[xibunkrlilkidsx]

for my final grade in my Solid Works class were have to draw something well.. i choose my ar15. but i need the dimensions of the upper and lower reciever. i can measure mine out but it would be much mroe accurate to use established dimensions.

just need to do the t-markings and some small fillets

where did you find the upper receiver at? i found the lower receiver easily. but my google fu could not bring up the upper.

thank you that is exactly what i needed.
