When I lived in the states I had several weapons but sold them about 3 years ago. Colt AR, Russian AK folder, HK 91, Benelli M1, couple other odds and ends. AK brake has a reverse thread and is locked in place with a spring loaded pin. Looking that young Sarjant in the eye whilst I removed the brake in seconds told him all he needed to know.

You can take what you have and improve it. We were doing that with Tamiya TUs 12 years ago and some of the results were astounding. My TU's, and ETO itself, is not a retirement plan. I am a tanker first and foremost and I provide fast service and top quality detail and running gear parts to our hobby. My accountant in US has repeatedly told me to close it, especially in the last couple years with the economic and political turmoil in US, EU and here but I won't do it. He sees only profit and loss, I see it as something we tankers need.
