I won't lay out how we did certain things or how we overcame certain obsticles so that someone else can duplicate our R&D work (3 years worth), but I will tell you that no one to my knowledge has made a bullpup design this short before so no no one else has proven the design that I am aware of. We designed the complete trigger assembly, linkage, and remote trigger from scratch. The tube simply bolts to the stock with 2 bolts. As far as keeping the scope and barrel pointed in the same direction, based on the accuracy and repeatability we are seeing so far I have no concerns there. Point of fact the design has side stepped some accuracy issues associated with conventional designs. I nshort it incorperates all of the features and design ideas I have always wanted in a long range rifle, performance points - 3100 fps, 1/4 MOA, single digit ES, not temperature sensitive, totaly repeatable and still retains the ability to fired accuratly from positions other than prone. To this end I could not be happier with the finished product. Hope this answers your questions while keeping in sight that certain things I just am not taking pictures of or telling about, sorry.
