Hey guys, I am posting here to get your input. I have an FN Collectors model m4 14.5 pin and weld from factory. Knights armament rail, covers and broomstick. Matech rear sight. Daniel defense grip. Magpul stock. Ambi charging handle. Ambi safety. I have a guy that is wanting to trade his ACR for my FN. I have never handled an ACR or shot one. Is it a good deal or should I be weary? I have plenty of AR’s and would consider an ACR but thought I’d ask you guys with first hand experience with them. Thanks |

The difference is 1.5lbs to be specific, but I'm of the opinion that a lot of people's ARs are unusually light rifles. 7.5-8.5 lbs is pretty normal for an infantry rifle; the M16A4 I was issued was around 8.5lbs, and my M27 was right around 8 unloaded. Most people's issue with the ACR's weight isn't actually the weight, it is the weight distribution. The newer rifles (made after 2016 or so) with thinner barrel profiles are much better in that regard than the original M4 cut barrels with the 1:9 twist. You can also get a 7075 aluminum non-QD trunnion from Templar Precision that shaves off 5 ounces, and also deletes the barrel washer and wrench for a few more oz of weight savings. I'd tell you what mine weighs but I don't have a working scale right now  I don't think a lot of people realize it, but there is a bit of a cottage industry built around supporting ACR development because the design is such that there are so many ways to modify them. If you don't want to get rid of the QD mechanism, .300 blackout and .450 Bushmaster kits are still readily available from Midwest Gun Works, and there should still be some 6.8 kits floating around. The ACR uses AR barrels with the only 2 differences being a smaller gas port diameter (piston guns use gas more efficiently and don't require as much) and a small turned down area where the op-rod support attaches; so pretty much any conversion you can do to an AR can also be done to an ACR. |

He has some sort of optimized setup for wrenching them off. His aluminum lowers are awesome too; he is working on one that takes the 6.8 Pmags for the 6.8SPC kits, and I'm not sure whether he finished the AK lower too. I have one of the QD sling mounts that replaces the loop on the stock and the extended BHO/release tab. All quality stuff |
