Anyway after a long wait look what arrived in the post today .
Orange Mod Works Alpha Trooper Massacre Kit - The Rifleman
Includes: Plunger assembly, 6kg spring, metal catch & trigger (because i pre-ordered), stickers, catch springs (2!), and destructions.
I'll now go through each piece in detail and then talk about my testing.
The Catch, trigger, and reinforcement plate are of extremely high quality. They are extremely durable with no flexing under any stress i can provide normally. The trigger has OMW logos on both sides and adds some nice weight to the blaster. The catch has none of the hollows of the standard catch and so i doubt it will be breaking. The springs that come with it are also longer and stronger than the original springs. The reinforcement plate is optional but i'm using it as i have the 6Kg spring currently installed.
The bolt has a better grip on the dart than the stock model, with the ID comparable to 17/32 brass (or at least the brass i have). It has a slightly wider section near the front for easier loading, and yes it vacuum loads darts if you try. The front is made of fairly thin polycarb though so if you wanted to this is where you could crack it.
The rear of the plunger tube is thicker than stock, presumably to protect against the breakage that happened to my original kit.
The rear of the bolt has a smaller ID than stock to reduce deadspace and to stop the dart travelling all the way back into the plunger tube. There also is no AR (obviously) and the 17/32ish ID region is just longer than a streamling dart length.
All the bolt assembly is covered in OMW logos for those of you that like aesthetics.
If you are using the 6Kg spring, unfortunately some extra reinforcement is needed where the priming bar attaches to the bolt sled. I just slathered mine in gorilla glue and clamped it down for 2 hours so it had properly set, and I have had no problems so far.
In some blasters (mine included) you may need to add a 1/4 inch spacer at the back of the Plunger Tube as it wont travel far enough to catch as the priming rod will bend because of the 6Kg spring. I just used foam for this like normal PT padding.
EDIT: Ranges with stock streamlines seem to hover around the 65-70ft mark with some streamlines hitting 80. My hot glue streamlines with added weights hit consistent 80s.
