This page is showing my progress with my next and most accurate pulse rifle to date. I know it isn't perfect but it's close enough for me.
CONSTRUCTION
This is the barrel shroud from a cheap Spas 12 bb shotgun modified with holes cut for the grenade loading and ejection of empty rounds as well as a new front end and rear extension to fit working trigger and the insides are the spas barrel and magazine tube with dummy bolt for the ejection port.
The carrying handle/shroud made of styrene sheet from plans drawn up years ago is actually the same one from my pulse rifle mk 2 as the whole gun is basically an upgraded version of it using the same thompson gun and shroud where everything else is new.
The core of the gun is the thompson m1928 which should be the m1a1 but works with some modification. The block at the front is to help fix the underbarrel grenade launcher which we'll come to shortly.
The adjustable stock for the rear of the gun.
The magazine surround with hole for electronic counter that it probably won't have...
And fitted to the grenade launcher along with the barrel vent.
Test fitting of parts. >
Work on the front of the magazine shroud.
Mag housing finished.
PAINTING
In order to easily weather the gun after painting it I heavily primed it in a mettalic silver colour followed by the main colour so that when rubbed with scotchbrite the silver will show through giving it a worn appearance.
Shroud done and <primed. Firing parts finished.>
Simple locking mechanism for the stock. Main painting finished so time for a test fit.>
<Minor adjustments to the shrouds before fitting. 
Nearly finished.....>
<And after some weathering and with new mag base... 
From the back>
<And the front
And for comparison here's PR number 1 built around a blank firing M16 and with working counter and M203 grenade launcher.
And PR number 2 built around the same thompson i'm using for the new PR and also using the same shroud but this one had a scratchbuilt Spas 12 cage at the front.
SCREEN USED PULSE RIFLE
A few years ago I made a trip into London and visited Alien War and had an experience i'll never forget. In the lobby there was a small museum of props from the film and on one of the walls was a pulse rifle which I was told was used as a background prop in the film and at the time I was thinking about building one myself so I asked if I could take some pictures and here they are.
The rifle was all metal apart from the hard rubber pump grip, wooden pistol grip and magazine base to replace the original which was lost and very heavy. It was manufactured from a deactivated Thompson M1a1 with a real Spas 12 cage for the grenade launcher which didn't work as I tried the pump and it just slid back and forth with no movement from interior parts.
