  3. Excellent Balance and Accuracy
    Former PD, and Firearms Instructor. The MK18 has excellent balance, even with a suppressor attached. Depending on where you place your Holographic Sight, you are able to balance the rifle on the side of your hand, right at the magazine port. Agreed, minus points for the plastic dust cover. I would have expected metal for the price. Charging handle needs to be ported to relieve gasses during suppression, and larger to accommodate easier and faster charging of the firearm. Overall a 5. Compact platform, light, and applicable for all defensive needs, urban or rural. Accuracy is great.

  4. Amazing
    went to sheepdog firearms Saturday October 26 2019 and shot this rifle and was blown away with the performance. This rifle did not jam nor have any failure to feed, it locked back on the last round and the only part that was i guess you could say problematic was the gases. Besides that one thing this rifle is amazing my dad enjoyed shooting it as well just can't wait until I'm 18 hopefully its still around

  5. ICON
    1 of 3 DD rifles I own. For such a short barrel it’s a tack driver. I run a ta31 on mine and it feels right at home on it. Always get people wanting to shoot it. Such a iconic rifle.

  6. Got this upper through Brownells
    Bought this upper with my tax return, absolutely love it and also my first DD product ever. This upper sold me for life, next gun or build I do will be Daniel Defense and I'm gonna do the M4A1 next. Most accurate barrel you could ask for, you truly get what you pay for...
