I will soon be releasing a Longshot spring kit.
It will consist of a 15.5kg (approximately) spring, a full size recoil buffer, a slightly larger O ring and some satchels of lube.
Testing has worked well so far, but I'm sure a brass breach will yield the best results. Obviously.
I'd give a timeframe and price, but I made the mistake of doing it too early last time and got both wrong.
I can tell you that I have ordered the springs, and will order the buffers on Monday.
I was considering doing a deluxe kit with the boltsled braces and some PVC "chocks" to lock the stock in place, not sure yet.
So I'm just putting the word out that it's coming, and am open to any suggestions/requests.
Cheers,
