- FAQ -
Our second and final prototype has been fired!
Minor adjustments to be made ASAP.
Once the necessary engineering notes are completed we will be producing the Gardner Gun as a full-time production item.

The FAQ and manuals for the new 1885 Gardner Gun are being written, please check back for updates.
We discontinued the "K" so that we may have more time for the Gardner Gun.
Enfield .45 conversion's.
Most details of the .45 conversions are essentially the same as the "K".
We will be writing a new build manual for it.
Enfield "K" 7.62x39 is now discontinued!
Leaving these instructions up for a while to help with any unfinished builds. Most of it also applyies to .45 conversions.
Assembly of the "K" is very straightforward, but will require a couple of steps that may be somewhat difficult for individuals who are not trained gunsmith's.
1. Due to inevitable minor variances in Enfield actions we cannot fully head space the barrel and bolt before delivery to the customer.
Final head space has to be done after the barrel is trial fitted on the buyers original receiver.
For the new style lock-nut barrels the chamber is fully reamed to size.
2. The extractor notch will have to be cut in the chamber end of the barrel. This can be done on a milling machine, or by hand using a Dremel® tool or sharp square file.
3. The magazine well in the fore-end wood may have to be relieved to make room for the front end of the magazine adapter. This is pretty easy with a Dremel® tool and burr or a small wood rasp.
4. An Enfield receiver vise and barrel wrench are STRONGLY recommended for use in building the "K". Poor quality improvised tooling can easily ruin the Enfield action!
S.I.A. cannot take responsibility for any conversions that we do not fully build, as we have no control over the quality of work performed by others.
* There is no need to send us your old barrel, we supply one of our Match Grade replacement barrels as a standard component.
How do I get my old barrel off? It's REALLY stuck!
Seven out of ten Enfield barrels are extremely hard to remove, we find that the easiest way to get them off the action is as follows. If you do not have a lathe, a local machine shop or gunsmith can handle this for you at a nominal cost.
A. Strip the action of the stock, rear sight, and all small parts which might come loose while the action is spinning in a lathe.
B. Strip the bolt assembly, you will need a firing pin removal tool.
C. Insert the bolt body into the barreled action.
D. Mount the barreled action in a lathe with a "swing" of 9" or larger.
E. At the receiver end place the firing pin hole in the bolt body on a live center mounted in the tail stock.
F. Chuck the barrel in a self centering three jaw chuck.
G. At very low speed turn-off the barrel shoulder (Chamber area just in front of the receiver) to 1" diameter using a thin blade parting tool. Wear safety glasses!
H. This will relieve pressure on the barrel shoulder and threads, the barrel should now unscrew easily.
Since the barrel shoulder has been machined back the barrel is now scrap, and will never be usable in .303 again.
· Why use the Enfield No. 4 as a donor?
· The Enfield is reasonably inexpensive as a donor gun, it has a strong and well proven action, and originally used the same bore diameter as our conversion. It also has a factory detachable magazine, so converting to our AK Mag. adapter is relatively simple.
· Where should I look for an Enfield No. 4 to use for conversion?
· The Enfield No. 4 has been imported in large numbers over the last few decades. Many of them can be found already "sporterized" at gun shows, pawn shops, or garage and estate sales.
Many gun shops will have a couple of Enfield No. 4's on hand, try to buy a gun you can examine in detail before purchase. Since you intend to replace the barrel you may get a gun cheap if it has a poor bore.
· Why not use another gun, like a Mosin-Nagant or Persian Mauser?
· Those guns are more difficult to do, and would end up being more expensive.
The Mosin-Nagant has a too narrow magazine well, the Mauser has a floor plate and internal magazine. Besides, I like Enfield's!
· Aren't you destroying valuable collector guns?
· No, the guns to convert have little or no collector value. They are usually previously modified, sourced from foreign military surplus, or they have been "FTR" and then sold to third world countries by the shipload.
· Why is the converted Enfield more accurate than an SKS or AK-47?
· Mostly due to the bolt action, heavier and strait barrel (you should see an AK barrel rotated between centers, they are curved!), and careful setting of head space. The better fitting stocks do not hurt either.
· What made you decide that there is a market for these guns?
· We had a retail gun store, several customers came in looking for a bolt action rifle in 7.62x39.
The only guns available were Ruger® and CZ® rifles, with high retail prices and fixed magazines.
· These prices defeated the purpose of many of the customers, they wanted a gun that was inexpensive to buy, accurate, cheap to shoot, in a center fire caliber suitable for deer hunting, which also used detachable magazines.
· Can I change my gun back to .303 British?
· Not easily. The receiver is not modified, but the barrel would have to be re chambered, the bolt head replaced, trigger guard alterations are permanent.
· How powerful is 7.62x39, how far can I shoot accurately with the converted gun?
· The 7.62x39 is very similar to 30-30 Winchester®, it is excellent on game up to deer size, it is very accurate to 150 yards, and reasonably accurate to 300 yards. It will reach much further, but hitting a target at long range will take more skill.
· Can I put a scope on my Enfield K?
· All standard Enfield accessories will work with the "K". We suggest a 2.5-8, 4X or 6X scope in 32-40mm objective lens.
· What magazines fit the Enfield K?
· We use the Romanian AK single stack "WASR" mags. 5 and 10 rounds mags fit, due to the varied dimensions and quality of the mags minor fitment is sometimes required. These mags are usually available for $15-$25 each.
· It has come to our attention that there are two Romanian magazine designs on the market, the correct "WASR" mag. for the "K" is noticeably narrower at the front than the main body.
· Why not use the 30 rd. double stack AK mags, or a 100 rd. drum, that would be cool!
· That is possible, we built one action with a 30 rd. magazine as an experiment.
. We were not pleased with the amount of metal that had to be milled away for the magazine to sit high enough for reliable feeding.
· Removing so much metal from the receiver potentially opens us to an unacceptable level of liability, some one could claim that we had weakened the receiver by that modification.
· Many states also limit hunters to a 5 rd. magazines, others have bans on magazines holding over ten rounds.
· Using 5 or 10 rd. mags saves us from having to keep track of which states allow the mags we want to supply with each gun.
· Are you planning to make the Enfield K in any other caliber's?
· Not really. Most other caliber's do not work well with the Enfield action, and there are plenty of guns available in those caliber's.
· What scope mount works best?
· Our own, of course! ;-) The lowest possible mount, featuring a "Picatinny" rail and a "U" notch so that original sights may be used witout removing the scope base. Available for No. 1, Ishapore 2A, and the No. 4 or No. 5 Enfields.
These mounts allow the rear vernier site of a No. 4 or No. 5 Enfield to remain on the gun during use!
· Is the completed conversion still a C&R gun?
· Under our understanding of the law it is not.
