| Can you use a Panther Claw type receiver block to rebarrel a rifle? Are do you have to have a action block |
|
If your upper is a FT, I believe you can turn it to one side (base of block on one end of vice jaw and FT end of receiver on other). Use a piece of plywood or thick cardboard between the rail side and vice jaw to protect the FT rails when you tighten the vice. I believe that the internal part of the block that you have prevents the receiver from flexing during debarreling and rebarelling. I have seen this method done somewhere on the board. I believe it was ADCO with pics of their block, which is very similar to the one you've described. Ron |

This is what I use. The Peace River block. Is this what you have???  It has a piece to fit inside the reciever as shown and the other piece folds around the reciever then it fits in the vice. edited to say: It will work on either flat top recievers or A2s'. Have used it on both. |
Looking at pics of the Panther Claw I would say no. There would be way to much stress on the pivot and take-down pin lugs when you torque the barrel. You need the type that completely encloses the receiver, these provide the receiver with necessary support. The Panther Claw looks like a block used when you want to support the upper in a vice to install optics or do actual work to the receiver, not to install barrels. Panther Claw This is the type of block you need.

The pic on Delton's site seems different from the one on dpmsinc.com (search for "claw"), though supposedly both are called "Panther Receiver Claw". dpmsinc.com shows a better pic of it showing the extension that fit into the upper receiever. This should take some of the torque so not all of it is applied to just the pin holes. I believe some members have used it for rebarreling just fine. |
Well that does clear up how it functions, but personally it still looks flimsy. I guess I'd have to see it work in person. |

I have a similar action block set I recently purchased from BC. Its marked M1S and is solid with the full insert. jcncc, what type of upper are you working on? FT or A2? Obviously, it's arguable that the "Claw" will work fine for barreling/debareling, but it looks like there would be alot of stress on where the mounting pins are inserted. ETA: I am referring to the pic of the action block on alpo's post. I pressed the "reply" button instead of "quote"  .

I have a peace river action block but do not have the insert that goes in the upper. Is the insert really needed or can it be used without it? If I truly need it where can I just get the insert? BLM |
That is a internal support. Gives the reciever more support. It should have came with your block when you bought it. I can't answer if its absoultely necessary or not. You might give them a call and may be able to get one. (it should have came with the block). Here is the address and phone that is on the direction sheet. Peace River Arms & Accessories, Inc. 3315 Reynolds Rd. Lakeland, Fl 33803-8332 Phone 863-665-1930 |
Just FYI, its the exact same block M&A, Model One Sales, Bravo Company, and a bunch of others sell. I dont think its made by Peace River Arms. Edit: Link to Bravo Companys for sale add on the EE www.ar15.com/forums/topic.html?b=7&f=25&t=251786 |

I just talked to a smith at LaRue Tactical and they use the DPMS Claw and told me that it's what they recommend to use for barreling and installing their rails. The other method they use is sandwiching the receiver in two pieces of plywood and putting it in a vice sideways. |
