My .308/7.62mm fullauto conversion- Plug & Play Success!!

[TactAdv]

Okay, posting some quick crappy pictures here...Peter asked to see the breech end of the S.A. BBL....

Things to note- the magic of these S.A./Lyttleton BBLs is that the SHANK is about .090" shorter than a std .303 BBL shank, which then allows the std unmodified .303 bolt face still with feed horns protruding forward to fit against, i.e, lock against the std .303 locking shoulder, i.e., since the shank is shorter by the same distance as the length of the fee horns, it doesn't interfere. Note that these pictures clearly show the ONLY cut/relief on the breech face is for the EXTRACTOR claw......no cut for the bolt feed horns to drop into!

It's a brilliantly simple solution, though it would seem that in so doing you'd have a lot of unsupported cartridge case extending, it doesn't seem to matter one wit, in actual firing. None of the .308 fired cases exhibit any bulging at the case head area......so all's good. A brilliantly stupid solution that works....

I'm probably going to go shoot it more tomorrow again, so I will get some video of it shooting in .308 with all these conversion parts installed.

Again, the total conversion consists of:
-S.A. 7,62x51MM NATO caliber barrel (Lyttleton proprietary design)
-S.A. 7,62mm extractor (suspect identical to all other 7,92mm/7,62mm extractors)
-using unmodified Bulgarian Zb-39 25rd magazines.
