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.
The following are links to the equipment we used in this video. We purchased these accessories ourselves, and we only recommend products that we trust and have been tested extensively by us.
