mega 308 - bolt catch issue

[Aye-Are-10]

Hey guys, it seems like ive seen someone talking about this before, but I cant find it.

Just "finished" a mega maten 308 build and the bolt catch wont hold the bolt back reliably. It holds it back at first and then if I even look at it, it releases. It is the bolt catch that came pre installed on the reciever set so I figured I wouldnt have to change anything. Also, im using a factory DPMS bcg. Have not shot it yet.

Any links to other threads or advise would be great. Thanks in advance.

I have a Mega and haven't had any issues yet. That being said, I bought a Phase 5 bolt catch because guys who have had issue like you moved to it and have been doing fine. Here is a thread all about the Maten receivers and anything else mega The BIG Mega MaTen Answer thread (FAQ covering LPK, Barrels, Bolts, Stocks, EXT) Check here first! -

LV Med, thanks for the link.

Wish I would have found this before I started my build..

What type spring and buffer are you using? Are you sure its catching the bolt itself and not the bolt carrier just behind the bolt lugs? You should not have to purchase an aftermarket bolt catch. Something else is going on.

Jp 308 spring and dpms rifle buffer (a2 buffer tube w/ prs). Have to check when I get home on the second question.

Thanks for the reply

If it does turn out to be the spring and buffer you could always take a look at slash's buffers. They specialize in extra heavy buffers and springs specific to the buffers. Hope you get it sorted out. The 10's can be a bitch to get running right sometimes.

Is your DPMS rifle buffer a .308 buffer or standard rifle buffer?

Its a .308 it said. What is the difference? Just heavier?

 

[Aye-Are-10]

It is doing this when I do a function check, I have not shot it. Could someone please explain why the buffer would cause this? Thanks

 

[wareagle700]

The lengths are different. Because the .308 carrier is longer, the buffers have to be shorter than standard buffers.

I don't know if this will help, but I installed a UBR stock on mine and when I pulled the BCG back it would lock back on an empty mag, but not on the bcg catch. I finally figured out this was caused by the original buffer and spring that were slightly too long to work with the UBR, and so the bolt was not retracting far enough back to lock on the edge of the catch. I picked up a JP silent captured buffer spring set and all is well again.

 

[Aye-Are-10]

Ok, got it. This is what I bought.

DPMS Buffer LR-308 Rifle

I would think this would be the correct buffer? Then again, im no rocket scientist. Thanks

 

[wareagle700]

Yep, that's correct. See if MEGA will send you a replacement. You shouldn't have to fix this on your dime.

 

[Aye-Are-10]

Will do, ill ask if they suggest anything before that. Ill post the outcome, ive heard nothing but good things about their company. Actually, im looking forward to talking to them. Thanks again!
