I prefer a dmr over the srs for milsims as I find people are less likely to call a single hit (multicam is especially bullet proof) and you typically come up against several people in groups. The new Halkey Roberts Alpha inflator features and all new 'dog clip' so called because it's easily identifiable. The clip has four legs, a head and body! Cylinders should not be used if they are showing signs of deterioration. Such signs could be rust or scarring of the end cap. The kit includes one replacement automatic head, one 33g CO2 cylinder and one green clip 13mm wide.I was lost for words at how light this thing was despite it being 90% full metal. I could give this to a young teenager and they would be able to sport this all day without a problem. Definitely lighter than my G&G Scar-L. This is a specially imported genuine manufacturers part and is very easy to fit in seconds. It has no shelf life. The kit includes one replacement bobbin, known as the 'superbobbin' which will fit all Halkey Roberts mechanisms. Its yellow in colour, your old part may have been red. Also included is a 38g CO2 cylinder and the relevant clip. I have never handled an airsoft weapon of this quality. When they call it a "training weapon" they werent kidding.

The Hammar MA1 inflator can be recognised by the pull cord which is yellow and different to the standard hammar kit which has a red pull cord. (Sometimes mis-spelt as Hammer.) I'm using a Balystik reg with mine. Faultless so far (have one for sale on this forum at the mo' as I had two) I have had my mtw for a week or so now and love it can't wait to get out on the field with it only question I have does 125psi seem a bit high ? It's running 273 FPS on .32The Hammar MA1 inflator can be recognised by the pull cord which is yellow and different to the standard hammar kit which has a red pull cord.

The gun itself feels really solid but is so light! The finish on it though looked rough and dusty so just needed cleaning down after delivery. Consistency wise i run it at 65psi average to keep under the limit and theres about a 5fps variation. Not as good as some have got it, but ok for me.
