The installation of our 'Classic Gunsmith Adapter' into the stock of the Blaser R8 Pro rifles is relatively straight forward.
For a synthetic stock model Blaser R8 Pro which is mainly hollow on the inside of the stock with some structural bracing.
The key areas for a successful installation are to ensure that all measurements are taken precisely.
Ensure that the adapter is:
- Centrally positioned on the centre line of the fore-stock
- Does not obstruct other fittings in or on the rifle
- Has sufficient space for the adapter to fit in that part of the stock
- Has sufficient space to accept any bedding medium used (Hollow stock)
- Does not come into contact with the barrel
Time spent assessing the correct placement is well spent.
We would recommend a good quality 2 part epoxy resin with good tolerance to moisture & heat. We often use Devcon 10110' Plastic Steel Putty, but other good products are out there.
The putty rather than resin, as it is a little more forgiving in terms of unwanted runs & leakage, but will require a little more work to ensure good contact during the bedding process.
We understand that it is also a respected product within the United States, for use in bedding rifle actions. There are some similar requirements & considerations in fitting the 'Gunsmith Adapter'
The installation can be completed successfully by anyone who is confident in working on their rifle with access to some commonly found workshop tools.
Ensure that the rifle is safe & separate the rifle action from the stock.
Measure and mark the position for the adapter to be installed. Pick a position in the middle of stock, in the centre of one of the 'well' that occur between the strengthening cross-sections.
Within the stock of the R8 rifle, there is already a position moulded into the base of the stock that is intended for the fitment of a second sling stud/bipod mount.
- (Because the installation requires the well to be partially filled with epoxy resin, it make it difficult to get access the the "hex' headed screw that holds the 'Schnable' end on. Some Blaser owners may, therefore, prefer to use the empty well behind this one if this is an issue.
- (It is worth spending some time to mask up the rifle stock to prevent damage or marking, or contamination .)
Ensure that the stock is secured upside down in a suitable clamp such as a machine vice.
A small pilot hole should be drilled initially through the marked position. This should be followed by an 18mm hole drilled accurately following the pilot hole through the centre stock to accommodate the adapter.
We suggest using a suitably sized hole saw for use on synthetic stocks or 'Forstner' bit for solid stocks.
- Our recommendation is that you should use a pillar type drill, with a secure method of clamping the stock, to ensure accurate vertical drilling & prevent the stock from moving inadvertently.
When installing the 'Classic Gunsmith Adapter' into a synthetic stock, an 18mm hole saw will be the most suitable.
Initially, this will leave a hole that is too tight to fit the adapter.
Fractionally enlarging this hole with a compact rotary tool will open it slightly to create an interference fit with the 'Classic Gunsmith Adapter'.
Key the surfaces of the stock and adapter to be bonded and clean both with a suitable solvent cleaner to remove any dust or grease that might interfere with the bonding process.
The adapter can now be firmly pressed into place. This interference fit also assists to hold the adapter firmly in place once it has been correctly aligned with the stock. This reduces the risk of accidental misalignment during the bonding process.
We would recommend that you use some tape over the adapter to ensure the no unwanted movement of the adapter occurs whilst the resin is curing.
- (An 19mm saw can be used, but the fit is much looser, and more care is required to prevent resin migration or the adapter being unintentionally moved out of alignment.)
Ensure that the adapter is correctly aligned to allow the bipod to sit facing forward or rearwards.
It is these 'cutouts' that limit the left & right traverse of the bipod or create a fixed bipod when it is installed into the adapter in the reverse position.
- (At this point you can choose to have the can't tightening screw either facing the user or muzzle. The bipod can be used in both of these attached positions, but on way is fixed & the other permits traverse. The choice is down to the user's preference.)
Ensure that areas that you don’t want the epoxy to stick to that can’t be masked are coated with a thin layer of wax. (Neutral coloured wax shoe polish works well for this.)
Mix the epoxy according to the manufacturer's instructions, and then fill the area around the adapter, ensuring that it if fully surrounds the adapter from the base to the stock to the top of the adapter. Ensure that the resin won't reach the rifle barrel.
As the epoxy cures, some finishing & shaping can be completed.
Wait for the epoxy to cure, remove the masking material, clean & reassemble the action to the rifle, fit the bipod & check zero.
