Great scope mount for my Lee-Enfield. Very easy to install; fit perfect. Very pleased.

No 5 Enfield with Bad Ace mount. Weaver K2.5 60B vintage scope. Think this is as about as close as you can get without an actual No.32 mount and sniper scope.

Perfect fit on a 1941 Lee Enfield. Very pricy but you get what you pay for!

Great service and the item arrived quickly.

Easy to install and works with my scope. Nice design.

Perfect fit on Gibbs Rifle Company 45-70!

Works as stated, well made.

Awesome product to bring some more accuracy to a vintage rifle, good piece of kit

Good railroad for my 303.

Thanks so much, I planned on putting the old Enfield into service again. Eyes have gotten a bit weaker, so this is an awesome way to put a scope on it without decreasing its value. Thanks for a great product for a very reasonable price. Sincerely, Bob

Great. Very easy to install

I have three rifles with this scope base and they are incredibly accurate ! This scope base is all you need if you want top accurate results with Lee Enfield No 4 mk 1 Military or Sporter version.

Niiice

Made this old rifle like new again it was super easy to install and definitely worth the price for how it made my 45 able to take a scope

Wish things were better with our neighbors to the north, had to pay a little extra for an excellent product. Thanks again!

Great all around !

Made my 45 look absolutely amazing and ready for hunting

Mounted perfectly!

perfect fit on a near 100 year old gun

Expensive but it fit like a glove and worked great

Very pleased with the results

The installation steps worked as advertised on my 1945 Lee-Enfield No4. The shorter ejection bolt did not work for my rig, but the extra ejection bolt that was also included did the trick after some grinding/filing. Thanks for including the longer bolt! I’m ready to try it out at the range and hope to get many years of use from this well designed, thought out and solidly built mount.

Incredible design and super easy to install. The included instructions and online video make install a breeze. Mount is very solid and has no concerns with shifting at all. Shipping time was great considering it came from east coast to west coast. Would highly recommend to anyone looking to install a scope on their rifle.


Temporarily out of stock. Expected to be restocked in mid-August.

NOTE: Fits both Lee-Enfield No.4 and No.5 and does NOT fit any other Lee-Enfield models such as SMLE and No.1

The No.4 and No.5 (Jungle Carbine) have aperture sights that located at the back of the receiver. The rear sight base looks like two "ears" after the rear sight leaf is removed and the bridge charge guide is in front of the rear sight. If your rifle does not look like this or was "sporterized" (e.g. rear sight base cut or charge guide removed), this scope mount will NOT work. Please contact us if you are not sure. 

  • The Gen 3 version works with all safety bolt types, including the "Kicked Leg" type:
  • Features the unique all-steel NDT side mount base and rock-solid 3-bolt mounting system:
  • The Gen 3 version kit now comes with a flat rear sight leaf that allows easy bolt removal without removing the optic. 

  • The ultra-low profile picatinny rail allows you to mount the scope as low as possible to the barrel and provides the option to keep the original iron sight as the backup : 
    • Rock solid, no gunsmith required, easy installation in 20 minutes
    • Fits both Lee-Enfield No.4 and No.5 (Jungle Carbine) 
      NOTE: does NOT fit any other Lee-Enfield models such as SMLE and No.1

    Installation Video: 

    This accuracy comparison video compares 3-round, 5-round and 10-round groups of Lee-Enfield No.4 and No5 jungle carbine back-to-back at 100 yards. These are both regular, unmodified standard rifles in full military configuration, except the No-Drill-Tap scope mounts, of course.

    On American Rifleman, August 12, 2020 - “…, but the “Jungle Carbine” was plagued by a “wandering zero” problem that proved to be the handy little rifle’s undoing. After much investigation, the accuracy problem was found to be “inherent in the design,” and the No. 5 was declared obsolete in July 1947 …” 

    Shooting at a frequency of 15 seconds per round, the No5 gave us a respectable group when the barrel was not too hot. However, when the barrel heats up, we got more “fliers” than the No.4. In the end, it still did a solid 4.5 MOA 10 rounds group, which isn’t too bad for a light, short-barreled military rifle.
