If you have a look at my website you'll see I've polished a number of T**ds and a LOT can be done BUT if the original engineering is poor then it's poor.
Your actually better off with something well made out of good quality steel than something that has been "improved".
I got the BAM out of curiosity as a project and making it into an acceptable rifle is an uphill charge.
There are machining marks/gouges were there should be none, the original stock split in 2 paces and the screws are made of cheese!!
Oh and that is not counting a valve that did not self regulate in any way, a transfer port filled with solder and re-drilled to reduce the FPE in a poor attempt to keep it under 12FPE.
Don't be deluded, what you get is in some sort of proportion of what you pay, pay absolute bottom $ get bottom quality.
If you can buy AA, BSA, Falcon.
