at a time, while you inlet the part into the stock.  While this is not as ideal as having draft on the part, it allowed us to keep the cost down to our customers.  Up until the introduction of our new drafted bottom metal, comparable bottom metal with draft, would cost 3-4 times our prices.   A skilled gunsmith can normally inlet our older-style bottom metal by hand in less than 2 hours with hand tools using the method described above.

Q: "How hard is it to replace my factory Winchester extractor with machined part?"

A: This is a very simple procedure outlined here on our extractor page.  It requires no special tools or gunsmithing skills of any kind.  If after reading the instructions and attempting it yourself, feel free to call our toll-free number at 1-888-257-3006 and we'll be glad to talk you through it.

Q: "How do I know if my extractor is fitted properly?"

A: Your extractor should hold your cartridge under it's lip snugly, but not so tight that it will take excessive force to fit it under the lip.  Removing the bolt from your rifle and placing an empty shell-casing under the extractor lip will let you know if the extractor is going to hold onto your particular cartridge.  If the cartridge slides in very loosely, you'll need to remove the extractor as outlined here in our instructions page and put a slight bend in it right behind the milled pocket on the underneath side.....basically, the beginning of the tail of the extractor.  Do this only slightly, until you see that you are getting a nice fit on your cartridge.  If you have too much tension, simply bend the extractor out a little, reducing the tension on the cartridge.  Again, if you have any questions, feel free to call our toll-free number at 1-888-257-3006 and we'll be glad to assist you in any way we can.


Q: "I have a 338 Winchester Magnum....What type of extractor will I need for this cartridge?"

A: First off, you have a magnum cartridge, which means you'll need a magnum extractor, but we'll also need to know whether or not you have a right-hand or left-hand rifle.  The length of our extractor is 4.45" long and is the same length regardless of whether you are using this on a 308 Winchester or a 375H&H....The only difference is the radius that is machined on the nose of the extractor to accommodate the larger or smaller case head.
Below is a chart with some of the most common calibers that will give you a good idea as to what extractor you'll need depending on the cartridge you have.  While this obviously isn't all of the cartridges our extractors will fit, it will provide a good basis so that you can determine whether you see a parent cartridge of your caliber in question......Such as, a 280 Remington would be in the same class as the 30-06 and 270.  Both of which share the same parent case.

Proper Magazine Box Fit After Installation of One-Piece Assemblies

     One problem that gets commonly overlooked when inletting for bottom metal, whether it be one-piece, or Winchesters original bottom metal; is that there's normally not enough free-play in the magazine box after the rifle is completely assembled.  A lack of free play in the magazine box will cause the mag box to be in a bind between the bottom metal and the receiver.  When this happens, your rifle, regardless of how well it's bedded, will not be stable under recoil, and a teeter-totter effect will occur, causing groups to be very erratic.
Below is the simplest method for eliminating that problem:

  • Inlet your stock for the new bottom metal
  • Glass bed your rifle on the top, as well as the bottom.
  • Reassemble the rifle, less the mag spring and follower.
  • Do not torque actions screws all the way down yet.
  • Open up the floorplate and see if the magazine box can be moved up and down between the bottom metal and receiver.
  • If there is movement, (preferrably .020"-.040") torque action screws down to desired amount slowly, while continually checking for the desired clearance noted above.
  • If you can't move it, remove actions screws, bottom metal, and mag box.
  • Use a belt sander to carefully remove excess material on the magazine box that faces the bottom metal.  Remove only a little at a time and repeat the above procedures, until the amount of clearance desired is obtained.
  • You can also obtain the same results by using a fine cutting metal file, but to be sure you are removing the same amount of material from all sides of the magazine box, the belt sander method is preferred.

Bottom Metal Weights

One of the most common questions we here is; how heavy is your bottom metal as compared to my factory unit?  Well, while we feel that the added quality and durability of our bottom metal is a far better trade-off than the loss of a few ounces, we've compiled a list of our bottom metal and their respective weights.
As a point of reference; the Model 700 Short-Action BDL factory bottom metal weighs 1.9oz..  So in essence, on that model, you'll increase your overall weight of your rifle by 4oz. exactly.  What you'll be gaining, other than weight, is a 100% reliable part that can be reblued or finished to match your rifle exactly.  No paint scaling off of it, or unsightly gaps in the inletting.  And last, but certainly not least; a fine quality part that will last for generations to come and never fail when you need it the most.
