...i was wondering if lwrc's new ACB could replace the bolt in my ACR with no hitches...the bolt has a few modifications that supposedly make it sturdy as hell, and maybe a little more reliable in the extractor sping area...its dual spring...and nickle plated...they have 5.56 and 6.8...well here is the site:

tell me what ya'll think...i may try it out in a few months just for kicks...

I dont think so. The bolt on the ACR has done away with gas ring area. Also, I believe the cam pin hole is rotated 90 degrees and would not line up correctly. I havent hit the ACR bolt with a mic yet to see if the measurements are the same.

With all that said, I would say no it won't

...thank you cjt50...wow, to tell you the truth i haven't looked at the bolt outside of its carrier yet...so i wasn't aware of the differences...i figured lwrc being a piston system and acr being similar...*sigh* my dreams shattered...hahaa
thanks again buddy
