when i first embarked on my quest to make what is now known as the m14s-cqb .... first i tried a S&J hardware grip adapter just like charles is doing. As you all know I passed on the idea pretty fast for the same reasons being mentioned above.
then i looked at all the shotgun adaptors and again..... not what i was after.
I did not want a finished product that was simply a cut off stock relying on a main bolt and a bunch of epoxy...
now I have to ask myself...... do I reveal the secret of the M14S-CQB?? after all i charge good money for those hehehehe
so here's how it's done
you need a genuine AR 15 receiver half.... the rear portion, cut off at the trigger.
then cut horizontally in the mill to remove the grip bae from the buffer tube thread and body, the we mill 1/2 inch out and reattach the grip base to the body with buffer tube thread. this is jigged then tig welded back together to make a one piece solid adaptor.
then i cut the usgi stock much further back then shown above and hollow it out. the top and sides of the gi stock remain, the bottom is open.
the adaptor is then imbedded into the stock, not screwed and glued.
I'm stopping right there as the rest will remain secret LOL.
my new manufacture stocks feature a once piece proprietory, machined mount that is part of the stock from the first stage of the process instead of being added in after via imbedding. For those of you who think my usgi stock mod "fee" is too high at 495.00 , remember this, 50.00 for the epoxies i use, per stock, the cost of the usgi stock at 129.00, the 12 inch rail at retail 28.50, and about 20 hours on average per stock to have a blemish free finished product... does not include paint, clear coat, sand paper, machine screws..... and oh i forgot 65.00 my cost for the adaptor and no..... these are not sold seperatley. 495.00 for a usgi stock mod from me is not such a bad deal hehehe
Once my new adaptors are done and i have the new stock production running smoothly, I may offer usgi stock mods for customers supplying thier own stocks again soon but for right now my plate is full.
have fun with the projects guys, after all, it's all about havin fun
