    Light weight

    I was looking for a lighter BCG for a build and after comparing several this was my choice, I’m very happy with it, it is well made and works great.

    Ar-10 bcg

    Posted by Unknown on 5th Jun 2020

    Very good bcg. It's very lightweight and there is a significant difference in weight compared to a standard bcg. No problems at all at the range. It's pricey but if you're looking to reduce the weight of your rifle the barrel and bcg are typically were you want to start. Overall, I' am very satisfied with the bcg.

    Not exactly .66oz and no email response from JLbillet

    Posted by Blaine Leach on 8th Apr 2020

    I purchased this within the last year and while I am pleased with the performance of the product, I am not pleased with JLbillet. I believe all these titanium bcgs are made by toolcraft. The weight advertised on this website suggests it is 10.56oz when it is in fact closer to 12oz like the toolcraft ones. When I reached out to JLbillet I got no response. At the time, Brownells had it on sale for 320$ and so upon learning that toolcraft makes most of the titanium bcgs you’re getting the same bcg at the same weight anywhere you get it. I bought from JLbillet thinking it was going to be their “advertised” weight. I recommend waiting and finding it cheaper from any other site.

    this product is amazing it really cuts weight however had a big problem with it punching holes through primers! it was only a minor fix the firing pin was about 4/1000 to narrow at the point got a slightly fatter firing pin and it fixed the problem!

    If you are looking to build a light weight AR10 this should be in your sights

    Posted by Pmac on 26th Jul 2017

    Next to a light weight barrel there is not one single component with the ability to cut weight like this. If a light weight AR10 is your goal this is one of the keys to getting there. A savings of ~8oz over a standard BCG is fantastic but the 1/2 lb drop in reciprocating mass can't be ignored. A side weight benefit is reducing the buffer weight to match. It’s a win/win. As far as the quality is concerned I stripped the bolt and carrier completely while checking headspace and found the product machine work to be fantastic.

    Follow up on (Awesome BCG!!!)

    Posted by Corey Ellis on 16th Aug 2016

    I took my completed .308 rifle out to the 300 yard range recently. I was very pleased with the results. This BCG operated perfectly. I used hornady and federal ammo and both brands ejected fine without any issue. All my primers on all my rounds had a very clean and uniform dent right in the center. All in all I am still happy with this purchase and would definitely buy a second one.

    Very nice

    Posted by Unknown on 17th May 2016

    Nice quality and machining. The 308 Titanium BCG is only a little heavier than a standard 556 BCG. My build is still in process. I will update when I get the chance to cycle.

    great upgrade

    It was unfortunate that the carrier had a nick on one of the bearing surfaces,not happy at all about that.

    Best thing you can get for your AR308

    Posted by breastroker on 27th Dec 2015

    I got my BCG direct from the distributor a couple week before they became available. I used it to create the lightest AR308 with 18 inch barrel anywhere! Got it down to 4.99 pounds without scope. With a good adjustable gas block and good muzzle brake, my 5 pound AR308 shoots very soft, just a little bit more than my 6.8's. But with action weights cut in half, the hammering is down from sledge hammer to ball peen. I am getting half inch groups or better, and the titanium BCG is a big part of it. I have hundreds of rounds shot with this BCG and it still looks like new. Zero issues with the brass, no deformation or swiping.
