CQBR Block II 72 dpi
This rifle is chambered in 5.56 NATO.
This platform is built on a fluted 416R stainless steel barrel with a matte finish. All 5.56 NATO barrels are threaded with a 1/2X28 pitch.
All of our Bolt Carriers go through a R.E.M Polish process prior to nitride coating. The R.E.M Polish process reduces friction, improves part durability, improves oil retention, and improves contact & bending fatigue. Our Bolts are MPI (Magnetic Particle Inspected) and coated in a durable nitride finish.

Description

Here at TYPE-A, we are big fans of GWOT age firearms. One of these modern classics is the CQBR Block II which has become a modern classic. We have developed our own variant to call back on the glorious quad rails and short CQB style firearms of the day. Being a RESTOMOD variant, we have upgraded various aspects of this firearm to make it truly a modernized classic with old school flavor but all of the performance expected out of firearms today.

Our CQBR Block II  is equipped with a 10.5″ 416R Stainless steel match grade barrel with an ASR suppressor ready muzzle. The TYPE-A CQBR Block II is driven by our TYPE-A QPQ bolt carrier group w/R.E.M Polish. Equipped with a DGI (direct gas impingement) system and our new TYPE-A PMC Straight 2-stage trigger to give it consistent reliability time after time.

NOTE:  All of our rifles are Hardcoat Anodized and then Cerakoted to give you a longer lasting more durable finish.  We wanted your rifle to wear to the anodized surface vs. the raw aluminum surface like some of our competitors.  Just another added benefit making our rifles…TYPE-A.

Adjusting Your Gas

"If you’re running a rifle with an adjustable gas block, consider the following process for finding your sweet spot. First, close the gas port almost all the way. This means bottoming out the gas port screw and then backing off ¼ turn. Then insert a 1-round mag and fire. If the round doesn’t eject, open the gas port screw another ¼ turn and repeat. Continue this procedure until the casing ejects and the bolt locks back on the empty mag. Once you get good ejection and bolt lock open, open the gas port screw one more ¼ turn. This is your minimum setting for reliable function. Beyond this, you’ll want to group tune the rifle. Your barrel will group differently based on gas setting. If you’re selected ammo is performing good at your minimum setting, then great. If not, then try firing 3 round groups in ¼ turn increments up to 1 whole turn. You should find some improvement in this range."
