Has Any Installed a Barrel Using a Magpul BEV Block?

Recommended Posts

Has anyone installed a barrel into an upper using a Magpul BEV Block?

 

The reason that I'm asking is that I'm mating a BCM upper with a BCM 16" barrel and the fit between the two is extremely tight. My plan, when the time comes to install the barrel, is to follow the advice on the BCM website and put the barrel in the freezer overnight and to heat the upper with a hair dryer, as well as coat both pieces with a thin film of moly grease. 

 

Here's the real question...

 

What's the best way to use the BEV block in order to get the barrel properly seated into the upper once I've got the barrel extension mated with the BEV block? Is there anything wrong with using a block of wood and dead blow hammer on the back of the upper to mate the two pieces or should I just try to "man juice" the thing on, hoping that the heat and grease will allow the barrel to seat itself properly?

The BEV block isn't for seating the barrel it's to take torque off of the extension pin and transfer it to the lugs.

Mate the barrel and receiver then mount on BEV block and tighten barrel nut.

Stand the receiver up on end ( use a folded towel under it )and tap the barrel down till its seated

I don't feel you will have that much of a problem fitting the barrel to the upper receiver.  Heating the upper is the way to go.  I have seated many a barrel to the upper and only a few times did I have to heat the upper for a little more room, never have I chilled a barrel.  A little moly and some heat and it will slide right in.  Do not go pounding things, bad things can happen.  If you have to, you can use a Scotch Brite pad on the receiver and barrel extension to slick things up and remove any burr, etc.  Remember to tighten and loosen the barrel nut about three times to have the barrel nut and threads pre-stretch, to stop and possibility of the barrel nut loosening up after you start shooting it (35-80 foot lbs). Make sure your upper receiver barrel face where the barrel extension seats down to is square before mounting the barrel.  Good Luck.

I installed my barrel yesterday using the BEV block. It was a super tight fit between the BCM upper and barrel, even after heating the upper with a heat gun for one minute (as per the BCM website) and putting some grease on both the barrel extension and the upper. 

 

I got the barrel installed about 90% of the way by hand without using the the BEV block. For the last 10% of the way I locked the barrel extension into the block and then pushed the upper onto the extension (being extremely careful not to bend anything).

 

This was the first time that I've installed an AR barrel so I've never used any other block; however, I'd give the BEV block a solid "C" in terms of making the job easy.

    • I very seriously doubt this has anything to do with terrorism.    1) Harbor pilots are VERY seriously vetted, and highly trained. Not to mention extremely well paid. My experience knowing a few of them, and knowing how they are recruited and screened tells me that there is a slim to highly unlikely chance that a harbor pilot would have participated in anything like that.    2) Maintenance of foreign flag ships is well known to be dubious. Especially these days. These were NOT US flag, Jones act sailors. It was (to my understanding) a largely Indian crew on that ship, with a Ukrainian Captain. Indian crews are not exactly known for being stellar.    3) The bunkers (fuel) these ships use is ‘Bunker C’, which is a heavy, dirty fuel oil that can, and usually is, pretty contaminated. This stuff ain’t your car grade gasoline or diesel fuel. It’s nasty.   It requires nearly constant filter changes and maintenance to the engine/generators. The ship took on fuel prior to departing port, which would stir up all kinds of shit in the fuel tanks, which would contribute to particulates in the fuel lines/filters.    4) I’d say the posting of the chief engineer for Maserek above was pretty spot on as far as chain of events.    This was a shitty accident, with horrible timing and outcome. Not a terror attack. 
    • I saw Lara's interview on Bannon's War Room, and that gave me pause for thought. Her conjecture depends primarily on the veracity of her sources. Regardless, if it's not applicable in any way to this ship disaster, the methods described seem valid to me. And worthy of consideration for the future. As I said before, IMO something is coming.
