Great customer service

The Toolcraft 7.62x39 bcg was the first item I ever ordered from Acme, item was lost in transit via UPS, however Acme was notified and a replacement was mailed out to me the same day and now I'm a customer for life, that will spread the good word on this Great American Co.

Posted by Amiel C. on Nov 13th 2018

After purchasing a PSA 7.62x39 upper for a new build project, I was in need of a spare BCG for a back up. During my search, I came across the Toolcraft BCG on Acme's site. It caught my eye because not only was it MPI, which many are, but it was also HPT, which I didn't see on others. Glad I took the chance. I'm actually useing this BCG (paired with an enhanced firing pin) as my primary and keeping the one that came with the upper as my back up. I've put 200 rounds down range without a single malfunction of any type. In my opinion this product is "the best bang for your buck", no pun intended :) I'll try to update this review in the future if possible.

Nice BCG Picked up this BCG as a spare. Price seemed good and I've always been happy with the products I've bought from Acme Machine. Received the bolt in just a few days and gave it a very thorough inspection. Nicely built, functions smoothly, properly staked, very happy with the item. I may purchase another one just so I'll have 2 spares. If you're looking for a 7.62x39 BCG don't hesitate to order this one.

Worth the money This bcg is absolutely worth

Posted by Jojo on Apr 16th 2018

Worth the money This bcg is absolutely worth the money and then some. Super glad i bought this one too since its capable of auto firing. Also, there arent many venders that keep these complete bcgs in stock, but this company does and i love that. Now dont get me wrong, the cheap tul ammo that im using tends to have have a hard primer thus 2 out of 40 bullets ended up with dented primer strikes so i had to shave off just a thousanths off of the firing pin but honestly in my opinion, i should have to do that if i decide to use cheap ammo. I would be worried if i didnt have to do this since this bcg is mil spec. I also had 1 out of 40 bullets that did not feed but i can assure you that was because of the cheap promag i bought for the rifle. I have fired 30 more after the first 40 that were fired from my rifle and had absolutely no malfunctions at all. I will be putting this bcg through its paces with a tortue test tomorrow in order to truly deem it reliable. But as far as the bcg as itself, pretty amazed with it. Thank you, Acme Machine! By the way, to anybody thinking this is review was made by someone who works at acme and/or is sponsored by acme, well i just want to tell you that i wish i was sponsored or even worked for acme hahaha.
